Windows 7, unfortunately, sooner or later you will have to let go into the world of retro and antiques. Maybe your hardware currently has drivers for Windows 7, but at any time, break the motherboard / video card, or you buy a additional sound card, a new webcam, or any other device that does not have drivers for Windows 7 - and Immediately you will begin to experience big problems.
Fortunately, there is a good alternative to Windows 10, which is so disliked due to spying and due to enforcing automatic updates that cannot be disabled.
Your salvation it is Windows 10 LTSB(long term servicing branch).
I wont long describe here why it is really good - in internet about this there is lot information. This is a real salvation.
And in order for new and fast Windows 10 LTSB to look like old lovely Windows 7, you just need to use Classic Shell.
