Back Story: I downloaded OuterWilds and the download failed to complete, being incompetent but also tech savvy, i got the "OuterWilds_Alpha_1_2_PC.zip.part" file, renamed it to "OuterWilds_Alpha_1_2_PC.zip". In an attempt to re download the program, from where it left off. however as you know, this turned the file type to a zip. So i tried to convert the file back into a "Windows shell common dll", this was the default file type association, which from my research uses the shell32.dll. Doing research online, it said, right click file >> Open with >> Select Default. Then i pressed browse as shell32.dll isn't listed, i then changed the search filter from "programs" to "all files (".")", navigated to the Shell32.dll path which i believe is somewhere in "C:\Windows\Systen32". I selected the shell32.dll file. Unknown to me, i didn't pay attention, i accidentally set this to be the default file association for all .zip files -_- I'm so stupid.
My Attempts To Fix It:
Start >> All Programs >> Default Programs >> "Associate A File Type Or Protocol With A Program". Went to .zip and changed it from "Shell32.dll" to "Windows Explorer", which i believe is the default value and then the .zip disappeard and below is the result.

-----Attempt 2 Reading online, it suggested using cmd prompt as admin to reset it to default, I can't find the webpage but i think i entered in a command similar to: "Assoc .zip=CompressedZipFolder", whatever the command, it seemed to be correct as the DOS window didn't throw any errors. When i type "Assoc" in the shell, i get a list of all file associations and .zip is there, however when i go back to the GUI listing of file associations, it is still the same as the image above. Refer to Image Reference 2 (Image Shack link Below)
Right Click .zip File >> Open With >> Select Default program. Trying to reset it as a zip using this method, the "use this as default" check box is greyed out and not checked. Refer to Image Reference 3 (Image Shack link Below). However It will open the .zip if i select Windows Explorer to open the .zip. It just wont set the default file association to be windows explorer.

Question: How do i change back the .zip file association to default, given the above constraints and with out downloading a program online to resolve the issue?
