If you are like me who like to leave my computer running on 24/7 basis whenever it’s possible, have you ever checked how long your computer has been up and running and when was the last time you turned your computer on? Let’s find it out.
Method 1 – from Task Manager
Right-click on the Taskbar, and click Start Task manager, and select Performance tab once in it.
Method 2 – from Command Line
Geeks are cool because they like command line. So let’s open the command prompt window by hitting Win+R keyboard shortcut and typing in cmd in the open box.
And type in “systeminfo†in the command prompt window.
Ooops, it only tells us when the computer was booted. That’s fine, as a geek, we can do the calculation ourselves.
You as non-geek may say this is stupid. Well, whatever, we as geek love command line anyway.
Bonus if you are a geek who also likes SysInternals toolset, you can use psinfo.exe to find out.
Method 3 – from Desktop Gadget Gallery
You can also find a few desktop gadget that displays the system uptime right on your desktop from Microsoft Live Gallery.

So let’s find it out how long your computer has been running. If you have method 4 or 5, please share them in the comment.
