MQ, As posted above, in late June I moved to a Windows 10 desktop (still have a 7 laptop). Some years ago I bought a tablet that came with Windows 8, and that truly terrible OS scared me off of replacing my other W-7 computers or upgrading their OS.
W-10 has a definite learning curve, so you're wise to get some assistance navigating it. All in all, it's not nearly as big a leap from 7 to 10 as it was from 7 to 8. (I only use the 8 tablet for reading electronic books because I so despise the OS.)
Wishing you the best with your new computer! Please let us know your impressions.
