Como alterar o local de instalação padrão dos aplicativos do Metro no Windows 8?
Press "WIN+R" key combination to launch RUN dialog box then type regedit and press Enter. It'll open Registry Editor.
Now go to following key:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Appx
In right-side pane, you'll see a String PackageRoot containing "C:\Program Files\WindowsApps" as its value.
You just need to change its value to your desired drive or folder. But Windows will not allow you to modify its value because you don't have required permissions. To change the value, you'll need to take ownership of "Appx" key.
- After taking ownership and assigning full control to your user account, double-click on PackageRoot and change its value to your custom location such as E:\WindowsApps or any other location.
That's it. Close Registry Editor and restart your system and now whenever you'll install a new app from Store, it'll be installed in the new location instead of default installation location.
