Windows 11 was fine and all but just installed ghost spectre win 10 superlite and it's awesomely smooth, fast with no guff. Best min fps I've had and has resolved some issues I had with games on standard win 10 installs. Highly recommended.
I'm not sure i'd ever trust a custom OS
This was a big deal in the XP days when the OS had so many flaws tweaking was almost mandatory (the days of under 100MB of RAM use for the OS were glorious) - but it's so easy for malware to slip in, or things to get broken.
Like when games need optional content... was it Halo that needed a second user account for dot.net or something, that broke for a lot of people?
Then stuff like Fallout 3, on a full OS has a popup *from windows* saying "hey woops you need this package cause we killed the server thing it used"
I dont mind tweak programs that let you disable/enable things with a GUI, but theres a HUGE concern about what people could have added, removed or broken to a custom OS - look at all the patchlogs for changes for examples of how you might be in the boat of non stop updates and fixes.
I can see the appeal for say, a backup OS or a gaming only OS. Security updates only, slim it right down... but not for a daily driver, and not for anything with security or reliability concerns (logins, banking, work, etc)
With 10/11 it becomes a huge problem too, as the moment you do a major OS update it's like a repair install, and bam it's all back to stock (or broken entirely)
Edit: It's a different provider but a perfect example of why i dont think many of these people are qualified to make these custom OS, or that their claims are founded in reality
(it was in my google results from looking at the other one)
