Built new gaming PC, now I can't access my game pass games or install new ones to that drive

Found this on Reddit for you to try out.

This guide is specifically for Win32 games packaged as Windows Store apps. Think games like Tomb Raider and Wolfenstein, but not special "Windows 10" versions like Superhot: Windows 10 or State of Decay 2. For those UWP games, if you can't
find them in the MSIXVC folder, please see my other guide linked below.

You will want to start by downloading the game of choice on PC 1. The game will be downloaded into
C:\Program Files\WindowsApps\MSIXVC on your OS drive, or Z:\WindowsApps\MSIXVC on any other drive. Once downloaded, you will need administrator privileges to gain access to this folder, the easiest way is to double click > Continue
> click the security tab link, then change owner to yourself, close the security window, double click again, Continue. You will have to do this for both the WindowsApps and MSIXVC folders.

Before copying anything to PC 2, start by downloading a couple megabytes of the game on the target PC, just enough so the Xbox app creates the target folder and files on PC 2. You will want to repeat the same process above of taking ownership of the WindowsApps
and MSIXVC folders.

You will notice the apps are represented as groups of three files, each starting with a long ID string. The files are <ID> with no extension, which is the main game file, <ID>.xvi (unknown), and <ID>.xvs, which contains some metadata about the game. You
can open this <ID>.xvs file in Notepad or Notepad++ to check which game ID you want to copy over (it's just a JSON file so pasting it in an online JSON formatter can make it easier to read). The game ID will be the same between PC 1 and PC 2.

Now, you're almost ready to copy. However, make sure to close the Xbox app (and kill it from Task Manager for good measure) on the target PC to ensure it doesn't have a lock on the files, otherwise you won't be able to overwrite them. Now, you should be
able to copy all 3 files with the given ID from PC 1 to PC 2 using your preferred method (direct Ethernet cable is probably fastest).

Then, simply open up the Xbox app again, and resume the download. It should immediately jump up to Downloading 100%, then install the game for you.

I was worried this would be a complex process like it is for Windows store apps (see my post here:

https://www.reddit.com/r/Windows10/comments/bywnqr/why_is_the_microsoft_store_so_anticonsumer/), but it's almost as straightforward as copying Steam games. Hopefully Microsoft adds an official way to do this as the app gets closer to a 1.0 release.

Not the answer I hoping to hear.

This may become a real problem for PC gamers using game pass as typically when we upgrade our PC we usually use our storage devices for the new builds. I don't have any issues with other PC platforms like Steam or Origin when comes to this.

I can put the drive back in my old PC and boot it, but what do I do then to change the files and prevent this from happening when I switch it back to my new PC. It seems the files are secured.

Sorry to hear it. I think the issue is that when you kept the games on the old storage device and moved it over you broke the link that the Game Pass created for them. You may have to delete the content that is stored on the old drive and start over

Hi,

This issue is due to the fact that your account is linked to the Windows 10 id of your old computer...

To solve that , you have to re-activate the same Windows 10 key id on your new computer ( click activate button , then at the error prompt, click on "i modified my pc configuration" ) , your old storage will work.

If you put a new id key Windows 10 on the new pc, the only choice is to download all your games from your purchase account.

60+ games installed on my external drive that I can't play. Can't clear enough space on the internal drive so the Xbox is essentially useless for gaming at the moment. This really needs a fix asap. Short of buying a new Xbox One with a bigger internal drive
how am I supposed to access my games collection?
