Hi. I'm David, and I'm happy to help you.
If your computer meets all the minimum requirements for Windows 11, you can upgrade to it. Sometimes Windows Update says that the computer doesn't meet the requirements for Windows 11 when it actually does. Therefore, I suggest checking if your computer meets the minimum requirements for Windows 11 using the PC Health Check app.
- Open the Start Menu, type
PC Health Check, and select it from the list of results. - Under "Introducing Windows 11", click "Check now". It will show which requirements your computer meets and which it does not.
If the PC Health Check app is not available on your computer, download and install it from the link below:

If the app indicates that your computer meets the requirements, you can upgrade to Windows 11 using the Installation Assistant (Link below).

If the app indicates that your computer does not meet the Windows 11 requirements, share a screenshot of the result so I can see if there's anything you can do to make your computer meet the requirements.
Use the shortcut Windows + Shift + S to use the screenshot tool.
Feel free to ask any questions you may have.
