If you are experiencing problems accessing the Windows 8 Store using the Store tile, if you cannot update Windows 8 apps, or if Windows 8 live tiles don’t update on the Start screen, here is a collection of possible solutions.
Most people don’t have problems with the Windows Store, Windows 8 apps and live tiles, but a significant number do and it is one of the most commonly posted problems in many Windows forums.
There isn’t a single solution that fixes everyone’s fault no matter what it is and you will just have to work through the suggestions outlined here until you find the one that works for you.
Reset the Store
There is a hidden reset command in the Windows folder that clears the Store caches and it has solved some people’s problems. Go to the Start screen and enter command prompt. Right click ‘command prompt' in the results and click Run as administrator. In the command prompt window, enter wsreset.exe to reset the store. Restart Windows and try the Windows Store again
Use the Powershell
Open a command prompt window in administrator mode again and this time enter:
powershell -ExecutionPolicy Unrestricted Add-AppxPackage -DisableDevelopmentMode -Register $Env:SystemRoot\WinStore\AppxManifest.xml
start "" "ms-windows-store:"
Use the Apps Troubleshooter
Microsoft has produced a Windows Store Apps troubleshooter that can identify many problems and automatically fix them. Download the App troubleshooter and then double click the file in the Downloads folder. Tick the option to apply repairs automatically and click Next.
When it has finished, it will tell you if any problems were found and fixed.
Sync your licences
The problem could be an issue with the licences. Open the Windows Store app from the Start screen, move the mouse to the bottom right to open the charms bar and click Settings, App Updates. Click the button to sync licences. Restart Windows and try the Store again.
Check the registry
Your Windows Store problem could be a registry permissions issue and you can check this by using the registry editor. Press Windows+R and enter regedit to open the registry editor. In the left-hand pane, go to the following key: HKEY_CURRENT_USER \Software \Classes \Local Settings \Software \Microsoft \Windows \CurrentVersion \AppModel \Repository \Packages.
Right click the Packages key and select Permissions from the menu that is displayed. Select System in the list at the top and the Allow column below should all be ticked. If it isn’t, then set it to allow Full Control, Read and Special Permissions. Go to the Advanced button if necessary.
