---

Keyman fully supports 32-bit *and* 64-bit versions of the following
Windows operating systems:

-   Windows Server 2008

-   Windows 7

-   Windows 8

-   Windows 8.1

-   Windows 10

-   Windows 11

-   Windows Server 2012 and 2012 R2

**Note:**
Keyman works slightly differently in different versions of Windows.
Older versions of Windows have more language limitations and need extra
configuration. Windows Vista and later versions of Windows include added
security measures and some configuration actions will require you to
confirm security prompts.
