Answer 1

Hi Welcome to Microsoft community. The error code 0x800705AA is typically related to issues with the Microsoft Store and its associated components. Here are some steps you can try to resolve the issue:

1. Run the Windows Store Apps Troubleshooter:
   • Open the Settings app, go to "System" > "Troubleshoot" > "Other troubleshooters".
   • Find the "Windows Store Apps" troubleshooter, click "Run" and follow the on-screen instructions.
2. Reset the Microsoft Store Cache:
   • Open an elevated Command Prompt (run as administrator).
   • Run the following commands:

       wsreset.exe
     

   • This will reset the Microsoft Store cache, which can help resolve various issues.
3. Register the Microsoft Store App:
   • Open an elevated PowerShell window (run as administrator).
   • Run the following command:

       Get-AppXPackage -AllUsers | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"}
     

   • This will re-register the Microsoft Store app and its associated components.
4. Repair the Microsoft Store:
   • Open the Settings app, go to "Apps" > "Apps & features".
   • Scroll down and find the "Microsoft Store" app, click on the three-dot menu and select "Advanced options".
   • Click on "Repair" and follow the on-screen instructions.
5. Perform a Clean Boot:
   • Follow the steps in the previous response to perform a clean boot.
   • Try the Microsoft Store operations again in the clean boot state.
   • Disclaimer: A “clean boot” starts Windows with a minimal set of drivers and startup programs. It helps to determine whether a background service is interfering with your game or program and to isolate the cause of a problem.    These steps of "clean boot" might look complicated at first glance. However, to avoid any trouble for you, please follow them in order and step-by step so that it will help you get back on track.
6. Check for Disk Errors:
   • Open an elevated Command Prompt (run as administrator).
   • Run the following command:

       chkdsk /f
     

   • This will scan your hard drive for errors and attempt to fix them.
   • Restart your computer and try the Microsoft Store operations again.

If the above steps do not resolve the issue, you may need to consider more advanced troubleshooting options, such as:

• Resetting the Windows Store cache: Open an elevated Command Prompt and run wsreset.exe.
• Reinstalling the Microsoft Store app: You can try to manually download and install the Microsoft Store app from the Microsoft website.
• Performing a clean reinstall of Windows 11: As a last resort, you may need to perform a clean reinstall of Windows 11 to resolve any underlying system issues.

Disclaimer: At this point, we have exhausted all troubleshooting and I recommend that we try to perform a clean install to get your computer back into a working condition. Please ensure that you backup any important data, including Documents, Pictures, Videos, and more. Let me know if you need further assistance. Best regardsDerrick Qian | Microsoft Community Support Specialist

Performed Steps 1-6, but error still persisted. Step 3 compiled with many errors concerning prerequisite files missing and such. In the end, did a pc reset and now Microsoft Store is working fine. Thank you.
