window store update get 0x80070002 on all programs Build 27774 canary

Hello Ttomac!

For what i read, it seems like you're running into a common issue with Windows Store updates. The error 0x80070002 usually points to a problem with the update cache. Before reinstalling Windows, try resetting the Windows Store cache by running the command wsreset in the Run dialog. You can also try checking for Windows updates or running the "Windows Update Troubleshooter" to fix any issues.

If that doesn't work, you might want to try reinstalling the problematic apps or use PowerShell to reinstall the Store itself with: 

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

Hope it helps!
