Quantum CogMicrosoft is blocking Windows Customization Tools
Good news hidden in the article:
Like in the case of StartAllBack, you can bypass the block by simply renaming the executable to something else. If you want to upgrade to a newer build, delete the app, update your system, and then launch it using a renamed executable.
@OP: People who are modifying Windows this deeply are not going to switch to Linux. If you're going through this much trouble, you've already tried Linux several times and left disillusioned every time. Linux does not compete with Windows as a desktop operating system and I doubt it ever will. It simply does not offer the compatibility and ease of use (including for power users) that Windows - for all its faults - has.

I did. I was a heavy Windows customizer and deeply understand it as an operating system and target for application development. I left because, at some point, I realized the OS I (one way or another) paid for was treating me like a product instead of a user, and I resent that. I don’t like the feeling of slowly losing grip on the OS as it slides into becoming adtech tooling for marketing interests instead of the thing that runs programs for me. Despite my entrenched Windows knowledge, none of my primary personal computers run it anymore, including my gaming PC. Adaptation is a lot easier than most people expect, in my opinion.
