The fastest way to check your Windows installation date is by using the command line. Open Terminal or PowerShell and type the command systeminfo.This command generates a detailed report about your system. Look for the line labeled Original Install Date, which shows the exact date and time of your installation.
Below this line, you’ll also find System Boot Time, which indicates the last time your computer was started. While this isn’t the classic “uptime” feature found in Linux or macOS—which displays the number of days, hours, and minutes—you can manually calculate this data or use a more advanced command:
powershell
(get-date) - (gcim Win32OperatingSystem).LastBootUpTime
For a more streamlined approach, you can directly retrieve the installation and boot times using these commands:
powershell
systeminfo | find "System Installation Date"
systeminfo | find "System Boot Time"
Graphical Interface: Settings and Task Manager
If you prefer a visual approach, the installation date is also accessible through the graphical interface. Navigate to Settings | System | About the system to find this information.
For system uptime, open the Task Manager and go to the Performance | Processor tab. here, you’ll see how long your system has been running, though it doesn’t specify the exact start time.

This includes major updates like switching from Windows 10 to Windows 11, as well as incremental updates such as upgrading to Windows 11 24H2.
