Can my PC run Windows 11?
The quickest check is Microsoft’s PC Health Check application. But if it says no, find out why. A setting that is switched off is very different from a processor that Microsoft does not support.
Microsoft’s official minimums include a compatible 64-bit processor, 4GB of memory, 64GB of storage, UEFI firmware with Secure Boot capability and TPM 2.0. Meeting the minimum is permission to install Windows 11—not a guarantee that the experience will be pleasant.
The main compatibility checks
- Processor: it must appear on Microsoft’s supported list, not merely be fast enough on paper.
- TPM 2.0: security hardware that may be present but disabled in the firmware settings.
- Secure Boot and UEFI: modern startup protections that sometimes need configuration.
- Memory: 4GB is the official minimum, but more is usually sensible for normal multitasking.
- Storage: 64GB is the minimum; Windows also needs comfortable free space for updates and daily use.
Why can a capable PC be rejected?
Windows 11 compatibility is partly a security and support policy. An older business laptop may still feel quick yet have a processor outside Microsoft’s approved list. Conversely, a cheap compatible PC may technically pass while offering rather modest real-world performance. Checkboxes and usefulness are related, but they are not twins.
Can the problem be fixed?
Sometimes. TPM or Secure Boot may need enabling. Memory and storage may be upgradeable. The processor in most laptops is not realistically replaceable, and a motherboard change rarely makes financial sense.
Should you upgrade?
If the PC passes, first check your applications, printer, specialist equipment and backup. If it fails, consider Extended Security Updates, a suitable alternative operating system or replacement. The right answer depends on the user—not the excitement generated by a green tick.
