A. Windows XP and later include the systeminfo utility. When executed, it shows a lot of information about your system, including the system's boot time. When I ran the utility, I saw:
Host Name: SAVDALWKS01 OS Name: Microsoft Windows 7 Ultimate OS Version: 6.1.7600 N/A Build 7600 OS Manufacturer: Microsoft Corporation OS Configuration: Member Workstation OS Build Type: Multiprocessor Free Registered Owner: localadmin Registered Organization: Product ID: 00426-065-0254163-86023 Original Install Date: 8/7/2009, 11:22:13 AM System Boot Time: 1/27/2010, 3:16:34 AM System Manufacturer: OEM System Model: OEM System Type: x64-based PC Processor(s): 1 Processor(s) Installed. \[01\]: Intel64 Family 6 Model 26 Stepping 5 GenuineIntel ~2106 Mhz BIOS Version: Phoenix Technologies, LTD 6.00 PG, 11/25/2009 Windows Directory: C:\Windows System Directory: C:\Windows\system32

In Windows Vista and later, you can also launch Task Manager. Up time is displayed at the bottom right of the Performance tab.
Click to expand.
There are other, longer ways to check the up time. You can check when key services, such as the workstation or server services, were started using the commands
net statistics server
net statistics workstation
and looking at the second line, which displays the date the services started (the time of the boot), as shown here.
