Windows 11 compatibility check for every computer in your office

Windows 10 support ended on October 14, 2025: there are no more free security updates, and for organizations Microsoft offers only the paid ESU program. For every office computer you have to decide whether to upgrade it, reconfigure it or replace it. Start with a Windows 11 compatibility check.

Windows 11 requirements

Three things get in the way most often: TPM 2.0, Secure Boot and the processor. The processor must be 64-bit and on Microsoft's list: as a rule, that means Intel Core 8th generation or newer, or AMD Ryzen 2000 or newer. Memory and storage are usually fine, although 4 GB is the bare minimum and hard to work with.

How to check a single computer

• Microsoft's PC Health Check app gives a "meets / doesn't meet the requirements" answer.
• tpm.msc shows the TPM version. The PowerShell command Get-Tpm, run as administrator, gives the same information.
• msinfo32: the "BIOS Mode" line (it must say UEFI) and "Secure Boot State".
• PowerShell Confirm-SecureBootUEFI returns True if Secure Boot is on.

That's enough for five machines. For fifty, it's a day of walking from room to room and filling in a spreadsheet.

Checking the whole office at once

If the computers already run an inventory agent, the TPM, Secure Boot, processor, memory and drive data has already been collected. In HWKeeper, open "Reports" and find "Windows 11 readiness". The report checks every PC against the requirements and shows exactly what's blocking it.

What to do with the results

• Ready machines: upgrade them in batches, starting with the ones that have a recent backup.
• Secure Boot and TPM that are turned off (on AMD processors TPM is called fTPM, on Intel it's PTT) can be enabled in the UEFI settings. If the computer boots in Legacy mode, first convert the disk to GPT with the mbr2gpt tool, after making a backup.
• An old processor can't be fixed with settings. These machines make a ready-made list for the purchasing plan.

Workarounds for installing Windows 11 on unsupported hardware exist, but Microsoft doesn't guarantee updates for such computers. For work machines, that's a poor compromise.
