To find out which version of Windows is on your computer or laptop, follow these steps:

• Click the Start button > Institutions (the gear icon).
• In Windows 10, click System. In Windows 11, this item is already open by default.
• Click at the bottom Info.

Behind ‘Version’ (under ‘Windows specifications’) is the version number of Windows.

Windows installs updates automatically. This keeps the computer working optimally. Occasionally leave the computer on for a few hours so that necessary updates can be processed. If necessary, read the tip ‘Check Windows Update settings’.
