Fix Error Code 0x80072EE7 in Windows

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.

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.

REevil is one of the most active and successful hacking groups connected to Russia and operating all over the world. The group recently demanded a huge bitcoin ransom for an attack targeting IT firm Kaseya in the USA. Since Tuesday blog and payment site run by REvil group cannot be longer reached without any kind of explanation or why. The reason behind the disappearance is unknown but has sparked speculation that the group may have been targeted deliberately by authorities. US President Joe Biden said he raised the issue with Vladimir Putin during a phone call on Friday, after discussing the subject during a summit with the Russian president in Geneva last month. Mr. Biden told reporters that he had "made it very clear to him...we expect them to act" on information and also hinted the US could take direct digital retaliation on servers used for intrusions. The timing of Tuesday's outage has sparked speculation that either the US or Russian officials may have taken action against REvil - though officials have so far declined to comment and cyber experts say sudden disappearances of groups are not necessarily uncommon. The development comes after a series of high-profile ransomware attacks which have hit major US businesses this year. The FBI accused REvil - also known as Sodinokibi - of being behind a ransomware attack on the world's largest meat processing company JBS last month.

Updating your Windows 10 computer does not always go smoothly as there are some errors you can encounter along the way. One of these Windows Update errors is the error code of 0x80246008. This kind of error can occur during different phases of an update that’s being downloaded or installed and even when an update is being initialized. If you narrow down the cause of this Windows Update error, you’ll most likely see that it is related to the deliverability of a file to a computer from the servers of Microsoft. In other words, the error might be due to conflicts from programs like Firewall as well as third party programs like Antivirus or it could also be due to corrupted disk image or system files or it could be that any of the supporting Windows Update components and services are not working properly. Whatever the cause may be, the potential fixes provided in this post can be applicable to Windows Updates as well as the Microsoft Store. Refer to the suggestions provided below to resolve the Windows Update Error 0x80246008 but before you proceed, make sure that you create a System Restore point first.

Option 1 – Apply some tweak in the Windows Registry from Command Prompt

• Tap the Win + X keys and select Command Prompt (Admin) to open Command Prompt with admin privileges.
• Next, navigate to the root location of the bootable device inside the Command Prompt command line.
• Once you’re in the root location, type the following command and tap Enter to execute it:

reg add HKLMSYSTEMCurrentControlSetControlBackupRestoreFilesNotToBackup

• After that, close the Command Prompt command line and then tap the Win + R keys to open Run utility.
• In the field, type “services.msc” and click OK or tap Enter to open the Windows Services Manager.
• From there, look for the following services:
  • Windows Update – Manual (Triggered)
  • Background Intelligent Transfer Service – Manual
• Now open their Properties and make sure that their Startup type is as mentioned above and that they are running. If they are not running, just click on the Start button.

Option 2 – Run the System File Checker Scan

If the registry tweak didn’t work, you can run a System File Checker scan instead. It is a built-in command-line utility that replaces bad and corrupted system files to good system files that might be the cause why you’re getting the error when you try updating your computer. 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.

• Restart your computer.

Option 3 – Run the Windows Update Troubleshooter

If the System File Checker wasn’t able to resolve the Windows Update error, you could also try running the Windows Update Troubleshooter as it could also help in fixing any issues related to Windows Update including this one. 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 – Try to disable your antivirus program

Disabling the antivirus program or any security software installed in your computer is always a good idea you can try when the Windows Update process does not go smoothly. So before you try updating your computer again, make sure to disable the antivirus or security program and once the Windows Update is done, don’t forget to enable the antivirus program back again.

Option 5 – Try deleting the files from the SoftwareDistribution folder and resetting the Catroot2 folder

The downloaded Windows Updates are placed in a folder called “SoftwareDistribution”. The files downloaded in this folder are automatically deleted once the installation is completed. However, if the files are not clean up or if the installation is still pending, you can delete all the files in this folder after you pause the Windows Update service. For complete instructions, refer to the steps below.

• 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.

If you got an error message saying, “Windows could not start the Windows Update service on Local Computer, Error 87. The parameter is incorrect” while you were trying to start the Windows update service on your computer, then this post could help you resolve the problem. Along with this error, you might also get any of these error codes such as 0x80240034, 0x80244019, 0x80070643, and so on. Aside from these error codes, you will also notice that the Windows Update service has been stopped. To fix this issue, here are a couple of suggestions that might help but before you go on, you need to create a System Restore point first.

Option 1 – Try checking Services Dependencies

Dependencies of a Windows Service in Windows 10 are when windows services depend on other services. Such is the case with the Windows Update service – it also depends on three different services such as the Remote Procedure Call or RPC service, DCOM Server Process Launcher, and the RPC Endpoint Mapper. Meaning to say, if two of these services are not working as expected, then the dependant service will also be affected. This could be the reason why the Windows Update service could not start.

• Tap the Win + R keys to open the Run dialog box.
• Next, type “services.msc” in the field and hit Enter to open Windows Services.
• From the list of Services, look for the following services:
  • Remote Procedure Call (RPC) Service
  • DCOM Server Process Launcher
  • RPC Endpoint Mapper
• After you find these services, double click on each one of them and check whether the Startup type for all is set to Automatic and the Service status is set to Running or not.
• If the service status is not running, then click the Start button. Afterward, check if you can now run the Windows Update service.

Option 2 – Check the Background Intelligent Service and the Cryptographic Service

• Tap the Win + R keys to open the Run dialog box.
• Next, type “services.msc” in the field and hit Enter or click OK to open Services.
• From the list of Services, look for the following services and make sure that their Startup type is as follows:
  • Background Intelligent Transfer Service – Manual
  • Cryptographic Service ­– Automatic
• After that, check if the Service status of the listed services above is set to Running. If they’re not, click on the Start button to start these services and then check if you can now enable the Windows Update service or not.

Option 3 – Reset Windows Update components

If the first two options did not work then you might want to reset the Windows Update components manually. Follow the steps below to reset them.

• Open Command Prompt with admin privileges.
• After that, type each one of the following commands and hit Enter after you key in one after the other.
  • net stop wuauserv
  • net stop cryptsvc
  • net stop bits
  • net stop msiserver

Note: The commands you entered will stop the Windows Update components such as Windows Update service, Cryptographic services, BITS, and MSI Installer.

• After disabling WU components, you need to rename both the SoftwareDistribution and Catroot2 folders. To do that, type each one of the following commands below, and don’t forget to hit Enter after you type one command after the other.
  • ren C:WindowsSoftwareDistribution SoftwareDistribution.old
  • ren C:WindowsSystem32catroot2 Catroot2.old
• Next, restart the services you’ve stopped by entering another series of commands. Don’t forget to hit Enter after you key in one command after the other.
  • net start wuauserv
  • net start cryptsvc
  • net start bits
  • net start msiserver
• Close Command Prompt and reboot your PC.

Option 4 – Run the Windows Update Troubleshooter

If resetting the Windows Update components didn’t work, you could also try running the Windows Update Troubleshooter as it could also help in fixing any issues related to Windows Update including this one. 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 5 – Try removing a value from the Windows Registry

If running the Windows Update troubleshooter didn’t help and you receive a message instead saying, “Service Registration is Missing or Corrupt”, you can try to remove a value from the Windows Registry.

• Tap the Win + R keys to open the Run dialog box.
• Then type “Regedit” in the field and hit Enter to open the Windows Registry.
• Next, navigate to this path: HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsSelfHostApplicability
• From this path, look for a value named “ThresholdOptedIn” and if you find it, delete it.
• Exit the Registry Editor and see if you can now enable the Windows Update service.

Option 3 – Run the Blue Screen Troubleshooter

Troubleshooting Blue Screen of Death errors wouldn’t be complete without the Blue Screen troubleshooter. As you know, it is a built-in tool in Windows 10 that helps users in fixing BSOD errors. It can be found on the Settings Troubleshooters page. To use it, refer to these steps:

• Tap the Win + I keys to open the Settings panel.
• Then go to Update & Security > Troubleshoot.
• From there, look for the option called “Blue Screen” on your right-hand side and then click the “Run the troubleshooter” button to run the Blue Screen Troubleshooter and then follow the next on-screen options. Note that you might have to boot your PC into Safe Mode.

Option 4 – Try running the DISM tool

You can try running the Deployment Imaging and Servicing Management or DISM tool to fix the Blue Screen error. 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.
