​OS Version

Most modern versions of the Windows OS are reasonably well optimized for performance. However, depending on your use case, updating the OS can provide improved performance.

If you are seeing a performance issue that appears to be OS-specific, see ​Known Issues to see if there is a mitigation to use a newer version of the OS.
