I haven't updated my windows 7 for years and have had no issues (win7 64 pro)
My advice if you are upgrading is leave your old system alone, get a new SSD(solid state drive) and put your new system onto it
Your computer will ask you at startup which one you want
If you visit lots of weird sites for bitcoins porn etc etc then you are always at risk, but if you only visit basic common sense sites then the risk is tiny
One thing you should always do is find the RESTORE option in the system properties box and set up a regular restore point, this has saved me a few times from new software issues
I always get the PRO version of any windows I get, it seems to be more stable
Still running XP Pro without any issues, it's the only one that ever got Designspark3D running
