This computer is fast and doesn't seem to have any problems.  Microsoft told me it cannot be upgraded to Windows 11 (I think the CPU is too old), but Microsoft can shove it.  They went downhill after XP with prohibiting my best software. I do not like the wired keyboard or mouse.  They work fine, but the wires are in the way (I thought we got rid of wired devices 20 years ago?)  I am not sure what happened to my Office 2007 Enterprise (best version ever made), but it will not install, saying I have too many computers running the program.  I don't.  And I just installed one of my licensed copies on my Dell with no problems.  However, you cannot call MS for Office 2007 anymore.  I had to buy Office 2019 (a downgrade from 2007) for this computer.  It runs Office 2019 fine.
