I wish I had stuck with Windows 8.1 (or even 7 before that). I finally upgraded to 10 because I got sick of the nag screens I kept getting. I regretted it almost immediately and still do.
Thanks for the word of caution. We are still holding off. Only a couple of our computers might be good candidates. The rest are probably too old.
I have built enough systems from scratch to know that it can be a real pain to install an OS. Worst of all it is a Microsoft OS and will probably be really buggy until SP1 or SP2.
If it ain’t broke, don’t fix it!!
