Many times we were talking and writing here on Errortools.com about security, privacy, hacking, identity theft, etc. We tried to raise important security questions and I hope I have managed to at least shed some light and change maybe some bad behaviors for some, helping them embrace better routines about their security on their PC.
In this light, I will today present you with one neat and awesome piece of software, a password manager worth your time and money (if you want premium features): BitWarden.
What BitWarden offers?
The first thing that it offers is the completely free basic plan, granted BitWarden is not an open-source project nor completely free but it has an unlimited free basic plan that will cover 90% of user needs. There is also a free basic unlimited plan for Organizations letting you and one more user share files and other stuff via BitWarden making it a cool option if you need it.

As you know, the USB security keys are a secure medium to validate a lot of components in a computer. They can be used to log in to Windows 10. Now with the advancement of APIs, you can authenticate across the website as well using the same key. However, there are times when it may not work and it could be caused by several factors. It could be due to corrupted or incompatible drivers or it could also be due to compromised integrity of the key, and many more.
So if you happen to encounter an issue with the USB security key on your Windows 10 computer, then there are several potential fixes you can try. You can try toggling the Internet Options settings or reinstall the respective USB drivers. You could also try changing the PIN of the security key or disable the antivirus program on your computer or troubleshoot the web browser. Refer to the potential fixes provided below to fix the problem.
Option 1 – Try to toggle the settings of the Internet Options
In the Windows Search box, search for Internet Options to open it.
Next, go to the Security tab and drag the security slider to the lowest possible security for all the given zones.
After that, click on OK to save the changes made and close the Internet Options.
Note that this option is only a temporary measure as it can make your computer vulnerable. Make sure to press the Reset all zones to default level button.
Option 2 – Try to update or reinstall the respective drivers
If updating the drivers of the device did not fix the problem with the USB security key, you can try to update or reinstall the Universal Serial Bus Controller drivers instead of using the Device Manager. Refer to the following steps:
First, click the Start button and type “device manager”.
Then click on the “Device Manager” from the search results to open it.
From there, look for the “Universal Serial Bus controllers” option and then right-click on each one of the USB drivers and select the Update Driver from the menu.
Note: If it is a regular USB drive, then it will be listed as a USB Mass Storage Device but if you have a USB 3.0 device, then look for a USB 3.0 Extensible Host Controller.
Restart your PC and then click the “Search automatically for updated driver software” option.
Note: If updating the USB Controller drivers didn’t work, you can try to reinstall them instead.
Option 3 – Try to change the PIN of the security key
If the first two options didn’t work, you can try changing the PIN of the security key. There are instances when the PIN for the security key might have been corrupted. Thus, resetting it can help you resolve the problem.
Option 4 – Temporarily disable Firewall and third-party antivirus
Firewall and antivirus programs are known to block the proper functioning of the USB security key. Thus, your antivirus or firewall programs might be the reason why you can’t download anything on your Windows 10 computer. To isolate the issue, you need to temporarily disable both the Firewall and antivirus programs and then check if you can now download anything from the internet. Do not forget to enable them again as disabling them can leave your computer vulnerable to cyber threats.
Option 5 – Try to troubleshoot the web browser
Troubleshooting your web browser can also help you fix the USB security key problem. You can do that by checking if your web browser supports the security key and you can do that by checking on the official website of your browser. You can also try to update your web browser to its latest version but if it didn’t help, you can try to reinstall it or switch to another web browser.
Some users trying to upgrade from Windows 7 or Windows 8/8.1 reported experiencing installation rollback with error code 0x80070004. This error normally appears when the Computer Name is set to names that can’t be used for the computer. It’s also possible this error occurs if users or program files folder were redirected to a different partition.
Solution
Error Causes
The Error code 0x80070004 on Windows 10 is normally caused if any of the following were used as the Computer Name and the user tried to upgrade to Windows 10:
System (or SYSTEM)
SELF
LOCAL
Network
Failure to fix this error message might result in others, including error code 0xc0000001.
Further Information and Manual Repair
If you don’t solve this error, you won’t be able to upgrade from Windows 7 or Windows 8/8.1 to Windows 10. Note that this error will continuously bring you back to the original OS unless fixed.
Please note that if you’re not confident in doing these steps, you might want to consider seeking the help of an expert or using an automated tool that will help fix this.
Here are a few methods to try.
Method 1: Check and Change the Computer Name
The most common cause of this error is if your computer uses any of the following reserved names:
LOCAL
System (or SYSTEM)
Network
SELF
These reserved names are not meant to be used as computer names. If this is what your computer uses and you try to upgrade to Windows 10, you will surely get this error. Check your computer name and if you see any of the reserved names, change it right away.
Changing Computer Name in Windows 8.1
If you’re trying to upgrade from Windows 8.1, you can change the name of the computer by following these steps:
Step 1:Open the Start menu then simply type “rename computer”. After that, choose “Rename this computer”
Step 2: A dialog box will open. Just click the “Change” button
Step 3: A new dialog box will open. Type the new name. Click Apply then Ok.
Changing Computer Name in Windows 7
If you’re trying to upgrade from Windows, you can follow the steps below to change the name of your computer.
Step 1:Go to the Start menu then on the Computer section, right-click the mouse and choose “Properties”.
Step 2:A new dialog box will appear. Go to “Computer name, domain, and workgroup settings” then click “Change settings”. In case you’re asked for administrative access, make sure to grant it.
Step 3:Find the “Computer Name” tab then click “Change”
Step 4:Change the computer name and click Ok.
Method 2: Fix the “Users” directory issue
If the first method doesn't work, it probably means the computer name isn’t the cause of this error. Another reason why users experience Error code 0x80070004 when upgrading to Windows 10 is if the “Users” directory was relocated. So, when you try upgrading to Windows 10, the installer wasn’t able to find the user profiles on the “%systemdrive%”, where the current operating system is installed.
If you changed or moved any of the Users, Program Data, or Program Files folders, this will cause the error. Before you upgrade to Windows 10, you might be required to reset or reinstall your current operating system (Windows 7 or Windows 8.1).
If you haven’t made any changes or haven’t moved any of the mentioned folders, there’s a great chance that your users' profiles are corrupted. You can also reinstall your current operating system. However, you might want to check for the corrupter user profile first. To do this, follow the steps below:
Step 1:Go to the Start menu and type System
Step 2:Click System then go to the Advanced tab
Step 3:Go to Settings, which you’ll find under User Profiles
On the Users Profiles, make a copy of all the accounts somewhere. Sign out from the current user account then try logging in back using the accounts you’ve copied. For each account, you get an error, delete it. However, make sure that you don’t delete the UpdateUser and Administrator account ever.
After this is done, try upgrading your operating system to windows 10 again.
Method 3: Try a trusted and secured Automated Tool
If the above methods still not useful, you might want to rely on an automated tool. Find a secured and trusted tool. It will help fix this issue.
If the Task Manager is either blank or is not showing processes on your Windows 10 computer, then here are a few things you can do to resolve this issue. This kind of problem can occur due to some system file corruption or some malware infection in the system.
Here are some suggestions you can try to resolve the problem with the Task Manager on your Windows 10 PC.
Option 1 – Try restarting your computer
The most common and most of the time effective way to resolve this kind of issue is to simply restart your computer. Thus, you have to restart your computer and see if it helps in fixing the Task Manager issue or not. If not, you can try the next given options below.
Option 2 – Run the DISM tool
If the first option didn’t work, then running the Deployment Imaging and Servicing Management tool can help you resolve the issue with the Task Manager as it will repair the Windows System Image as well as the Windows Component Store in Windows 10.
After you access the Advanced Startup options, select Command Prompt by using the arrow keys on your keyboard.
Next, type in this command: DISM /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 3 – Make sure that the display columns are selected in the Task Manager
You have to make sure that you have checked or selected the display columns you want to be displayed. So if none of them are selected, you might not see any details at all. Thus, you need to right-click on the space near Name and select the columns.
Option 4 – Run the System File Checker Scan
System File Checker or 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 that might be the reason why the Task Manager is blank or is not showing processes. 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:
Windows Resource Protection did not find any integrity violations.
Windows Resource Protection found corrupt files and successfully repaired them.
Windows Resource Protection found corrupt files but was unable to fix some of them.
Restart your computer.
Option 5 – Troubleshot the problem in a Clean Boot State
There are some instances that some conflicting programs installed in your computer might be the one that’s causing the Task Manager issue. To identify which program is causing the problem, you need to put your computer in 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.)
From there, start to isolate the problem by checking which one of the programs you installed recently is the root cause of the problem.
Option 6 – Try scanning your computer using Windows Defender
As mentioned, the Task Manager issue might be caused by some malware in the system and so to eliminate the malware, 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.
We have all experienced Windows errors over time and that can range from simple ones that will do very little to no harm and can be even system breaking making us lose our work or completely making the PC unusable. No one likes them but they happen, and usually, they happen once we least expect them.
No matter how frequent and unpleasant they might be there are ways to keep them at the minimum and even avoid them.
We will discuss steps that you can take in order to do this, simple tips and guides on how to keep your computer in top form and eliminate not just Windows, but any kind of errors altogether.
Keep your hardware clean
Believe it or not, some serious Windows errors like the dreaded blue screen of death can come from hardware issues not from the software at all. It is very important to keep your computer clean and with enough air flow so it can function properly.
Keeping applications on the drive might seem harmless but sadly that is not the case. Some applications have a certain impact on the system itself after all most of them are tweaking registry entries in Windows and sometimes having too many applications means an increased possibility of conflict over certain resources even when they are not running.
Some applications like adobe creative suite, for example, will have certain services always running in the background, and more of these kinds of applications you have, more services, more places for unexpected errors when they collide. Some of them will also install certain dependencies that could be problematic.
The general idea is: if you are not using it, uninstall it and you will be safer and more resilient to errors inside OS.
Do not use pirated or cracked software
Besides moral and law implications that using pirated or cracked software might bring you there are also certain other things that might be problematic. Certain "free" software might come packet with some problematic malware, for example, it is not uncommon for attackers to use some popular software to pack their malicious application with it.
Other things might be wrong and incomplete tweaking with application in order to bypass security and thus bringing some instability due to scripts needed to run in order to achieve this goal.
Keep your drivers updated
Errors can also come from old drivers or bad drivers, device manufacturers are not all-knowing and perfect, and sometimes drivers can wreak havoc on the system. Having updated drivers can minimize any kind of unexpected behaviors inside the operating system making it more stable and reliable.
You can check your driver version in the control panel inside the Windows OS and then compare it to the ones found on the manufacturer's site, if there are newer available it is recommended to download and install them,
Keep software updated
Applications can have bugs, and bugs can lead to certain errors both in the system and when using the app as well. It is in your best interest to get the latest patch or newer version of the software in order to avoid these unpleasant experiences.
Also, certain codecs and extensions that are installed directly in Windows can also have some unpredictable behavior, updating is the best solution to keep them in line.
Keep Windows updated
Same as with drivers and applications, Windows itself is not immune from bugs and some unpredictable issues. Luckily Microsoft is always working on fixes and features of Windows but in order to actually have benefited from that work, you will need to keep Windows updated. Sometimes a bad update can introduce some errors but you can always roll back to the previous and wait for them to fix everything and then download them all.
Check the health of your hardware regularly
Hardware components have their life cycle, more quality ones tend to last longer but eventually, they will reach the end of their lifecycle. There are a lot of testers for various components in your computer that can check different things and provide you with information about the state of your components.
If you are on Windows 11, Microsoft has included a basic health app inside OS, just type PC health check in search and start the app. For some more detailed information and advanced checks, you will have to use a custom application. There are plenty of them specialized for single components like RAM, SSD, etc. A simple google search with providing you with top results and most of them are free for personal use.
Remember, a faulty component or component that is reaching its life cycle can produce many errors inside the operating system.

We have all been there and how almost every household today has a console or PC struggles are infecting more and more people. But do not despair, we have made a nice list of potential gifts for you.
The list contains some nice essential and good things but we gave our best not to break the bank so you will not find any large screens or 300$ keyboards here. Of course, you can always get expensive gifts and if you have money for it do it, it is just we want to have affordable stuff here.
A Steam gift card
For gamers, a good game is a great gift but most of the time when we are buying a game we can miss what the person wants. That is why a Steam gift card is a great gift for gamers. He can use it and buy whatever he or she wants for its value.
Xbox Game pass
This is another for those Gamers type. Xbox game pass is a great gift even if you do not own Xbox since all games will work on PC as well. Xbox Game Pass Ultimate includes the PC version, which will unlock somewhere between 300 and 350 games automatically. It’s a subscription service, so your PC gamer will have to keep up with it. The monthly price is worth it, though.
Pack of cable ties
Almost every PC user has tons of cables lying around, and most of the time they are not really tidy. Cable ties come to the rescue!!! Let us be honest, no one likes cables that are scattered all over the place, even the computer users so if they do not have this essential piece of equipment, we are sure they will like it.
Compressed air duster
Dust is enemy no.1 for computer users, it gets into the keyboard, into small spaces, etc. It is very difficult to get it out so an air duster for compressed air is a great cleaning gift for any kind of computer enthusiast. You can get it with a can of compressed air as well so everything is ready for cleaning.
New Headset
A headset is always a great gift. Over time earbuds can deteriorate and get damaged simply just by using them and when enough time passes even cables can start losing contact and overall sound quality may drop. Usually, computer users change headsets like keyboards so if your loved one has some old headsets showing their age, a new one is a perfect present.
New SSD drive
More hard disk space is always a welcome sight for any PC user and new SSD drives fueled with new technology are faster than ones of the same size in past years making them a perfect gift.
Large mouse pad
A good mouse pad can mean a lot to a gamer. Over time mouse pad deteriorates simply with its use so a new and fancy large pad is a great gift for any user. If you want a great gift, make it with RGB light.
Roblox is a very popular online game with millions of gamers playing it each day and as such it will naturally bring a lot of malware and attack on players trying to steal and exploit them for monetary gains. The latest attack and high-profile stealing of currency and assets happened exactly in Roblox.
Malicious activities have been reported to come from chrome extensions. So far 2 extensions have been identified that have hidden malware inside them but there could be more of them currently undetected. Extensions work as a front while in the back they mine user logins and other data in order to steal stuff from the Roblox platform.
To make things worse some of the malware is within long extensions like SearchBlox. The SearchBlox extension allows you to search quickly for other users if it was legitimate but has been compromised within the last month. There is evidence that people are stealing Roblox currency with the data gathered by the hidden backdoor in it.
SearchBlox extension is still Active in Chrome Web Store, with the primary listing still with the "Featured " badge. Google is actively removing malicious software from its storefront on a regular basis but this one still lingers in it.
If you or your kid have this Chrome extension installed, uninstall it right away and always be careful about which extension you install and give access to your system, keep them updated and check various blogs and article sites to inform yourself when a bad one is found.
