How can I see the date of the Windows 10 Major Update?
Every 6 months, Microsoft releases “major” updates for Windows 10.
But the OS doesn’t install them right away. Therefore, if you do not know when the last major update was, you can check in one of the following ways.
First way:
Open “Settings -> System -> About”. The field
will be the date of the last major update.
"Installation date"
Second method:
Start the command line and run the command: systeminfo | find "Installation date"
The operation will return the date of the last major update and display.
