Last week I had a business computer with XP and Microsoft money (which is no longer supported) and the hard drive was going bad. I cloned the hard drive because I had lots of business related contacts and was hoping to limp along until I could find a way to transfer the data.
Of course I got a pop up from Microsoft noticing the change in the computer and it locked up all Microsft software so no changes could be made until I installed the original disc. Remarkably I had the disc from 9 years ago but it still didn't recognize it.
Microsoft was of no help, Word, Access and excell wouldn't work even though I have the original, paid for installation discs.
Out of desperation I purchased a new computer with Windows 10. (There is no free upgrade for XP or Vista) Of course, I lost all information and functionality of Microsoft Money. Additionally my Microsoft Office 2010 wouldn't install and I had to purchase the 2016 version, which is now a yearly screwing, er I mean fee.
I also had to purchase a new accounting software, Quickbooks Pro 2016 and it won't load onto Windows 10 but did install on a desktop publishing work station with Windows 7 professional.
The new Windows 10 Interface is not very intuitive and there is no way to switch to a more conventional look like in previous editions.
I wouldn't switch if you didn't absolutely need to and will not be updating my desktop publishing or video editing computers any time soon. Compatibility with older Microsoft products is terrible (I'm sure it on purpose) but I was able to make it work with a HP all in one printer that is a year old.
Good luck! (Don't do it!)
