I really wanted to mention how satisfied I am with Atlas OS. I noticed several people who are disappointed or annoyed by the absence of certain Windows functionality, but it really depends on your use case.
I am a keyboard player in a jazzrock band, and I play Vst instruments in host Cantabile on a laptop. Low latency and uninterrupted processing power is what I want. After and during installation of all music stuff, I stay offline. The last thing I need is that, during a performance, Windows decides at some random moment, to check it’s health, do a virusscan, tries to rescan all the indexes, tries to phone home, or anything else. Windows is always concerned with itself, and I had a live piano solo ruined because of it earlier.
Now that I use Atlas OS for this, I cannot believe how fast and reliable everything works. It’s uncanny how much attention and interrupts normal Windows uses for itself. Now it is just a kernel, a Windows Explorer and a startbutton, to launch what I need, and then it does just that. I did have to troubleshoot scary high temperatures during sleepmode, but I figured it out. I made it as a multiboot machine by the way, that way I can still use the laptop for safe mail and browsing on the other Win11 on the same machine.
So if you run a standalone machine for offline processing or rendering or off line gaming, you don’t need all the phone home and anti virus stuff. I would not use Atlas as a main machine with your email and finance on it.
So, this is what Atlas is to me: A very fast latency stable light defenseless Windows with nothing extra. Don’t depend on online things on the same machine.
