I don't know what current Windows 11 does, but my typical Linux Mint is single-digit seconds, and my t490 is 7 years old already. Windows 10 is a bit slower but still single second territory. With more current hardware we are talking about 2 seconds plus whatever BIOS needs, see sibling comments. Maybe you have corporate AV on the Windows PC, or funny drivers?

I'm glad it works for you, but I have witnessed several coworkers restart their macbooks (some M1, some M2, possibly M3) and I don't think I've ever seen a reboot shorter than about two minutes.

At one instance, I rolled over to a coworker who has just rebooted theirs and had a whole 5+ minute conversation.
