# How to check the operating system version?

To check the current version of Windows, use the keyboard shortcut **Windows Key + R** *(Fig. 1.18)*. In the Run dialog that appears, type the command **winver** *(Fig. 1.19)* and press **Enter**. The About Windows dialog *(Fig. 1.20)* will display the current operating system version.
