Windows 10 free upgrade, from win7 and factory reset

[moonpig1392]

I own a windows 7 computer that i upgrade to windows 10 for free, and my computer recently started opening things really slowly.

I've tried disk cleanup, defragmenting, unistalling games/programs to free up space and have over 300gb of free space.

The bar is blue not red, yet nothing fixed it, and would like to factory reset to completely clean my computer to see if its fixed from doing all that.

I'm worried that will revert me back to windows 7 and would need to buy windows 10 to get it back.

A "Factory Reset" that came from the manufacturer will indeed try to return it to WIn 7.
That's what came from the factory.

You can do a clean install of Win 10 instead. You do not need to buy it.
