NEVER switch to Windows 10. If you find that Windows 7 is no longer doing it for you its time to learn how to use Linux (or start taking your chances with pirated/cracked versions of Windows).

The problem with Win10 is that you no longer own your copy of the OS, you're simply "renting" it. So you're not allowed to opt out of "updates" that break things and at some point Microsoft will find a way to force you to re-buy their OS or start making monthly rent payments to keep your computer running and not lose all your data.

Went through this crap with Adobe in the last couple years (Creative Suite is gone and now its Creative Cloud ... which you have to pay a monthly fee to keep using and its constant "updates" are always breaking the expensive third party plug-ins I rely on to do my job so we keep having to re-buy those every so often too).

This cloud crap ("software as a service" ie rent not own) is the future of computing. I really recommend everyone start exploring open source operating systems like one of the myriad flavors of Linux because there will come a day when Apple, Microsoft and Google will screw each and every one of us real hard.

The days of "install it and use it as long as you like" are rapidly coming to an end.
