After the latest update to Windows 10 I ended up with no start menu (StartMenuExperienceHost was crashing, probably due to a corrupt tile database) and all the options to fix it involved using Get-AppxPackage commands to reinstall the start menu and cortana
packages. I couldn't do that because of the above error. Out of options, I took the only remaining available suggestion and did a full in-place reinstall/refresh. This fixed the start menu, but did not fix the Appx database. I still cannot run Appx Powershell
commands and nothing connected to the Store works. Attempting to install an app from the store fails, and none of my store apps are present. How can I repair this database? I am very technical and am willing to do surgery on my user profile and system appx
databases if anyone knows where those are stored.

 

Malformed PowerShell command Get-AppXPackage error

I have tried all of the suggested corrections for a start menu that is not working. The last command in the most reasonable suggestion uses as it's last two statements PowerShell and the one listed below. I have tried
this command several times, making sure there are no typing errors and every time I get the Error message below. Is there any way to repair the database disk image which is indicated as "malformed"?
