The Windows 10 Nazis will tell you to go back to 7.
Bunch of BS.
I've been using 10 since last July without a hitch. I think that the folks who are scared to upgrade are getting cheated.
They'll be behind the curve, IMOH.
Just my 2 cents.

There are very rational reasons not to go with Windows 10.
1) Hardware compatibility. Windows 10 is not friendly to older hardware. This has been a real problem for a lot of people.
2) Telemetry. Some people really do not care for all the telemetry data Microsoft is gathering about everything they do. All that gathering can also interfere with the performance of many applications. They have been adding it to Windows 7 and I have seen it take as much as 15% of the entire computer resources when it runs. At least, for now, you can remove that from Windows 7. You cannot remove it from Windows 10.
3) Applications. Microsoft is removing applications it does not want people to use on Windows 10. If you happen to lose an application you like, your only choice is to revert back to your original OS.
Microsoft has said, this is the last version of Windows they are going to release. From this point on, they are switching to a service based business model. That means, somewhere down the line they will start charging some type of subscription fee. When? No one knows, but it is coming.
It is all about the cloud.
