Can my PC run Windows 11?
It needs TPM 2.0, Secure Boot, a supported processor, 4 GB RAM and 64 GB storage. Here's how to check and what usually blocks it.
If it has TPM 2.0, Secure Boot capability, a supported processor, at least 4 GB of RAM and 64 GB of storage, yes. The quickest way to check is Microsoft’s PC Health Check app, which tells you whether the PC qualifies and which requirement it misses.
The common blockers
TPM 2.0
Many PCs from recent years have a TPM chip or firmware TPM that is simply turned off. It can often be enabled in the UEFI settings, where it may be labelled TPM, PTT or fTPM.
Secure Boot
This needs UEFI firmware rather than old legacy BIOS mode. Switching modes can require converting the disk layout, so back up first.
Processor
Windows 11 supports a defined list of processors. Older chips usually aren’t on it, even if they still feel quick. This is the blocker you can’t fix with a setting.
What if it doesn’t qualify?
Workarounds exist to install Windows 11 on unsupported hardware, but such PCs aren’t supported and may not be entitled to updates. For anything you rely on, replacing it is the safer route.
