Windows installation failed after trying many different ways to Install & Download error - 0x80070002

Anonymous

I started getting Download error - 0x80070002 every time i would try to update windows. And then the MS store stopped working. And whenever i try to open a media file i get the message package couldn't be registered. I tried every single suggestion on the various MS tech support pages.

I also tried resetting and also reinstalling windows - both from the power shell, from a downloaded disk image, and from online. And every single time i tried, it says Operation Failed. Or Windows was not able to be installed. I have tried literally everything and don't know what to do. Are there any suggestions please?

Thanks, please do the following:

Download cbsfix2.reg and save it to a folder on the C drive -- e.g., C:\Fixes
Download AdvancedRun from Nirsoft and run it.
Using AdvancedRun, launch c:\windows\regedit.exe as TrustedInstaller (see Screenshot)
In the Regedit window, click File, and click Import...
Dismiss the "Location is not available" message box by clicking OK.
In the "Import Registry File" window, in the "File name" text box, type C:\Fixes\cbsfix2.reg and press Enter.
After the import is successful, exit Regedit.
Restart Windows.

Try to install updates.

Please use the full path to the executable:

"C:\Program Files\Acelogix\RegBak\regbak.exe" /dir:"C:\RegBack\ " /reg:su /limitcount:7 /overwrite:y /compress:y
