Windows slows down after install especially TiWorker win11 canary Version 10.0.25330.1000

[Donovoi]

Thank you for your work!

Just tried it on Version 10.0.25330.1000 64bit windows 11 on a 10 core cpu

Windows seems to really slow down and struggle running tasks in the background.

Especially installing anything with TiWorker seems to take forever and not finished (i was trying to install the latest sdk for dotnet version 6. After running "enable-defender", without rebooting everything seems fine.

Happy to troubleshoot/debug

Can confirm. Almost everything stoped working and takes forever to execute. @Donovoi did you find any other way to disable defender?

Can add to this, disabling Windows Defender seems to make every task excruciatingly slow/never finish/error out. Goes back to normal once Defender is back on(thanks to that, I forced real-time protection off instead of using Defender Control, since that doesn't seem to cause any slowdowns.)
Windows 11, Ryzen 5 3600x, GTX 1650, 16GB RAM.

I DO NOT recommend anyone use this until the problem is figured out. This seems new.

Thanks for bringing this up, as I haven't updated this in a while. The Trusted Installer method this project used to disable defender has been patched on Windows 11, and there are many side effects so I don't recommend anyone to use this as of right now.

I think it has to do with the new "Smart App Control" in "App & browser control". If you disable it (cannot be undone) it appears to regain the lost performance.
My hypothesis is that when running applications that Smart App Control wants to scan it waits for the antivirus, but since it's disabled, it waits for a long time before giving up.

I think my pc also slowed due to this app. I should switch to defendercontrol instead.
