Frequently asked questions about Windows 11 Pro
Can I upgrade from Windows 11 Home to Windows 11 Pro without reinstalling?
Yes, Microsoft supports an edition upgrade from Home to Pro directly in Windows. The change is made in the system settings under activation by entering a Windows 11 Pro product key. Installed programs, settings and personal files remain in place. A complete reinstallation is not required for this edition change.
Is Windows 11 Pro available as a 32-bit version?
No, Windows 11 is released by Microsoft as a 64-bit operating system only. A 32-bit installation, as it still existed for Windows 10, is not available. Most 32-bit applications continue to run on Windows 11 Pro, but 32-bit hardware drivers and very old 16-bit programs are not supported.
Are my files and programs kept when upgrading from Windows 10 Pro?
Yes, the in-place upgrade from Windows 10 Pro to Windows 11 Pro offers the option to keep files, apps and settings. This requires that the PC meets the Windows 11 system requirements, including TPM 2.0 and a supported processor. A backup of important data before the upgrade is still recommended, as with any operating system change.
How long does a Windows 11 Pro version receive updates?
Microsoft specifies 24 months of support for each annual feature update of Windows 11 Pro, starting from the release date of that version. Installing the next feature update restarts this period, so a regularly updated system continues to receive security updates. The currently installed version can be checked in the system settings under Windows specifications.
Do I need a Microsoft account to set up Windows 11 Pro?
Yes, Microsoft requires an internet connection and a Microsoft account during the initial setup of Windows 11 Pro for personal use. Devices that are set up for a company environment can sign in with a work account instead. After setup, additional local user accounts can be created in the system settings.
