Over time, particularly if you have a low specification setup, your Windows installation may degrade, become sluggish or even unusable, although hopefully you will make the decision to reinstall before it gets that bad.

It may be interesting or even useful to be able to see when the operating system was installed. If you are a constantly heavy user/surfer, it could give you a rough idea how long it may be before you have to reinstall again.

For the purpose of this article, I’m using Windows 7 but it will work on other, earlier operating systems.

Click Start and type cmd

Right click cmd in the programs list (it will be at the top) and select Run as Administrator

In the command prompt window, at the flashing cursor, type systeminfo | find /i “install date” You can copy and paste the command from here but Control + v won’t work in the cmd window, you have to right click in the window and paste.
