Problem: Our customer wanted to update their Windows 8 computer to Windows 8.1. That is simple enough, however when I clicked on the Windows 8 store to download the Windows 8.1 update it would open briefly then crash. I did some searches for this issue, and it seems like other people were running into the same issue. After a few Google searches, I ran across a fix for this issue. This is the fix that worked for me:
Solution: Open command prompt as an administrator.
Step Two: Enter this command prompt: powershell -ExecutionPolicy Unrestricted Add-AppxPackage -DisableDevelopmentMode -Register $Env:SystemRoot\WinStore\AppxManifest.xml
Wait a couple seconds and this command will re-register the Store. Once I ran this command the Store opened just fine and I was able to download the Windows 8.1 update.
