Windows 8.1 

It's Windows 8 but usable and actually good and gets even better with Windows 8.1 Update 1. The start button is back, there's now an all apps view on the start screen, search just searches (before it took you to a different screen, and you had to select what category you were searching in, now it's just a bar that shows up on the right side of the screen and searches everywhere by default), you can boot directly to desktop without going to start, you can use your desktop wallpaper on start, and much more plus more is still being added. You also get used to the metro interface and if you don't like it, Microsoft is adding the old start menu back in Windows 8.1 Update 2. However, it still feels like a beta and Windows 9 will probably be the next god-tier OS like Windows XP and 7, but it's a step in the right direction and feels like you're using a PC and not a tablet.

Windows 7 user: Windows 8 sucks
Windows 8 user: Yeah I want to downgrade to Windows 7
Windows 8.1 user: Why haven't either of you upgraded to 8.1 yet?
Linux user: Why are you guys still using Windows?

Windows 8.1 

Windows 8, but 100x better.
The start button is back, no booting to the start screen etc.

An OS made in Late 2013 and was made due to the reception of the original Windows 8.
Windows 8.1 was very praised. but support ended almost 10 years later on: January 10, 2023.

I bought Windows 8 a few months ago, and I hated it. but 8.1 is AMAZING!!
