How would I know if my PC is compatible with Windows 11?

How to know if my PC is compatible with Windows 11? If you prefer not to download any external file, you can manually check the key requirements using Windows' own built-in system information tools. This method is 100% native and requires no additional software.

The Manual DIY Approach is exactly what it sounds like: you roll up your sleeves and check the key requirements yourself, one by one, using built-in Windows screens and commands.

Here’s how you do it, step by casual step:

1. Check for TPM 2.0

Press Windows Key + R, type tpm,msc, and hit Enter. A window pops up. Look for "Specification Version." If it says 2.0, you're golden. If it says 1.2 or nothing at all, that’s a problem. If it says "Compatible TPM cannot be found," then your PC doesn't have it (or it's turned off in BIOS).

2. Check Secure Boot

Hit the Start button, type "System Information," and open it. In the list, find "Secure Boot State." It should say On. If it says Off or Unsupported, that’s another red flag.

3. Check your RAM

Right-click the Start button and go to System. Under "Device Specifications," look for "Installed RAM." You need 4 GB or more. Most PCs from the last 10 years have this, but it's worth a peek.

4. Check your storage

Open File Explorer, click "This PC," and look at your main drive (usually C:). It needs to be 64 GB or larger. Honestly, most drives are way bigger than that these days, but if you're running an old 32 GB tablet or something, that’ll be a problem.

This is the purest way to answer how to know if my PC is compatible with Windows 11.
