Solved Microsoft Office 2010

I was still happily using Office 2007 until 2 years ago.
I only moved onto to Office365 because I had a version at work that has a 5 device license.

as long as it still serves your needs - why upgrade.
"if it ain't broke - don't fix it"

stress over that decision when you have to - when no updates for 2010 are available and it has a major security flaw that directly effects you.

as of august 2020, XP market share was under 1%.

now on that front, since you are using an OS that is well past its end of life cycle and not getting security updates, personally I would be upgrading that to Win10.
but, of course, you will have to do a fresh install of Win10, then reload all your software and restore your data from backups. so a reasonably big job.
and maybe better tackled by simply buying a new PC as it sounds like this one has been around for a nice amount of time.
but the good news, Office 2010 will work on Win10.

Ah - no worries.
good to hear you're on Win10!
