Microsoft forced win11 on customers… we had 100+ pc’s upgrade on their own… gave f all about group policies.

Happy to not be a part of endpoint management team and to not care if my work pc is on wi10, win11 or anything else… I need a browser, an ide and a terminal to do my work

Bad IT.

I remain thankful that Win11 is fussy about what it will install on. It needs at least:

• UEFI boot mode & GPT partitioning of the disk
• TPM 2
• Secure Boot capability

Nixing any one of these will prevent an automatic upgrade, regardless of what group policy etc is in place. On a bunch of new Win10 builds from a while ago, I set them up as CSM/MBR and turned off the TPM in BIOS. Absolutely no chance of surprises there, even if I accidentally mark a machine for upgrade.

My network is small though, < 50 clients. When the bullet must be bit, I have the time to add the client to the ‘will upgrade’ AD group & go over things with the user(s). Then run through converting MBR to GPT, switching to UEFI and enabling the TPM again.

After that it takes care of itself and pulls down a load of QoL fixes post-upgrade.

I don’t think you’re the first nor will you be the last to be smacked with a driveby install that fucks up your equipment, sadly :(
