4 Methods of Fixing Error Code 49

Error Code 49 – What is it?

Error Code 49 is a common device driver error that users encounter on any Windows 2000 and later operating system versions.

The error occurs when the connected peripheral devices fail to function properly due to an overload of the system hive’s size.

The error when prompted pops up on your screen with the following message:

"Windows cannot start new hardware devices because the system hive is too large (exceeds the Registry Size Limit). (Code 49)”

The error causes unattached devices to be displayed on the system hive list.

Solution

driverfix boxError Causes

Error Code 49 mainly results from problems in Windows registry system files; the system hive in the Windows registry exceeds its size limit.

The system hive is part of the Windows registry and it is where files regarding devices are contained along with user preferences and applications.

The devices will not work until the system hive size is brought back to normal levels.

Further Information and Manual Repair

There are several ways you can use to fix your error code. Here are the following.

Method 1 – Uninstall unused devices

One of the best ways to address the error code is to uninstall the unused devices which are listed on your computer’s system hive. To do this:

  • Log in using an Administrator account
  • Click the Start button and then click ‘Run’
  • In the box, enter the command:
  • "set devmgr_show_nonpresent_devices=1 cd%SystemRoot%System32 exit"
    and click enter
  • Open Device Manager, click ‘View’, and then choose ‘Show hidden devices’ to see unused devices.
  • When you can see the list, click on the device you want to uninstall by selecting the ‘Driver’ tab and then select ‘Uninstall’.
  • After uninstall is complete, restart your computer.

Method 2 – Use System Restore

If the error still persists, you can use system restore to eliminate the problem. Here is how you can do so:

  1. Log in using an Administrator account
  2. Click ‘Start’ button and select All Programs > Accessories > System Tools > System Restore
  3. Click ‘Restore my computer to an earlier time’ and click ‘Next’
  4. Select the last Windows restore point from the ‘On this list, click a restore point’ list, and click ‘Next’
  5. Click ‘Next’ on the confirmation window to proceed
  6. Restart your PC after restoration is complete

By restoring the system via a last saved system checkpoint, you can obtain undamaged Windows system files that can help avert the error code.

Method 3 – Manually uninstall and reinstall the device driver

If using system restore does not work in resolving the error code either, you may have to resort to manually uninstalling and then reinstalling the device driver causing the problem.

This would be necessary since the remaining incomplete files due to a partial removal or installation of programs is what results in the error code. By uninstall and reinstalling the device driver program, it would lead to the completion of the files.

You can do this by firstly logging in as Administrator and open Device Manager. Select the device that is causing the problem and double click it and make sure that the peripheral is connected properly to the PC.

Upon opening, click on the ‘Driver’ tab and then select ‘Update Driver’. Make sure to refer to the system documentation that you received with your PC or computer to check for the motherboard details and driver specifics.

Method 4 – Use software to automatically download the driver

Manually uninstalling and reinstalling the driver will do the trick; however, it may be time-consuming, especially when you would have to resort to your hardware user manual.

Therefore, using a program such as DriverFIX can save you a lot of time and frustration in having your device work properly on your computer.

DriverFIX, with its user-friendly approach to help you fix your PC issues, comes with an integrated database that detects which drivers you need to reconfigure within just a few seconds and downloads it automatically.

Impacts & consequences Of Ransomware
From the various report, it is now clear that no one is prone to Ransomware attacks. Cyber-criminals never target any specific field of the user workgroup for this Ransomware attack. But in past few years, it has hugely affected home users, businesses, organizations. We can say, Ransomware victims come in all shapes & sizes. Many business owners think that they will never be attacked by Ransomware crooks because their business is not so big. But that’s not true. A huge proportion of Ransomware attacks happened in small sector businesses because of their weak security resistances.

Some leading negative consequences of Ransomware attacks faced by almost every victim are:

  1. Permanent or temporary loss of proprietary or sensitive information.
  2. Lots of trouble in performing regular operations.
  3. Huge financial losses sustain for restoring up your files and systems.
  4. Latent harm to the reputation of an organization.
  5. Even making the Ransom payment doesn’t guarantee the safe releasing of your encrypted files.
  6. Attackers get the victim’s money along with their banking details.
  7. Getting the decrypting files doesn’t mean malware infection has completely been removed.
Ransomware put a tremendous impact on disturbing business operations and in the end, leads to data loss situations.

Here are some huge impacts of Ransomware attacks on business are:

  1. Damage or loss of all the crucial information
  2. In the Ransomware post-attack period Business disrupts a lot.
  3. Destruction of hostage data, file, and system.
  4. Business downtime
  5. Victimized company’s reputation dropdown
  6. Productivity loss
Apart from the ransom, the cost of downtime because of restricted system access will bring major concerns. It’s a fact that due to downtime victims may has to pay a cost of ten thousand dollars daily. As, Ransomware is becoming more and more widespread, so all companies require to brush up on their annual cyber-security goals. Moreover, approach for some appropriate implementations of Ransomware recovery plans and commit sufficient funds in their IT budgets for cyber-security resources. Among the most effective impact of Ransomware, “data encryption” is very hard to deal with. Meanwhile, this victim is completely restricted to access any of their encrypted data. The only way for unlocking these encrypted files is through the decryption key which only belongs to hackers. Many times, the decryption key is given to the organization, after the payment of the ransom. But there are also some cases when data is not handover to the victim, even after the ransom payment. The main risk that generates with “operational impact of Ransomware” is on the businesses. Can you just imagine, what will happen if all of a sudden entire services or processes of your business halt down?

Well, this dreadful Ransomware threat is so impactful that it can:

  1. Close down the entire plant
  2. Freeze manufacturing control system
  3. Make other backlogs
All the damages that occur due to downtime can be a major one and can have so many consequences. A well-organized strategy of backup and recovery will not certainly make the Ransomware attack painless. As this takes an extensive amount of money and time for data restoration.

Apart from that, the decision of recovering your system using the backup moreover depends on three things:

  1. First the amount of data loss that is considered acceptable by your business or organization.
  2. Up to how extent, the impact of Ransomware has spread
  3. How fast the Ransomware attack was spotted.
However, in many cases, data gets so encrypted that you can’t revert back to the restore point. At that time external backup is considered the best option. Among the wide-reaching impact of Ransomware “Data loss” is the most effective one.  As it starts from little disruption and leads to permanent business failure. Sometimes data loss in a Ransomware attack leads to disclosure of all your confidential information which ends up in fines and lawsuits. Attackers always look for backup files and folders after encrypting your system data. So that user can’t retrieve their corrupted file from the backup. Such dreadful activities make this Ransomware threat so profitable and effective. Victims don’t have any choice left either they have to pay the ransom or they have to face their risk of data loss.

Fix Chassis Intruded…Fatal Error…System Halted
When you encounter an error message that says, Chassis Intruded…Fatal Error…System Halted on your monitor then it indicates that the Chassis or the cabinet that holds the CPU, GPU, motherboard, and many more is open. It is a security feature offered by OEMs wherein a connector that is found in the motherboard can detect if the chassis component has been replaced or removed. There are a few OEMs that offer onboard speaker or PC chassis speaker which goes off in this kind of situation. Obviously, the problem has something to do with the hardware and in most cases, you have to put the jumper back on the motherboard with the pin-labeled chassis signal and ground. There are times when some OEMs offer a simple switch that is armed automatically when you properly close the chassis. Thus, you need to check if this switch has something to do with the error. If there is no switch or if it doesn’t resolve the issue, although you may be able to get into Windows with a warm boot, the normal Windows boot won’t really work unless you fix the problem. It is rather false positive and has something to do with the RTC RAM state or the BIOS. You might need to completely disable the Chassis intrusion feature to fix the error. Refer to the suggestions given below to try and fix the “Chassis Intruded, Fatal Error … System Halted” error.

Option 1 – Try to clear CMOS

You can easily clear CMOS by shorting two pins which can be found side by side on the motherboard. Keep in mind that it may vary from OEM to OEM although the basics are still the same to clear CMOS. In addition, you might also have to download the manual from the OEM’s website so that you’ll know its exact location.

Option 2 – Try booting into the BIOS

You can also try booting into the BIOS. All you have to do is tap either the DEL or F2 keys to get there. Note that everything will be set back to their default setting after you reset the CMOS.

Option 3 – Try disabling Chassis intrusion

In this option, you have to look for the Chassis intrusion feature in your BIOS. It might be located under security. From there, disable it and check if the problem’s fixed.

Option 4 – Try to reconfigure the BIOS

Once you have disabled the Chassis feature, you need to reconfigure the BIOS the way you expect it to be or to what it was before the reset.

System32 Folder Keeps Popping up at Startup
The System32 folder contains vital configuration and information that are essential to the operating system. It is located inside the “Windows” folder and it consists of important DLL files as well as executable files. You probably have noticed some errors that have the “System32” word in them but that does not necessarily mean that the System32 folder is the one that triggers them as these kinds of errors have only occurred when some important files are corrupted or missing. Some users recently reported that each time they start their computers, the System32 folder will automatically open up in the File Explorer. If you encounter the same problem, read on as this post will guide you on what to do to fix it. This kind of issue is most likely caused by service or application interference – it is possible that there is a third-party application installed in your computer or a Windows service that triggers the System32 to pop up during startup. It is also possible that this is a result of system modification. Thus, you need to identify the third-party program or restore your computer to its previous state.

Option 1 – Put your computer in a Clean Boot State

As pointed out, it is possible that some third-party program or service is the one that’s behind the problem. To isolate this possibility and to identify the culprit, you have to put your computer into a Clean Boot State. To do so, follow the steps below.
  • 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 putting your PC in a Clean Boot State, try creating a system restore point and see if the problem still occurs. Clean Boot troubleshooting is designed to help you isolate the problem. For you to execute a clean boot troubleshooting, you must do a couple of actions (the steps given above) and then restart your PC after every action. You might have to disable one third-party app after the other to really isolate the issue. And once you’ve narrowed down the problem, you can either disable the third-party app that’s causing the problem or remove it. Note that you must switch your PC back into the Normal Startup mode after you’re done troubleshooting the problem. Here’s how you can do it:
  • From the “Start” menu, go to System Configuration.
  • After that, switch to the General tab and click the option for “Normal Startup”.
  • Next, go to the Services tab and clear the checkbox for “Hide all Microsoft services”.
  • Then find and click “Enable all” and if prompted, you have to confirm.
  • Afterward, go to the Task Manager and enable all the Startup programs and confirm the action.
  • Restart your PC when prompted.

Option 2 – Perform System Restore

  • First, press the Win + R keys to open the Run dialog box.
  • After that, type in “sysdm.cpl” in the field and tap Enter.
  • Next, go to the System Protection tab then click the System Restore button. This will open a new window where you have to select your preferred System Restore point.
  • After that, follow the on-screen instructions to finish the process and then restart your computer and check if the problem is fixed or not.

Option 3 – Run System File Checker scan

You might also try running the System File Checker or SFC scan to fix the issue. System File Checker is a command utility built into your computer that helps restore corrupted files and missing files. Refer to the following steps to run it:
  • Hit the Win + R keys to launch Run.
  • Type in cmd in the field and tap Enter.
  • After opening Command Prompt, type in sfc /scannow
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.
 Restart your computer and see if the System32 folder still pops up at startup or not.

10 Worst Computer Viruses in history
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.

viruses10 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? See the Tech@Work guide: Upgrade to the World's Most Secure and Manageable PC

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? See our guide: How to Work Remotely and Securely

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.

Fix Update components must be repaired
Recently, a lot of users reported having an issue with Windows Update. According to these users, they got an error message saying, “Windows Update components must be repaired” after they run the Windows Update troubleshooter. So if you are also facing this issue then you’ve come to the right place as this post will guide you in fixing this problem. There are various suggestions you can check out to fix this problem – you can try running the Windows Update troubleshooter again but this time, in a Clean Boot State or you could also run System File Checker or the DISM tool to repair corrupted Windows Update files or reset the Windows Update components. For more information, refer to the given options below.

Option 1 – Run the Windows Update troubleshooter in a Clean Boot State

Repairing the “Windows Update components must be repaired” error is not that complicated. One of the things you can try is to run the Windows Update troubleshooter again but this time, in a Clean Boot State. Refer to the steps below to get started.
  • 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.

  • Now try to run the Windows Update troubleshooter again and see if the error is fixed or not.

Option 2 – Try to run System File Checker

If the Windows Update troubleshooter still failed to fix the problem, you can run System File Checker instead. It 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
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.

Option 3 – Run the DISM tool

Running the DISM Tool helps in repairing the Windows System Image as well as the Windows Component Store in Windows 10. 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.
Note: If it happens that the Windows Update client is broken, you need to run the following command to repair it then restart your PC and click on Update once again.
DISM.exe /Online /Cleanup-Image /RestoreHealth /Source:C:RepairSourceWindows /LimitAccess

Option 4 – Delete the contents in the Software Distribution folder and Catroot2 folder

You can also delete the contents in both the Software Distribution and Catroot2 folders as it could potentially fix the “Windows Update components must be repaired” error.
  • Open the WinX Menu.
  • From there, open Command Prompt as admin.
  • Then type in the following command – don’t forget to hit Enter right after typing each one of them.
net stop wuauserv net start cryptSvc net start bits net start msiserver
  • After entering these commands, it will stop the Windows Update Service, Background Intelligent Transfer Service (BITS), Cryptographic, and the MSI Installer
  • Next, go to the C:/Windows/SoftwareDistribution folder and get rid of all the folders and files thereby tapping the Ctrl + A keys to select them all and then click on Delete. Note that if the files are in use, you won’t be able to delete them.
After resetting the SoftwareDistribution folder, you need to reset the Catroot2 folder to restart the services you just stopped. To do that, follow these steps:
  • Type each one of the following commands.
net start wuauserv net start cryptSvc net start bits net start msiserver
  • After that, exit Command Prompt and restart your computer, and then try to run Windows Update once more.

Permission to view object security properties
In an operating system, it is ideal for an administrator to have permission to access all the folders and files. However, there are times when you try to access the security settings or attempt to view the properties of a file, you could encounter an error saying, “You do not have permission to view this object’s security properties, even as an administrative user”. This kind of error may be caused by several reasons. For one, if your computer is infected with a virus or malware which might have caused some changes to the concerned folder or file. It could also occur if a program or service is using the folder or file simultaneously which explains why you’re not able to access the system. It could also be that the folder or file might have been owned by a user account that no longer exists or you might not have the permissions to view the targeted folder or file even though you’re logged in as administrator. To fix the “You do not have permission to view this object’s security properties, even as an administrative user” error, here are some options that might help.

Option 1 – 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’re preventing you from accessing security settings or properties of a file and to isolate this possibility, you need to boot your computer in a Clean Boot State and then try installing the program 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 2 – Try booting your computer into Safe Mode and delete inactive users

Aside from the Clean Boot State, you can also reboot your computer in Safe Mode and then delete all the inactive users. There are instances when the folder was created or owned by a user account that’s either deleted or inactive now and so you need to get rid of these inactive user accounts to resolve the error.
  • First, boot your computer in Safe Mode.
  • Then right-click on the concerned folder or file and select Properties.
  • Next, select Advanced in the Security tab and click on Add.
  • A new window will appear and from there, click on “Select a principal”.
  • And then type the name of the user to who you wish to give permissions in the “Enter the object name to select” box.
  • Now select Check Names and this would resolve the user name.
  • After that, click OK to save the settings. This will close the window and take you back to the previous one.
  • Next, from the drop-down menu, change the Type to Allow and select the Full Control checkbox.
  • Click OK to save the changes made and then restart your computer in a normal mode.

Option 3 – Try to take ownership of the folder or file

Another thing you can do to fix the problem is to take ownership and force the system into giving permissions to the Administrator. How? Refer to these steps:
  • Type “command prompt” in the Windows Search bar and then right-click on the relevant search result and select “Run as administrator”.
  • After that, if a User Account Control or UAC prompt appears, just click on Yes to proceed.
  • Next, type and enter this command: TAKEOWN /F <path>
  • Note that the <path> is the location of the folder or file in File Explorer.
  • Now type and enter this second command: ICACLS <path> /grant administrators:F
  • Finally, once the command has been executed, restart your computer and then see if you can now access the folder or file.

Option 4 – Try scanning your computer using Windows Defender

As mentioned, the error when accessing the security settings or properties of a folder or file might be due to a virus or malware. It could be that it had made some modifications that prevents you from accessing security settings or properties. To eliminate it, you have to scan your computer using security programs like 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.
