Choosing right LINUX distribution

A black screen error inside Windows 11 is a typical screen turning to solid black without any error message. This can be very annoying since it can randomly appear out of nowhere and it will appear while you are using the computer. Worry not, this is not a serious error and we have several solutions for it, so please keep reading and try them as presented in order.

Restart graphic driver

This is the first thing to check if the issue is due to software or driver malfunctioning, there is a shortcut for rebooting graphic driver inside Windows 11. Press WINDOWS + CTRL + SHIFT + B to reboot the graphic driver and see if this fixes the issue. A beep sound should be heard during this process and the screen should turn back to normal.

Check connections

Sometimes the screen can go black due to a faulty connection or cable. If you have it at your hand try a different cable or slightly and gently nudge the existing one to see will screen flicker. If you are on a laptop try gently moving the lid from back to front and pay attention to the screen. If screen flickers or picture returns with this method, cable or connector needs to be replaced.

Clean your computer

The black screen can be because the computer is overheating. If this is the case either fan inside is not working properly or there is a lot of dirt and dust that needs to be removed so airflow can be established again for proper cooling. We have an article on errortools.com on how to properly clean your PC but if you are not technical enough maybe the best solution would be to call someone who is or to take the PC to service for cleaning.

Change The Projection Settings

Press WINDOWS + P to open projection settings, check to see if PC is set to PC screen only. If any other option is selected change it to PC screen only since this can cause random black screen issues.

Uninstall latest updates

If this problem has started to manifest itself during the latest update, go to setting and roll back from the latest update to fix this issue.

Scan system for malware

The black screen can also be caused by various viruses and malware. IF you have anti-virus software, run a full system scan to check it for malware. If you do not have one, download a free one and run a system scan, we recommend Bitdefender.

5 Windows 10 Upgrade Errors

The recently released Windows 10 captivated the mass but its rollout, polished as it might have been, proved everything but seamless. Surf the Internet and you’ll get the gist. People are complaining and they need assistance. Assistance with what you might ask? Many have attempted to make an upgrade but failed after encountering various strange combinations of letters and numbers. These are none other than error codes. If you’ve tried and failed, feast your visuals below as you might encounter one of these 5 Windows 10 Upgrade errors.

Error Code 0x80073712

Encountering error code 0x80073712 in no way implies that you need to throw out your computer system and acquire a new one. Not at all! This error code simply means that a very important file to Windows might have gone missing or corrupted. This file is crucial to Windows update so without obtaining this file, you won’t be able to proceed with the update.

Error Code 0x800F0923

Likely, there are many programs and drivers installed on your computer. They all play a vital role. However, if you’ve received error code 0x800F0923, it might be time to consider or turn your eyes to installed drivers on your system. Why? Error code 0x800F0923 means that there’s a driver or driver on your current Operating System that’s not compatible with Windows 10. There’s clearly a dilemma here.

“We couldn't complete the updates. Undoing changes. Don't turn off your computer.” Or “Failure configuring Windows Updates. Reverting changes”

That’s a pretty odd error but I will say it's slick… That Windows 10 upgrade error is straightforward. Microsoft is just letting you know that they won’t be able to complete the update to Windows 10 and so they are putting your computer back to where it was. How nice of them.

The error messages above are pretty generic and will manifest when the upgrade fails for one reason or the other. To resolve this issue, you’ll most definitely have to decipher what error code was presented. Identifying that will provide a glimpse into exactly what steps you need to take.

The Update Isn't Applicable to Your Computer

I don’t know about you but I strongly believe Microsoft is subtly letting you know that your computer system is old and needs to be thrown out. Also, this update could imply that your PC needs to install important updates to rev you up to the requirements. All relevant updates to your computer must be installed before you can get past this stage.

Error… “Something Happened”

This Windows 10 upgrade error has been the talk of the Internet. In fact, users of Windows OS have been making it a mockery. Clearly, not many have had success after encountering this error. Obviously, “something happened” but it’s just not easy to decipher what went wrong. Microsoft is still trying to figure it out.

Solution

If you are checking for an update on your Windows 10 PC and you got the error 0x80070005 due to some ACCESS DENIED permissions issue, then read on as this post will show you what you can do to fix the problem. For some reason, the Windows Update does not have enough rights or permissions to continue further which is why you’re getting an error instead. Thus, the first thing you can do before you troubleshoot further is to make sure that you’re logged in as admin. However, if you’re already logged in as one, then here are some suggestions that might help you fix the Windows Update Install Error 0x80070005.

Option 1 – Restart your computer and try installing the Updates again

You can restart your computer and then try installing the updates once again. There are instances when a simple restart resolves Windows Update errors. Thus, after you restart your computer, check for updates once again and see if you’re still getting the error or not.

Option 2 – Delete the contents in the Software Distribution folder and Catroot2 folder

• 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.

Option 3 – Try running the Windows Update Troubleshooter

Running the built-in Windows Update troubleshooter is one of the things you can first check out as it is known to automatically resolve any Windows Update errors like error 0x80070005. To run it, go to Settings and then select Troubleshoot from the options. From there, click on Windows Update and then click the “Run the troubleshooter” button. After that, follow the next on-screen instructions and you should be good to go.

Option 4 – Take control of the User App Data

There are times when permission to access the files is not configured correctly. As a result, it blocks the downloading of the updates. Thus, you have to take full control of the User App Data which is placed at C:/Users/USERNAME/AppData.

• First, go to C:/Users/USERNAME/AppData and right-click on it then select Properties.
• Next, click on the Edit button in the Properties window and click OK to confirm if you got a User Account Control elevation request.
• After that, select user/group from the permission windows or click on the Add button to add another user or group. It would be best if you add “Everyone” to give permission.
• Then check “Full Control” under the “Allow” column to assign full access rights control permissions.
• Now edit the permission to Full Control for “Everyone”.
• Click OK to save the changes made and then exit.

Option 5 – Try to update Windows after a couple of minutes or an hour

There are times when the issue is from Microsoft’s end. It could be that there’s some issue with Microsoft’s server so it would be better if you give it a couple of minutes or an hour or so before trying to run Windows Update again.

It has been reported that there are systems out there with Windows 11 operating systems that do not use the whole RAM memory installed in the system. If by any chance you are one of the unfortunate users that has encountered this issue, fear not, we have a solution for you.

Enable memory remapping inside BIOS

In order to do this fix, you will need to enter BIOS on your system. How entering BIOS is different from system to system depending on your manufacturer, especially if it is a laptop this step you will have to do alone. Go to your motherboard manufacturer or laptop manufacturer and see how to enter BIOS.

1. Enter BIOS (80% of the time this can be done by pressing DEL or F12 while the system is turned ON)
2. Locate System Agent Configuration option
3. Select Memory Remap Feature and Enable it

Your BIOS might be different from ours and you might not have the System Agent Configuration option, in this case, go through the setting and try to locate Memory Remap Feature. If this feature is missing as well move to the next step.

Rearrange RAM modules on the motherboard

Sometimes RAM memory cannot be slotted properly or just purely switching them in slots can solve the issue. Take RAM out, clean memory slots, clean motherboard connectors for them, and place them back in a different order. If by any chance none of the methods worked, then the issue might be in the hardware itself, either memory banks themselves, motherboard, power supply, etc. If this is sadly the case, you will have to locate the issue and replace the faulty part. If you are not technical enough for this adventure, the best solution is to take a PC to a computer repair shop.

Corsair is well known for RAM memory modules for PC but then it has expanded to PC peripherals and even selling some pre-build computers as well in past few years. New Corsair expansion now includes a laptop line, starting with their new gaming laptop Voyager.

Voyager laptop is packed with a mechanical keyboard and MacBook-like touch bar for your typing and pointing needs. It is built with a 16-inch QHD+ screen packing 240Hz that is run by Radeon 6800M GPU. Also inside lurks AMD 16 thread Ryzen 9 6900HS CPU, Wi-Fi 6E support, Dolby Atmos audio, and full HD 1080p WEB camera.

The keyboard has low-profile mechanical Cherry MX switches with per-key RGB lightning and above is what Corsair calls a macro bar, with 10 shortcut buttons and a small LCD in the center.

Corsair is also including a few features that tie in with its other products. Many of the company’s keyboards, mice, and other accessories use the ‘Slipstream’ USB wireless adapter, which is built into the Voyager laptop. The macro bar is also configured using the same software used for the Elgato Stream Deck, a popular product sold by Corsair.

Bluetooth troubleshooting, I believe firmly that each one of us who has Bluetooth sooner or later had some issues with it, after all, it seems that it is in nature of radio transmitters to from time to time due to nature of signal and nature of Windows loose communication between them and can cause device which seems to work properly but can not establish the connection. Most of the time Bluetooth issues are like that, the signal gets lost, the connection is broken, and establishing it again can be sometimes real pain, luckily for you, we have experience in this field and are here to help you and provide you with tips how to solve Bluetooth connection issues based on our own struggles.

1. Check if BlueTooth is ON

   Yes, this seems stupid and sounds a lot like is it plugged in but here me out. Due to lost connections and different power plans setting inside your Windows, your Bluetooth receiver might be actually turned OFF thus preventing your other device to find your computer. Checking to see if Bluetooth has been by some accident turned OFF and switching it back ON should be the first thing to do and this could be a simple solution for your problem.

2. Restart the BlueTooth device.

   Yup, another of these have you tried turning it OFF and turn it back ON advice which seems like tech cliche but in the case of Bluetooth, this can actually solve your problem. Radio signals and radio connections are not the same kinds of beasts like cable ones and sometimes Bluetooth device remembers certain information and can cause conflict. Turning it OFF and then back ON will clear its memory and cache and you will be ready for a new start hopefully solving your issue along the way.

3. Check power supply

   If your Bluetooth device does not have a battery indicator, it would be wise to check on the battery status of the device. Sometimes we forget to charge batteries, sometimes someones have drained them. Checking the battery or just checking if the power supply is working properly should not be overlooked and it definitely should be on your to-do list of quick solutions.

4. Restart PC

   Sometimes most simple solutions work and if restarting your Bluetooth device did not work, maybe restarting your PC will. When you restart the PC, you clear the cache and many other things that could potentially be the reason for connection issues.

5. Checks BlueTooth device distance from computer or interference from obstacles

   The Bluetooth device operates via radio waves, and like wi-fi, if the distance from the computer is too large or you have some thick walls in between signal will degrade and be almost useless. Be aware that your PC might catch device waves and detect them but the signal itself could be too weak for the connection to work properly. Take the device and move it closer to the PC to see if the problem will go away, if it does issue was in distance or walls.

6. Reinstall or update device drivers.

   Sometimes the issue could be in Windows update and old drivers, make sure that all of your drivers are updated with the latest version and that Windows itself has the most recent update in it. Trying to reinstall device cold also solve some the issue.

7. Remove and Pair deice again

   if you tried all previous steps, try removing the device from Windows and then pairing it again. This could solve the issue since Windows itself could have mistakenly saved it like something else and can not recognize it.

8. Use Windows troubleshooter

   If everything else failed, right-click and go to troubleshoot. Windows troubleshooter will try to find the issue and direct you to a solution.

If sadly none of these things do work, you should contact the device manufacturer since it is a very good chance that the problem is one of a hardware nature.

Hello and welcome everyone. In today's article, you will learn how to lock folder and content in it. Please be aware of few things:

1. The method is shown here works, but you need to be careful and follow step by step or you will damage your files permanently,
2. If you forget your password, you can not access your files anymore
3. Your files altho protected can still show up in recent files of some applications

All of that being said, let us start with locking the local folder on the computer with the password. Go to the folder where you have files that you would like to hide and lock with a password. Enter the folder and create the new text file inside it. Skip the name for now and go inside it. Copy and paste the following code inside the file:

---

cls @ECHO OFF title Folder Locker if EXIST "Control Panel.{21EC2020-3AEA-1069-A2DD-08002B30309D}" goto UNLOCK if NOT EXIST Locker goto MDLOCKER :CONFIRM echo Are you sure u want to Lock the folder(Y/N) set/p "cho=>" if %cho%==Y goto LOCK if %cho%==y goto LOCK if %cho%==n goto END if %cho%==N goto END echo Invalid choice. goto CONFIRM :LOCK ren Locker "Control Panel.{21EC2020-3AEA-1069-A2DD-08002B30309D}" attrib +h +s "Control Panel.{21EC2020-3AEA-1069-A2DD-08002B30309D}" echo Folder locked goto End :UNLOCK echo Enter password to Unlock folder set/p "pass=>" if NOT %pass%==Your-Password-Here goto FAIL attrib -h -s "Control Panel.{21EC2020-3AEA-1069-A2DD-08002B30309D}" ren "Control Panel.{21EC2020-3AEA-1069-A2DD-08002B30309D}" Locker echo Folder Unlocked successfully goto End :FAIL echo Invalid password goto end :MDLOCKER md Locker echo Locker created successfully goto End :End

---

Now locate this line of code in the document: if NOT %pass%==Your-Password-Here goto FAIL and replace Your-Password-Here with your password. !!! Write down somewhere your password, if you lose it you will lock the folder even for you !!! Save the file as FolderLocker.bat and double-click on it to execute it. If everything was done correctly, a new folder with the name: Locker Move files that you want to hide and protect inside that folder. Double click again on FolderLocker.bat The command prompt will appear with the question do you want to lock the folder, press Y, and press ENTER. The command prompt will close and the Locker folder will disappear. In order to unhide and access the folder, you will need to double click on FolderLocker.bat again but this time command prompt with ENTER your password will appear. Type in your chosen password and the folder is back. If you wish to hide and lock it again just double click on FolderLocker.bat again, confirm with Y and it is hidden again.
