Yeah, it's an old notebook, haha. It was preinstalled with Windows 7 and just week ago I decided to try it to Windows 8.1 and it make me waiting just to open Office.
So, what do you think? Should I go back to Windows 7 (I think I still have the windows 7 license) or jump to Windows 10?
Windows 8.1 should be less resource intensive than 7. It's mostly missing drivers and updates that might've slowed your notebook. Give it a day or two, install all updates and then fresh restart. Also check if you've multiple auto restart services/programs on startup, try disabling some non-critical ones and observe if it makes things better.
