You probably know that Windows Taskmanager as of Windows 7 shows the uptime on the Performance tab as can be seen in the next image:

TaskManager on Windows Server 2012R2 showing the uptime in a red box.

You can even start a graphical version of taskmanager on a Core Server by typing taskmgr on the command prompt.
You can also use the command prompt on all Windows operating systems to get the last power on or reboot time with the command:

net statistics server

It will show you the following information:

Server Statistics for \\NLAALDC2

Communication devices accessed     0
Print jobs spooled                 0

Times buffers exhausted

  Big buffers                      0
  Request buffers                  0

The command completed successfully.

We are interested in the line that states: Statistics since 11-5-2014 18:37:02 as this denotes the last reboot or power on.
If you only want this information, you can easily filter for this using:

net statistics server | findstr /c:"Statistics since"

On a desktop or notebook you can use:

net statistics workstation

Since version 6 of Powershell there is a command to get the uptime Get-Uptime.
