Hello Pio, Do you like to know the version of OS?. If so, here is a command which helps you to identify os version. wmic os get Caption,CSDVersion /value Regards, Ravikumar P

Or you can click on start, right-click Computer and then click on Properties.

Yet another way... Start -> Run -> type Winver {Click OK or press Enter} Regards, Santosh I do not represent the organisation I work for, all the opinions expressed here are my own.

Another way is to look at the lock screen, should tell you the OS.
