Windows 8 – Change default install location of Windows 8 apps / Modern UI apps

28 Oct

In a previous blog post I compared Windows 8 tablets with other tablets. In it I said that it was nice that you could use memory cards to expand your storage, but unlike Android there is no easy way to move windows 8 / modern UI apps to the memory card and run them from there.

Since I saw the question pop up a couple of times and because I was convinced it would probably be possible, I went to look for a workaround. This is the procedure I used to change the default app install location:

  1. Close the Windows Store app.
  2. Make a new folder in the desired location. By example “D:\WindowsApps”.
  3. Run regedit as administrator
  4. Create a backup of your registry just in case.
  5. In regedit go to “HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Appx”
  6. Take ownership of this path and everything below it (inheritance).
  7. Edit the value of “PackageRoot” to your desired location. By example “D:\WindowsApps”
  8. Start the Windows Store app.
  9. Install apps.
  10. Run apps.

Beware: I’m not entirely sure if and how this affects security, so use this at your own risk.

    Hi, I was trying this out, but even when I open Regedit as an Admin, it will not let me change the permissions. Windows 8 has filled my SSD almost to capacity, and I want to install apps on one of my other hard drives.
