Windows uses full disk encryption with keys from the TPM by default.

Nobody says "disable disk encryption right away incase the tom forgets the keys". The vast majority of TPM's manage to not forget the keys.

They may not say "turn off bitlocker", but people definitely recommend backing up the recovery keys, and windows allows you to back up the key to microsoft because they know people won't actually back them up. Not sure if that happens by default, but they provide a variety of options for the recovery keys because there is definitely a non-zero chance you need them. There were several stories of this happening with the windows 10->11 upgrade push, where people were auto-updated and then scrambling to decrypt their hard drives.

If windows is encrypted with keys from the TPM anyways, then tailscale doesn't need to encrypt a second time.

Windows also bit me in the ass with this feature, but tailscale not enabling encryption wouldn't have helped one iota.

I'm curious. If the motherboard with the TPM dies, you're basically locked out of your data right? Keys backed up on MS server or not.
