Request: Method for EFS Windows Store titles by kode54 at 9:57 PM EST on February 13, 2018
I'm looking to rip the soundtracks for both ReCore and Super Lucky's Tale, and both are stored on my Windows machine using the Encrypted File System, with a certificate apparently owned by my Windows Store account, locking access to the files to just the Trusted Installer.
Is there some hook or something which could dump the data within these apps, without resorting to files linked from YouTube videos, which may or may not be virus or trojan infected messes?
You kinda need to go on the file properties, click on security and click "add user" (depends of your windows version) and add your Username that you put in your pc. (example: MyPc_0282)
Full control does nothing if the files are encrypted by another user that you don't have the encryption certificate for.
E: I previously located the encryption certificate in my account folders, but it's encrypted with a password that I do not have. It is not my account password.

E: I don't even know what you mean by uninstall Trusted Installer. It's a Windows component that is not designed to be removed, and it handles all of the Windows Store installation and launching processes. I would just assume that removing it would prevent all Windows Store apps from even working.
I have the base certificate, which protects the individual files' AES keys, which are stored in an alternate stream alongside the actual encrypted content, but the certificate is password or passphrase or passkey protected, and I assume this key is stored in my Windows Store account somehow.
Thanks for finding that, but just as I try it, the games refuse to launch with the 803f8001 error, so I guess I have to remove and reinstall them to dodge the EFS certificate being lost or something.
E: Probably uses a machine key for the passkey to the encryption, and my rejiggering my virtual machines, including having redone the UEFI/OVMF NVRAM (OVMF_VARS.fd), probably had something to do with breaking those titles. Oh well, another 24GB to download...
