Microsoft will end support for Windows 10 October 2025. So if you have an older computer, you still have time with it.
And if you do have an older computer, the answer to continuing support is NOT to upgrade to Windows 11 as Microsoft will not support that upgrade. While your machine may take the update, it doesn’t support it so at that means is that it may work, and it may not. It may work on Monday and not on Friday. And when it doesn’t work, there will be nothing to be done except maybe a rollback. So do not update your older computer to Windows 11.

The issue with older computers is a security one. In order to run Windows 11, computers need an EUFI and a TPM. The TPM is a cryptographic module that enhances computer security and privacy. Protecting data through encryption and decryption, protecting authentication credentials, and proving which software is running on a system are basic functionalities associated with computer security.

Older computers don’t have it and it can’t be added after production. EUFI is basically the software to run the hardware.
If you want to keep your older computer running, install a solid state drive and keep it at windows 10.
Windows 10 machines running mechanical hard drives (older drives) are showing high disk usage (type task manager in your white box and see if you look like the above picture when your computer is running slow). If you are experiencing this problem, upgrading the hard drive is the solution. This upgrade is about $250.00 per machine.

Older Computer owners take note
