Been using this for a few years and haven't had any issues. It makes my older CPU (Ryzen 7 3700X) perform better in games and thanks to it my 16 gigs of ram are still enough for what I do. (Playing g... See more

Atlas Os saved my Laptop
Atlas Os is just great . i alway's used stock windows 11 and after some time i used revios wich was a good boost but on 09.04.2025 i decited to get a windows 11 pro key and switch to atlas os . it's worth upgrading from stock windows to atlas os .
if you got windows 10/11 pro i recommend that u reinstall and apply atlas os
Atlas staff team is a joke
The Atlas user experience is fantastic and streamlined. However, it falls short due to the poor choice of staffing in their Discord server, a few individuals I will not name (you know who you are) that are (1) homophobic, (2) transphobic, (3) generally rude, and (4) targeting people they dislike to moderate the server in their own image and not for the good of the community, as well as being chiefly hateful and arrogant to others. This has driven multiple good people out of the server and it's a mark of poor moderation and poor human beings in general. There are multiple accounts of s*xual abuse and harassment that have not been dealt with properly, in addition to cases of tolerance for online STALKING.
Like I said, you know who you are, and you'll know who's writing this if so.

best version of windows for sure
Fast, stable, simple, not missing any features. Perfect. Been using it for about a year and a half now.
Best windows 11 optymilization 😍
TLDR: try it out its great!
props the atlasos devs to make a stable windows version!
my dumb pc would freeze up at all times so i went in and changed to atlas os and im not gonna lie everything feels a lot more snappy! (maybe its just the removal of animations but whatever) also ive realised that my pc does a lot less noise using this os and ive noticed a slight fps increase in every-game ive played recently! anyways yeah check it out if your pc is crappy and you need that freshness that comes with using an OS for the first time.

This is the first time I've seen W11 running 24/7 thanks to this. Thanks to all the contributors to this project and to the creator, BYE WIN DEFAULT. (By the way, if this message looks strange, it's because it's translated.)

It increased my Delay didnt bost any fps but lowered my cpu processes thats all it did and i lowered my processes to like 10-20
Best OS Customizatsion
I use AtlasOS for about 1,5 years. And i can tell, that that customizatsion for your os is the gratest option for mid-low range PC's. It can boost your perfomance :)

I’ve been using AtlasOS for maybe a little over a year now, I’ve noticed pretty good performance increases and definitely less ram and cpu usage. I really like AtlasOS and I think it’s the best optimization you can use at the current point in time.

I came a cross with atlas while searching a solution
For a fix for win 11 takes to much ram and cpu and people says this is the better work so i didn't hesitate and i have to say atlas is working better then win 11 self my pc is working better then before easy to install and its easy to work with

It shuts down services windows depends on
i installed atlas os yesterday and this morning I booted my PC and it said that my pin wasn't available and to setup it again. and after I clicked setup my pin it said Group Policy service(gpsvc) failed the sign in, please consult system adiminstrator.
I asked the discord community for help and they said to read again their documentation. How is that going to help? My PC is bricked and I need to read documentation?
And the problem was they disabling Windows Hello and not specifying it in the documentation. and the gpsvc issue was even dumber. why would you disable their policy service. without it enabled Microsoft thinks that I violated thei TOS. attest document yourself before disabling, again not specifying that gpsvc was disabled in the documentation.
and about the performance part is even more of an lie. they said that the processes will go from 150 to 63. guess what happend, it was from 145 to 140. but not only the CPU was not being optimised, also the ram usage. they said on their website that my ram will go from 4.4 gb on idle to 2.2. but it actually increased, it got from 4.3 to 4.6.
overall don't install it. it won't help with fps an performance in general. only if you want an destroyed windows.
