Far as I know the only prolems with Win 10 is the KBUpdate a couple weeks back that stopped a bunch of stuff from working, including other complex programs too, like TC. MS released an update that caused all this and there are even instructions on the site about how to remove th Update, which they recommend.
No rush to switch if you don't want to since Win 7 support will last until 2020 so there's plenty of time.
And, you also have a month to remove the upgrade if you want to. To avoid their long waits, download but theISO version (well over a Gig of data) and install that. I have one machine with the ISO update and two with the free version of Win 10 Pro. All are the same land work the same and have the same problems etc. of Win 7 and 8. The updates will automatically roll you back to your previous OS version at the touch of a couple keyclicks. Personally I think 10 is worth the effort but it still has all the typical MS BS in it that there always is from them. The first thing you'll notice is that a LOT of programs won't work and will be removed when you install 10, including Media Center, most NOrton programs and Symantec System Recovery, most scanners won't work with it, and several laser printers are uninstalled during the upgrade. So YMMV depending on what programs and applications you run. I bought a new scanner (cheap) and got a great deal on a Dell C2660dn Printer for like a third the price of equivalents at HP, Epson and other reputable printers around. I am big on Open Source apps and most of the things 10 trashed software wise I have replaced resonably witn open source programs; namely Libre Office instead of the single-source crap of Microsoft's suites of programs. The only two things I haven't replaced are WinPatrol and a replacement for MS's system controls. Multicommander and FreeCommander are all I've found for replacements and they're OK but not as intuitive to use. So don't think the love-hate relationship with MS is over: Nothing has changed that way; they still suck BUT OTOH 10 is actually, finally, much more reliable and a lot faster than 8 or 7. All in all I'm going to stick with it; it is the best OS around by far. In 3+ months I have never had a freeze-up or hang with 10, something that can't be said for 7 & 8.
