LittleBroFor the love of God, people, switch to Linux already!
Soon as I can do everything on linux I will, but until there's adequate resolution for kernal based anti-cheat applications I'm stranding with microdaft.
matari have said it over and over windows 10 in every way is better faster less ram hungry and true desktop features
Techspot's Windows 10 vs Windows 11 would disagree about it being faster.
Let3rThis happens with every update. That is why I used CTT debloater to force nuke all updates.
Yeah I use it to stall mine for 12 months.

The world of gamers is about to turn on Microsoft, causing an awakening in using every other OS than Windows 11.

No worries, since M$ investigates (read: we have no f**king clue, so we play for time) - what can possibly go wrong, once they investigatated on whom to blame;-)

Why the fck are you even rolling forward to begin with?

I'm still rocking the 24H2 LTSC and its glorious. Nothing crashes, everything works, no CoPilot shite anywhere, just W11.

Initially it's because (like 24H2) they introduce kernel and subsystem optimizations that actually improve performance - but lately im stuck rolling forward to fix the last round of bugs they introduced, and then only to introduce more bugs that need to be fixed in another update... im stuck in the cycle.

Did you know there are already 2 anti-cheat systems supported by SteamOS? Elden Ring uses Easy Anti-Cheat and works on Steam Deck. BattlEye should be the 2nd one.

If I really need to suffer from M$, I use 10- trimmed to ~ 40 background services, despite that- portable M$ Store Apps "work" - meaning,
if you unpack the .msix surprise (since reclaiming ACLs to the Administrator group or SYSTEM breaks the M$ **i*show of a cosplayed distribution,
you need to copy it off-systemdrive and purge ACLs that M$ enforces by NTFS impossible permissions (TrustedInstaller, the impossible yet owning files identity)
If you think you need M$ Store anything think twice, every single free msix/appx package from there can be installed in a way when no M$ Store is involved,
Most importantly, do not use M$ winget, it enforces 2 services, meaning - it will crap out if you use BFE, but the Firewall service is disabled (since its a joke,
that basically makes sure M$ rules are constantly reapplied and M$ can sent data home, it's not a firewall - a firewall asks users before it does something, not
if a host has been poked and then asks (if its outside its invisible defaults) if it can establish a connection, its like sending a query to a server, get a response,
meaning M$ already knows your client is online, and then asks the User - listen Pal, the server is up, so can i now upload my telemetry cause you changed the rules?
LoL, that M$ privacy 101. Again, test every claim I leave here because people assume a lot without checking it for themselves.

Second mandatory service is Appx inventory check, that winget somehow requires - even if you delete the ms-store it assumes you want by default, meaning,
winget tries to fetch packages from ms-store first (which it controls) and if its not there it will search the 2nd distriubtion channel (that is still controls, but not like the store)

Wireshark gives you a total overview what is going where- with the caveat that TLS encryption is handled by M$ reinvention - because if M$ would use opensource
libraries for that- they wont control it, so you have the SChannel s**t*show that has no way for a User to actually decrypt the traffic and see what is send where, but...
there are workarounds- and, you learn about how the tcpip stack runs- anyways, im half way through some enlightment writeup but I also have a job, anyways, whoever
understands stuff I write here about, PM me and I give you all the tools you can see it for yourselves.

Winget is M$ response to re-gain control over emerging alternatives to packaging without Redmond getting any data, scoop solves it perfectly, can be set to not use
powershell, and does not send your drive inventory to Redmond for indexing. Configuring 10 and 11 (allthough 11 is just more complex turd of a candy, 10 is easier to
bend into submission then 11 can be- since every major release - as in major builds, 22000 26000 28000 upgrades- M$ does its best to regain control and f**ck users
over - not to mention that background services needs with descritption that make 0 sense (feed it to llm and ask it about what it means, the llm craps out lol) - your system
increasingly has more data recording endpoints then the previous release, the insanity is obvious- just look how many background services are there between initial 11
release and canary, or current stable - i dont follow their confusion game of release naming, but if i recall the 28xxx build is going to be the next stable (or is?)

Follow the build overview not on M$ domains but, for example: changewindows.org/timeline/pc - and stop defending a corporation that doesn't give a s**t about
you, but wants your data

That is not really the case, gpu scheduling and variable refresh rate, has been backported to Windows 10, what feature do you need explicitly or rely on that is not in Windows 10 vs 11?

Sounds like going to the doctor with a slight sneeze, who then remedies your aching nose by using a sledgehammer on your toes, and then telling you to come back next Patch tuesday for another treatment

lexluthermiesterThat is pure daffy nonsense. Kinda proves you haven't taken a good look at Windows 11. Because, news flash, Win10 was just riddled with update glitches and nonsense. What you thought these update problems were new to 11? Dream on.. It would make much more sense if you were a Windows 7 diehard because THAT was the best version of Windows ever made.
EXACTLY, ~a year ago I've had screwed EVEN 2016 LTSB with some fresh (for that time) "security update". So, I could EZ have SAME bug for supported 2021 10 LTSC as anyone other with 11. lol

M$ could at least try to make it funny, so users can endure the next patch day, I propose beting, guess how many fixes caused new errors this week, and the winning first million get to preload the patches coming in next week, what you say? Win win for everyone!
micropage7what else you can expect? update just trying to fix the old stuff and bring another headache on the new stuff. yep i miss old win era then
it's called circular maintenance
:)

I wait for the day when someone finally discovers the mystery nagging at me since decades: what is causing the "something went wrong" error

Yeah I'm watching that emerge, I think it needs to be a majority before I'd leap though, even though I only have one game with anticheat, I'd hate to get cooked by a new one popping up on windows only.

(Update August 26, 2026):
It had already become apparent that the error was not caused by the update itself. Microsoft has now confirmed this and marked the problem as "Fixed."

"Our investigation confirms that this issue is not caused by Windows updates and is related to peripheral devices or internal device components that have RGB lighting capabilities. Such devices can install drivers or code components with filenames similar to inpoutx64. On systems where these drivers are found, the problem is then triggered by launching certain games."
It's strange that it wasn't apparently triggered by the cumulative update, even though the problems started immediately afterward, and removing it restores the previous working state.

Regards,
Fred.

Btw, the thursday/friday turd update - adds new desktop wallpaper and mouse cursor fuckup to the pool.
It's so ridicules already that any other Software Company would just disintegrate from the amount of incompetency weight it generates.
DobermannMicroslop is in top form, as always! :D
At least they managed to be consistent in one thing
