How many times Windows installed?

Hi,

Either by Windows command or by other ways, how many times Windows installed in a computer?

Moreover, how do I know, when Windows installed last time?

With Regards

We can’t check how many times of a Windows installed on one computer, after clean install, all previous installation/setup information has been removed.

However, we can check the Age of Your Windows Installation.

Method 1: Open CMD or open PowerShell, depending on what you prefer. You do not have to open it with administrator rights. Type the following command and press Enter on your keyboard: systeminfo | find "Original Install Date"

Method 2: Go to Settings -> System -> About. On the right side of the Settings window, look for the Windows specifications section. There you have the installation date.

But, if your current Windows is upgraded from previous Windows, the date of above methods is a upgrade date, not original installation date, you need to navigate to the C: drive where Windows is installed. Right-click the Windows folder and choose Properties. In the Windows Properties window, look for the Created field, in the General tab. It shows when the Windows folder was created on your computer or device. This folder was created when you installed Windows.

@DSPatrick and @TeemoTang-MSFT thank you for replying for my question.

Thank you for replying for how do I know, when Windows installed last time?

Unfortunately I couldn't find the answer of how many times Windows installed in a computer?

Both answers are important for me.

There is no command to find out how many times Windows got installed on a machine. The commands and other way outs discussed here all show the installation date and time. But it won't show the original date and time if you format the drive and reinstall Windows. The date on which you reinstalled that very date will be displayed and not the earlier one.
