Ah, the Microsoft "updates".

After the last "update" the setting for turning windows "game optimization" on and off doesn't work anymore and made factorio unplayable (it MUST be off, otherwise it optimized lag and stuttering and it automatically turns on after every larger update). Since games was the only reason I still had a pc with windows it was time to move. For funzies it tried installing some updates on the last shutdown (it got wiped afterwards).

The only pc I now have with windows on it is a early 00's pc with 98SE on it.
