Removal of Program to reinstall not gone entirely

Question

I have 2.79 and a heap of addons that do not work when they should be, Hard Ops, etc. Also, my Alt Click on edge loops stopped working so I figured I should reinstall Blender. All the new versions say Install 2.8 but I can't seem to install it, also, I have tried to remove 2.79 to do a new clean install, I watch Windows remove the program, then I go and remove the folders, reinstall Blender, and it is the same version I tried to remove, complete with Addons, and all.

How do I completely remove everything to do a clean install since I am clearly not doing that very well, and

How do I "Install" 2.8 when I only get an exe to start the program. There doesn't seem to be any sort of "install" to place Hard Ops, Box Cutter, etc. in a directory for 2.8.

My apologies if these are repeated questions, I could not find anything related to them, and thank you for your assistance.

Answer 1

To remove blender completely go to Control Panel -> Remove a program -> remove blender, then go to C:\Users\Your-Username\AppData\Roaming\ and remove the folder called Blender Foundation (This is where blender saves it's stuff), then reinstall blender.

about Blender 2.8, here is the link to download it: https://builder.blender.org/download/

just download the .zip folder, unzip it, then run the Blender.exe file (You don't need/have to "Install" it), Thats it :)
