If you suddenly encounter Activation Error codes such as 0xC004E016, 0xC004F210, 0xC004F034, and 0xC004F00F on your Windows 10 computer, then they all point to the same issue – Invalid Product Key or Version mismatch. When you see any of the aforementioned error codes above, it indicates that you are either entering a wrong product key or you are using an incorrect ISO when installing it on your computer. In such cases, you may see either of the following error messages:

“You are running Windows 10 Pro, but you have a valid digital license for Windows 10 Home.” Or: “The specified product key is invalid or is unsupported by this version.”

If you got the error code 0xC004F00F then it means that you’ve entered a product key for the Enterprise edition of Windows to activate Windows 10 Pro or Windows 10 Home. It could be that you have a key from your work and you accidentally use it on your Home PC. If you got the error codes 0xC004E016, 0xC004F210, then it means that you have entered a product key that is meant for a different edition or version of Windows. On the other hand, if you got the error code 0xC004F034 instead, then it means that you have entered an invalid product key or a product key for a different Windows version. Whichever error codes you have, refer to the possible solutions given below to fix the Invalid Product Key or Version mismatch Activation Error in Windows 10.

Option 1 – Try running the Windows 10 Activation Troubleshooter

The first thing you can do to resolve this Activation error is to run the Windows 10 Activation Troubleshooter. To do so, follow these steps:

• Go to Settings and then select Activation.
• After that, click on the Windows Activation and then troubleshoot. This will help you address most of the commonly found activation issues in Windows devices.

Option 2 – Try purchasing a new license

There is an exception offered by Microsoft – if you are connected to a Microsoft account prior to the hardware change, then you can most certainly use the same license key to reactivate Windows 10 again. Microsoft calls this an “Exception path” which should be fixed easily by the Windows Activation Troubleshooter as pointed out earlier. However, if the Windows Activation Troubleshooter isn’t able to resolve the error you can try purchasing a new license. In such rate case, even if you do have a Microsoft account available on your Windows 10 computer, and if Windows was never activated, this solution will not work. And if you haven’t connected your Microsoft account with your Windows 10 computer prior to the major hardware change, then your only option left is to purchase a new license. For you to do that here are some steps you can follow.

• To purchase a new Windows license, the first thing you have to do is click on the Start button > Settings > Update & Security.
• From there, go to Activation and select the “Go to Microsoft Store” option.
• After receiving your new license, you need to go back to Update & Security then go to Activation and select the “Change product key” option.
• Now update your Windows 10 computer using the new key and it should automatically activate your computer.
• Next, you have to create a Microsoft account or connect to your existing local account to your online account.
• Once the system links the key and the account, you need not buy a new license in case something like this happens again.

Note: If you are an IT administrator, you need to keep in mind that there is a limit to the number of times you can reactivate Windows on your computer. Moreover, if you don’t see any option to reactivate the license, and it is a work computer, you need to contact your organization’s tech support.

Option 3 – Try activating Windows 10 via mobile phone

Activating Windows 10 can also be done using your phone. Just note that you have to call Microsoft to do so.

• In the Start Search box, type in “Slui 4” and tap Enter.
• Next, select your country and click on Next.
• Keep the window open and call the toll-free number of the country you’re from.
• Afterward, a confirmation ID should be given by the automated system which you must take a note of.
• Finally, in the box on the window, type in the confirmation ID and click on the Activate button. That should do it.

A surprisingly large amount of things present at your home can and do interfere with your wi-fi signal making it weak so devices are dropping it, having trouble connecting, or being slow.

Hello and welcome to our latest article where we will take a look at all things that are present in a lot of homes but are very bad for your WI-Fi signal.

Bad router placement

Having a router in a bad position can have some really large effects on WI-Fi signal strength and its availability. Usually, we do not give great attention to where we are placing our router but it has been proved over and over again that being close to certain objects does indeed have a great influence on the wireless signal strength and performance.

So, what are these objects and bad positions where we could place the router and effectively kill his Wi-Fi capabilities?

Fish Tanks

Water will block all radio waves including Wi-FI signals and waves themselves, so having a router next to the aquarium or any large source of water is a bad idea. You should always look at water as something bad for your Wi-Fi and move your router away from it as far as possible.

Bookshelves

Paper is another story and example of the dampening effect on radio waves. Did you know that various patterns of paper are used in silent rooms and recording studios in order to eliminate sound reflection from surfaces? Well besides absorbing sound waves, the paper also absorbs Wi-Fi signals and if you have a large bookshelf with a lot of books packed one beside another you just have a great wall of signal absorbing.

Mirrors

The problem with mirrors is in their coating that goes over the glass in order to turn it into the mirror, that coating is metal and as such, it is absorbing signals in large amounts. If you have an old or high-quality mirror that has a silver coating things are even worse since silver will absorb even more waves than modern cheap ones.

TV

Yup, TV is also on this list and for a similar reason as a mirror, although TV does not have coatings of metal, they have something even worse: a large metal plating on the back. Metal plating is there to produce structural integrity of the TV set and provide it with shielding from electromagnetic waves and as such it will prevent Wi-Fi waves as well. Do not place the router behind your TV.

Things that influence signals in homes

Any kind of metal decoration

Now when we covered mirrors and TV because of the metal they have, we must take a look at the metal itself. Any kind of metal stuff that you might have like baskets, figures, statues, frames, etc will effectively block your signal.

Kitchen appliances and Home utilities

Kitchen appliances like refrigerators, microwaves, ovens, stoves, etc. along with home appliances and utilities like dishwashers, washing machines, dryers, etc are large metal objects enclosed in a metal cage that will block signals from spreading further and it is no secret that most kitchens have weaker Wi-Fi because of this reason.

Home gyms

This is a logical conclusion as to everything explained so far if you have a workout room or small gym at home it is probably filled with weights that are metal and have mirrors inside, all of that will interfere and block signals.

Things blocking your Wi-Fi that you have no easy control over

Walls

Thick walls will dampen signals, thick walls from bricks will dampen even more and concrete walls will kill it almost completely. Any kind of metal reinforcement wiring inside walls will reduce and kill signals as well.

Floors and ceiling

This is somewhat important if you have a floor beneath or under the room where is your router located, but for the same reason how walls are blocking your signal floor and ceiling can do it as well, especially since most of the time they are made of some stronger material like concrete with metal fence inside.

Heating systems

If you have a heating system that is composed of metal radiators with water inside, then in terms of Wi-Fi signal strength you have an aquarium but in a metal box, and as such it will greatly reduce signal strength.

Recently, a number of users reported seeing plain white icons on their “.docx” files instead of the Word icon. This kind of issue is mostly caused by a conflict with the default program settings in Windows which is why you may not see any Microsoft Word icon on your .docx files. So if you suddenly find that the Microsoft Word icon is either blank or missing and does not show properly on .doc and .docx document files of Office on your Windows 10 computer, then you can check out the potential solutions outlined below. Before you proceed, you can try to restart your computer as there are instances when a simple system restart can resolve some issues like this one. However, if it does not help, create a System Restore point first. This is to ensure that you can always undo the changes you are about to make in case something goes wrong. Once you have that covered, proceed to the following options.

Option 1 – Try to configure .docx files to open with “winword.exe”

You can try configuring the .docx files to open with the winword.exe in order to fix the problem.

• Right-click on a .docx file and select the “Open with…” option.
• After that, if a prompt appears with a message saying, “How do you want to open this file”, select the “More apps” option to proceed.
• Next, scroll down and check the checkbox that says, “Always use this app to open .docx files” option.
• Then click on the “Look for another app on this PC” link and choose the WINWORD.exe application from one of the following paths based on the installed Office version in your computer and click Open:
  • Word 2016 (64-bit): C:/Program Files/Microsoft Office/root/Office16
  • Word 2016 (32-bit): C:/Program Files (x86)/Microsoft Office/root/Office16

• Now check if you can now see the Word icon on the .doc or .docx files.

Option 2 – Try changing the default Word icon via Registry Editor

• Tap the Win + R keys to open the Run utility.
• Then type “Regedit” in the field and hit Enter to open the Registry Editor.
• Next, navigate to this path located in the left pane: HKEY_CLASSES_ROOTWord.Document.12DefaultIcon
• From there, double click on the default value at the right pane and based on the Word version you are using as well as the architecture (32 bit or 64 bit) and then copy-paste the corresponding value in the Value data box:
  • For Word 2016 (64-bit) keep it as C:/Program Files/Microsoft Office/root/Office16/wordicon.exe,13
  • For Word 2016 (32-bit) Keep it as C:/Program Files (x86)/Microsoft Office/root/Office16/wordicon.exe,13

• Once you’re done, tap Enter and then close the Registry Editor.
• Restart your computer and see if the problem’s fixed.

Option 3 – Try to rebuild the Icon cache

You may want to rebuild the Icon cache as it could also help fix the issue.

• Tap Win + E to open File Explorer and then click Folder Options and click Views to show Hidden System Files.
• After that, go to C:Users%username%AppDataLocal folder and look for a file named Iconcache.db and delete it.
• Next, go to C:Users%username%AppDataLocalMicrosoftWindowsExplorer.
• From there, look for the following files and delete them.
  • iconcache_32.db
  • iconcache_48.db
  • iconcache_96.db
  • iconcache_256.db
  • iconcache_1024.db
  • iconcache_1280.db
  • iconcache_1600.db
  • iconcache_1920.db
  • iconcache_2560.db
  • iconcache_exif.db
  • iconcache_idx.db
  • iconcache_sr.db
  • iconcache_wide.dd
  • iconcache_wide_alternate.db
• Restart your computer. This will purge and rebuild the icon cache.

Option 4 – Try fixing Office apps

Fixing the Office apps can help you resolve the Word icon issue. All you have to do is open Settings > Apps. From the app list, look for the Microsoft Office Desktop apps and select it and then click on the Advanced options and click Fix. After that, wait until the process is completed and restart your PC. However, if the problem still persists, repeat the steps again but this time, click on Reset instead of Fix.

Option 5 – Try to repair Office Installation

If the options given above didn’t work, you can try to repair the Office installation and see if it can fix the problem.

• Open Control Panel and click on Programs and Features.
• Next, right-click on the Office program that you want to repair which in this case is, Word.
• Select Change and click Repair > Continue. After that, Office will start to repair Microsoft Word.
• Wait until the process is done and then reboot your computer.

A lot of things can go wrong even when you’re only doing some simple operations or tasks on your computer and this is due to the fact that there are various small operations make up in order to perform the larger operations on your computer.

Google Chrome is the most used browser in the world with the most user downloads. Most users are using browsers how it is, open it up and just surf but Chrome offers more than just plain surfing. Here we are presenting you with some interesting features that most users do not use but should.

Use Omnibox to search inside websites

Chrome's Omnibox, also known as the address bar got its name because it can do much more than just search the internet. You already probably know that just by typing any word you will search the internet with Google or another search engine of choice.

You can also set specific keywords inside Chrome settings to tie them with specific websites, for example, you can tie the letter E with errortools, and then just by typing E windows error you will search term windows error on website errortools. There are some already predefined things and you can add anything you want so this is a great feature in order to speed up your work skipping part of actually opening the site.

Search the internet for selected text

On any webpage, you can simply select any text and right-click on it to get a new menu entry that will say search Google for "your selected text" and by clicking on it you will automatically search the net for the selected term.

Grouping tabs

When we surf the internet some of us tend to have plenty of open tabs and over time they can clutter and shrink in width making the surfing experience an unpleasant one.

Chrome has tab groups and you really need to start using them since you can organize much better all the tabs, even color-code them.

Search all open tabs

On top right part on title bar right next to minimize button there is small arrow pointing down, once you clik on it all opened tabs will be displayed by name as a listand by clicking on it you will automatically switch to it.

Change download location

Google Chrome has its default download destination but you can change that destination and even turn on option to be asked where you would like your download to be saved each time.

Live Captions

YouTube has cations for its videos but Chrome itself has live caption option in order to provide you with automatic AI captions for any type of video or audio on any website. If you are struggling with following what is being said try this awesome option.

Extensions

Using extensions in Chrome is awesome, specialy if extensions are usefull but if you go incognito they are not active. There is an option in Chrome to turn on the extensions even in incognito mode and even better, you can even choose which ones you want to be active, you do not need to turn all of them.

If you were having some problems with your internet connection and you tried to run the Internet Connections troubleshooter but it displays an error message instead that says, “The default gateway is not available”, read on as this post will show you what you can do to fix this error. The first thing you can do to fix this error is to restart your computer and then try to run the Internet Connections troubleshooter again. However, if you still see the same error message, then you might want to troubleshoot the problem further. You can try to install the Network driver or reinstall the Network adapter drivers. You could also verify the power saving mode or reset TCP/IP as well as disable the Firewall temporarily.

Option 1 – Try installing the Network driver

The very first thing you can do to resolve the error is to install the network driver. It is a common solution to this kind of problem and most users encounter it right after a fresh installation of Windows 10. So if you have done this, then you need to install the network driver so that the network adapters can start working. You can find the network driver in the motherboard CD. On the other hand, if you are using a laptop, you might have to use another computer or mobile to download the network driver from the manufacturer’s website.

Option 2 – Update the Network Adapter drivers

If the first option is not applicable to you since you already have network drivers in your computer, you might want to update the Network Adapter drivers by following these steps:

• Tap the Win + R keys to launch the Run window and then type in the “msc” command and hit Enter to open the Device Manager window.
• Under the Device Manager, you will see a list of drivers. From there, look for the Network Adapters and expand them.
• Then right-click on each one of the Network drivers and update them all.
• Restart your PC and see if it helped in fixing the BSOD error.

Note: If updating the network drivers didn’t help in fixing the “Windows could not find a driver for your network adapter” error, you can also try to uninstall the very same drivers and restart your Windows 10 PC. After that, the system itself will reinstall the drivers you just uninstalled. Alternatively, you can also download and install the drivers from the manufacturer’s website directly.

You could also try to reinstall the network adapter driver, refer to these steps:

• Open the Devices Manager from the Win X Menu.
• Then locate the device drivers and right-click on them to open the Properties.
• After that, switch to the Driver tab and click on the Uninstall Device button.
• Follow the screen option to completely uninstall it.
• Finally, restart your computer. It will just reinstall the device drivers automatically.

Option 3 – Try to verify power-saving mode

If you are using a Windows 10 laptop, then you should know that the Power Options panel plays an important role. So if you’re getting an error in your laptop, you have to check some settings that are related to the Power Saving mode. To do so, follow these steps:

• Open Control Panel and go to Hardware and Sound and click on Power Options.
• Next, click on the “Change plan settings” option of your selected plan and then click the “Change advanced power settings” option.
• After that, you should see the Power Options window, and here, expand the Wireless Adapter Settings and Power Saving Mode.
• Now make sure that the Maximum Performance option is selected. If it’s not, select it and save the changes you’ve made.

Option 4 – Try to reset the TCP/IP

As you know, the TCP/IP or the Internet Protocol is the most important thing if you want to use the internet on your computer. That’s why if it ends up getting corrupted, you need to reset the TCP/IP to fix the problem. To reset TCP/IP, refer to these steps:

• In the Windows start the search, type “command prompt” and right-click on Command Prompt from the search results.
• Then select the “Run as administrator” option to open Command Prompt with admin privileges.
• After that, execute this command: netsh int ip reset resettcpip.txt
• Once it’s done, exit Command Prompt and restart your computer and then check if the error is now fixed.

Option 5 – Temporarily disable Firewall

On the other hand, the error could also be due to the Firewall software installed on your computer. Thus, disabling them or any security software installed on your computer is always a good idea you can try when you’re not able to access the shared drive on your computer. There are times when you encounter problems like the error “The default gateway is not available” due to interference of antivirus or security programs. Thus, you have to disable both your antivirus program and Windows Defender Firewall for the meantime and check if it fixes the error or not

Computers viruses, worms, ransomware, etc. are kinds of malicious software that no user should take lightly. On several occasions, we have touched upon security steps that each user should take in order to protect its identity and data. Sadly sometimes even when all precautions are taken some malware can still slip through and wreak havoc. Today we are looking at some of the worst or the best, depending on your view that has indeed wreaked plenty of havoc.

10 worst computer viruses in history

In the list of the 10 most famous computer viruses below, we show the costs, dates, reach, and other key facts. First a note about terms: we use the words “virus” and “worm” interchangeably because most readers search for them that way. But there’s a subtle difference that we explain after the list.

1. Mydoom – $38 billion

The worst computer virus outbreak in history, Mydoom caused estimated damage of $38 billion in 2004, but its inflation-adjusted cost is actually $52.2 billion. Also known as Novarg, this malware is technically a “worm,” spread by mass emailing. At one point, the Mydoom virus was responsible for 25% of all emails sent. Mydoom scraped addresses from infected machines, then sent copies of itself to those addresses. It also roped those infected machines into a web of computers called a botnet that performed distributed denial of service (DDoS) attacks. These attacks were intended to shut down a target website or server. Mydoom is still around today, generating 1% of all phishing emails. That’s no small feat considering the 3.4 billion phishing emails sent each day. By that figure, Mydoom has taken on a life of its own, infecting enough poorly-protected machines to send 1.2 billion copies of itself per year, 16 years after its creation. Though a $250,000 reward was offered, the developer of this dangerous computer worm was never caught. Wondering what makes the world’s most secure computers so safe?

2. Sobig – $30 billion

The 2003 Sobig computer virus is actually another worm. It is second only to the Mydoom virus in its scope. The $30 billion figure is a worldwide total, including Canada, the U.K., the U.S., mainland Europe, and Asia. Several versions of the worm were released in quick succession, named Sobig.A through Sobig.F, with Sobig.F being the most damaging. This cybercriminal program masqueraded as legitimate computer software attached to emails. It disrupted ticketing at Air Canada and interfered with countless other businesses. Despite its widespread damage, the creator of the successful bug was never caught.

3. Klez – $19.8 billion

Klez is a close third on the list of the worst computer viruses ever created. With nearly $20 billion in estimated damages, it infected about 7.2% of all computers in 2001, or 7 million PCs. The Klez worm sent fake emails, spoofed recognized senders and, among other things, attempted to deactivate other viruses. As with other viruses and worms, Klez was released in several variants. It infected files, copied itself, and spread throughout each victim’s network. It hung around for years, with each version more destructive than the last. Windows has come a long way since most of the computer viruses on this list hit the web. Thankfully, built-in protection with Microsoft Defender is always on the watch.

4. ILOVEYOU – $15 billion

The year 2000’s ILOVEYOU virus worked by sending a bogus “love letter” that looked like a harmless text file. Like Mydoom, this attacker sent copies of itself to every email address in the infected machine’s contact list. Shortly after its May 4 release, it had spread to more than 10 million PCs. The virus was created by a college student in the Philippines named Onel de Guzman. Lacking funds, he wrote the virus to steal passwords so he could log into online services he wanted to use for free. He reportedly had no idea how far his creation would spread. This virus is also known as Loveletter. Need to up your remote work security game before there’s another entry on the list of most deadly computer viruses?

5. WannaCry – $4 billion

The 2017 WannaCry computer virus is ransomware, a virus that takes over your computer (or cloud files) and holds them hostage. The WannaCry ransomware ripped through computers in 150 countries, causing massive productivity losses as businesses, hospitals, and government organizations that didn’t pay were forced to rebuild systems from scratch. The malware raged like wildfire through 200,000 computers worldwide. It stopped when a 22-year-old security researcher in the U.K. found a way to turn it off. Computers with out-of-date operating systems were hit especially hard. That’s why security experts always recommend updating your systems frequently.

Ransomware strikes again

In September 2020, one of the potentially largest computer virus attacks in medical history hit Universal Health Services. The U.S. hospital chain, which has more than 400 locations, was reportedly struck by damaging ransomware. The attack forced the cancellation of surgeries and made healthcare workers switch to paper records.

6. Zeus – $3 billion

The Zeus computer virus is an online theft tool that hit the web in 2007. A whitepaper by Unisys three years later estimated that it was behind 44% of all banking malware attacks. By then, it had breached 88% of all Fortune 500 companies, 2,500 organizations total, and 76,000 computers in 196 countries. The Zeus botnet was a group of programs that worked together to take over machines for a remote “bot master.” It originated in Eastern Europe and was used to transfer money to secret bank accounts. More than 100 members of the crime ring behind the virus, mostly in the U.S., were arrested in 2010. It’s not as prominent today, but some of the virus’ source code lives on in newer botnet viruses and worms. Zeus caused documented damage of $100 million. But the real cost in terms of lost productivity, removal, and undocumented theft is undoubtedly much higher. A $3 billion estimate, adjusted for inflation, puts this virus at a cost of $3.7 billion in today’s dollars.

7. Code Red – $2.4 billion

First observed in 2001, the Code Red computer virus was yet another worm that penetrated 975,000 hosts. It displayed the words “Hacked by Chinese!” across infected web pages, and it ran entirely in each machine’s memory. In most cases it left no trace in hard drives or other storage. Financial costs are pegged at $2.4 billion. The virus attacked websites of infected computers and delivered a distributed denial of service (DDoS) attack on the U.S. White House’s website, www.whitehouse.gov. In fact, the White House had to change its IP address to defend against Cod Red. Can your printer get a virus? See our cool infographic: The State of Printer Security

8. Slammer – $1.2 billion

The SQL Slammer worm cost an estimated $750 million across 200,000 computer users in 2003. This computer virus randomly selected IP addresses, exploiting vulnerabilities and sending itself on to other machines. It used these victim machines to launch a DDoS attack on several internet hosts, significantly slowing internet traffic. The Slammer worm hit banks in the U.S. and Canada especially hard, taking ATMs offline in many locations. Customers of Toronto’s Imperial Bank of Commerce found themselves unable to access funds. The attack reared its ugly head again in 2016, launching from IP addresses in Ukraine, China, and Mexico.

9. CryptoLocker – $665 million

Thankfully, ransomware attacks like the 2013 CryptoLocker virus have dipped since their 2017 peak. This malware attacked upwards of 250,000 machines by encrypting their files. It displayed a red ransom note informing users that “your important files encryption produced on this computer.” A payment window accompanied the note. The virus’ creators used a worm called the Gameover Zeus botnet to make and send copies of the CryptoLocker virus. According to a report by security firm Sophos, the average ransomware attack costs a business $133,000. If we estimate that CryptoLocker hit 5,000 companies, that would put its total cost at $665 million. Where will cybersecurity go next? See our guide: The Future of Cybersecurity

10. Sasser – $500 million

The Sasser worm was written by a 17-year-old German computer science student named Sven Jaschan. He was arrested at the age of 18 in 2004 after a $250,000 bounty was posted for the computer virus’ creator. A friend of Jaschan’s tipped authorities that the youth had penned not only the Sasser worm but also the damaging Netsky.AC attack. Jaschan was given a suspended sentence after it was found he was a minor when he wrote the malware. The Sasser worm crashed millions of PCs, and though some reports put damages at $18 billion, the relatively low infection rate suggests a more likely cost of $500 million. Other notable viruses The top 10 worst computer viruses above are just the ugly tip of a gargantuan digital iceberg. With a million new malware programs popping up every 3 years, we may miss the forest for a few outstanding trees. Here are just a few more viruses that have wreaked havoc over the years: Mimail: This worm tried to harvest data from infected machines to launch a string of DDoS attacks, but was relatively easy to remove. Yaha: Yet another worm with several variants, thought to be the result of a cyber-war between Pakistan and India. Swen: Written in C++, the Swen computer worm disguised itself to look like a 2003 OS update. Its financial cost has been pegged at $10.4 billion, but not reliably. Storm Worm: This worm showed up in 2007 and attacked millions of computers with an email about approaching bad weather. Tanatos/Bugbear: A 2002 keylogger virus that targeted financial institutions and spread to 150 countries. Sircam: A computer worm from 2001 that used counterfeit emails with the subject line, “I send you this file in order to have your advice.” Explorezip: This worm used fake emails to spread to every machine on thousands of local networks. Melissa: The most dangerous computer virus in 1999, Melissa sent copies of itself that looked like NSFW pics. The U.S. FBI estimated cleanup and repair costs at $80 million. Flashback: A Mac-only virus, Flashback infected over 600,000 Macs in 2012 and even infected Apple’s home base in Cupertino, Calif. In 2020, there’s now more malware on Macs than on PCs. Conficker: This 2009 virus still infects many legacy systems and could do significant damage if it ever activates. Stuxnet: This worm is reported to have destroyed Iranian nuclear centrifuges by sending damaging instructions.

Recently, a number of users reported that they were not able to use the “Run as administrator” context menu option when they tried using it or opening a program with administrator privilege. If you are one of these users facing this problem, then you’ve come to the right place as this post will guide you in fixing this issue. At the time of writing, it isn’t clear what the cause of the issue is but there are potential fixes you can try to fix the problem. You can try turning on the User Account Control or clean up the Context Menu items change the Group Membership. On the other hand, you can also perform both SFC and DISM scans via Command Prompt or troubleshoot the problem in a clean boot state as it is possible that some third-party programs are the ones that are causing the problem. You could also run an anti-malware scan using Windows Defender or your antivirus program.

Option 1 – Try to turn on the User Account Control

When you open a program with administrator privilege, the User Account Control or UAC prompt will pop up asking you to confirm the permission. However, if you have disabled the User Account Control by mistake or some malware has disabled it, then it’s no wonder why the “Run as administrator” option is not working. Thus, you need to check if UAC is turned on or not. All you have to do is go to the User Account Control settings.

Option 2 – Try changing the Group Membership

• First, you need to sign in with your administrator account or ask your administrator to sign in for you. So if you only have a Standard User account, you have to add that account to the Administrators group.
• In the taskbar search box, type “netplwiz” and check the search results.
• From there, select your user account and click the Properties button.
• After that, go to the Group Membership tab and select Administrator.
• Now click on the Apply and OK buttons to save the changes made and then sign in to your computer again and see if the “Run as administrator” option is working or not.

Option 3 – Try to create a new Administrator User account

If you have a standard account, you can try creating a new account but this time, you create an administrator user account and then see if you can now use the Run as administrator option or not. Note that you have to sign in with your main account before you can create an admin account.

Option 4 – Run the DISM tool

You can run the DISM tool as well to help fix the problem with the “Run as administrator” option. Using this built-in tool, you have various options such as the “/ScanHealth”, “/CheckHealth”, and “/RestoreHealth”.

• Open the Command Prompt with admin privileges.
• Then type in the following commands and make sure to hit Enter right after you type each one of them:
  • Dism /Online /Cleanup-Image /CheckHealth
  • Dism /Online /Cleanup-Image /ScanHealth
  • exe /Online /Cleanup-image /Restorehealth
• Do not close the window if the process takes a while as it will probably take a few minutes to finish.

Option 5 – Perform a System File Checker scan

The SFC or System File Checker scan could detect and automatically repair damaged system files that could be causing the problem with the “Run as administrator” option on your Windows 10 computer. SFC is a built-in command utility that helps in restoring corrupted files as well as missing files. It replaces bad and corrupted system files with good system files. To run the SFC command, follow the steps given below.

• Tap Win + R to launch Run.
• Type in cmd in the field and tap Enter.
• After opening Command Prompt, type in sfc /scannow and hit Enter.

The command will start a system scan which will take a few whiles before it finishes. Once it’s done, you could get the following results:

1. Windows Resource Protection did not find any integrity violations.
2. Windows Resource Protection found corrupt files and successfully repaired them.
3. Windows Resource Protection found corrupt files but was unable to fix some of them.

• Once done, restart your computer.

Option 6 – Put your computer in a Clean Boot State

You can also troubleshoot the problem in a Clean Boot state. It could be that there are some third-party applications in your computer that are preventing you from using the “Run as administrator” option and to isolate this possibility, you need to boot your computer in a Clean Boot State and then try to use the Run as administrator again. Putting your computer in this state can help you identify which program is the culprit and thus isolates the problem. In a Clean Boot state, your computer will start using only the pre-selected minimal set of drivers and startup programs. Note that you have to disable and enable one process at a time.

• Log onto your PC as an administrator.
• Type in MSConfig in the Start Search to open the System Configuration utility.
• From there, go to the General tab and click “Selective startup”.
• Clear the “Load Startup items” check box and make sure that the “Load System Services” and “Use Original boot configuration” options are checked.
• Next, click the Services tab and select the “Hide All Microsoft Services” check box.
• Click Disable all.
• Click on Apply/OK and restart your PC. (This will put your PC into a Clean Boot State. And configure Windows to use the usual startup, just simply undo the changes.)
• After you’ve set your computer into a Clean Boot State, try to check if the error is now fixed and that you can now view the Properties.

Option 7 – Try scanning your computer using Windows Defender

As mentioned, if your computer was recently infected with some malware, it is possible that the malware changed the User Account Control settings which is why you’re not able to use the Run as administrator option. Thus, you need to scan your computer using Windows Defender.

• Tap the Win + I keys to open Update & Security.
• Then click on the Windows Security option and open Windows Defender Security Center.
• Next, click on Virus & threat protection > Run a new advanced scan.
• Now make sure that Full Scan is selected from the menu and then click the Scan Now button to get started.
