Windows 7 is quickly approaching "end of life". MS will soon quit supporting it, and will no longer provide updates, etc., for it or W8. The choices are either to go to W10, or another OS such as Linux. Continuing to rely on W7 will ultimately expose your system to malware, viruses and hacking...it may be months down the road...but it will happen. W10 had many problems in its first weeks/months, and left a bad taste in the mouths of early users, but those problems have largely been resolved, and now W10 is quite good.
Those of you still relying on W7 would be well advised to begin thinking of a good time to make the upgrade to W10, or moving to Linux, while you can still do so in a orderly fashion, at a time of your own choosing. Failure to do so will eventually give you an unpleasant surprise when you are least prepared to deal with it.
I've been using W10 for about 5 months, and I like it better than W7, now. One of the grandkids gave me a used Acer laptop they found at a garage sale, that was a total basket case...I have removed 36 virus and malware programs, and got it working pretty well, but it has a counterfeit version of W7. If I can't break into the administrator codes, I intend to install Linux on it.
