What are the minimum hardware requirements for Windows 11?

Windows 11 comes with a different set of install requirements, and even if you were able to run Windows 10, you might not be able to run Windows 11.

To make sure that you don’t encounter any issues, we encourage you to check the official Windows 11 requirements before upgrading.

Can’t install Windows 11 even though I meet requirements?

The hardware requirements aren’t that different, and the biggest change is the need for a TPM 2.0 chip, which some older PCs don’t have. If your PC meets the requirements but you still can’t install Windows 11, that’s probably because the upgrade isn’t ready yet for your specific device.

Microsoft has lowered the requirements over time, so be sure to check the PC Health Check app constantly.

If your computer meets the Windows 11 install requirements, you’ll ensure that the upgrade process is smooth and without any issues, and you’ll avoid the dreaded This PC can’t run Windows 11 message.

Moreover, if you’re new to this, let us remind you how easy is to download Windows 11 in the first place. When available, you may simply install the update or use the Windows 11 Media Creation tool instead.
