There are multiple ways one can get the boot time or up time of a workstation or server. Some work well, others don’t.
I’ve seen a lot of people use the Up Time value in the Performance tab in Task Manager.
This value is known to be unreliable as it doesn’t take into account the time the machine was sleeping or in hibernation. Another option often used is the Uptime.exe tool which works fine but it’s something you need to have downloaded and readily available.
So what other options exist to find out the boot time or up time of a particular Windows machine?
