WINDOWS 11 the current version of Windows.   As of October 2025 Microsoft dropped all support for Windows 10.  There will be no security patches any longer so computers running 10 will be pretty unsafe on the internet. It is not that your computer will quit working – just that it will be unprotected.

​​

Some applications that ran fine under Windows 10 will no longer run until the computer is updated.  One example of this is Quickbooks.  You must be running Windows 11 to use its current version.

Windows 11 and older computers

​

If you have an older computer there is a good chance Windows 11 CANNOT be installed on it. Microsoft has decided that the computer must be at least an 8th generation processor, have a specific piece of hardware (TPM) and a couple of other things that older machines do not have.

Bottom line - they basically don't want people to use their old stuff and want to force you to buy new equipment. It is not us – it is them.
