When we install Windows on a computer, the installation time is recorded in the system. We have multiple ways to find the installation date.
Using Systeminfo command
Run the below command from Windows command prompt.
systeminfo | findstr /C:"Install Date"
C:>systeminfo | findstr /C:"Install Date" Original Install Date: 2/16/2013, 2:57:47 PM
As you can see in the above example, it prints the exact date along with the time. This command is verified to be working both Windows 7 and Windows 8.
Using WMI command
The other way to find the install date is to use WMI commands.
wmic os get installdate
This one prints the date and time as below.
C:>wmic os get installdate InstallDate 20130216145747.000000+330
‘
How do I type the | (being “grep”, as in Linux?) in C:>systeminfo | findstr /C:”Install Date”? The ALT-GR key doesn’t show the symbol in the Terminal window (and copy-paste also does not work in a Terminal window).
The “wmic” command works fine, though.
