When did my Windows 10 last boot up?
Sometimes curious about this, usually because I forgot to note what time I arrived at the office, and I keep forgetting how to check. So, here's some commands I found on SuperUser which seem to do the trick:
> systeminfo | find /i "Boot Time" System Boot Time: 15.10.2021, 08:37:29
> wmic os get lastbootuptime LastBootUpTime 20211015083729.500000+120
> net statistics workstation | find /i "Statistics since" Statistics since 15.10.2021 08:37:45
Also discovered this one, which will create a more thorough report, which can be interesting to look at:
> powercfg /sleepstudy /output report.html && start report.html
