I am going to have to bite the bullet myself and upgrade to Windows 10 from Windows 7. My computer is eight years old and its time to switch.
I have been using Windows 10 for work; that's what my corporate PC runs. After getting used to MSFT moving shit around, it's honestly not that bad and seems pretty stable. Definitely boots much faster. Although that could be attributed to my corporate PC running a solid state drive versus my desktop running a hard drive.
When I upgrade, I will definitely be getting an SSD for my new system.
