Window 8 File Association Window
While I was tinkering with my Ragnarok Online installation folder (It sounds kind of childish but yes, I am addicted to this game and their cute sprites.) to make it run with Windows 8, I accidentally associated a file (.lub) with notepad. Since I hate programs associating themselves to files that they don’t really open, I tried to unassociate it. In Windows 7, life was easy. You just have to use a program called “Unassociate” created by a Microsoft MVP. However, even though Microsoft stated that Windows 8 will have backwards compatibility with Windows 7 programs, this tiny utility won’t work on Windows 8 so in turn I pumped up my Nightly (by Firefox) browser and searched the internet for answers. Fortunately, someone over the planet has the same problem as I do. So here is what other people suggested in removing file associations in Windows 8:
Quoted from E-Jagg of Microsoft TechNet
If you don’t know how to get to the command prompt, follow this:
Type the keys: [Win] + “R”, which brings up the Run window.
Type the keys: “cmd”, then type [enter]
You should be looking at that little black box now. Now if you need some help type in these words:
C:> help assoc
My particular problem was this: I was looking at C:\windows\prefetch, and all of the files were *.pf, and I accidentally associated all of my prefetch files with a program.
To undo the association:
assoc .pf = “”
now my *.pf files will associate with NO file
To test what your computer uses to open *doc files type, at the prompt:
C:> assoc .doc
The display states: Word.Document.8 opens your doc files.
So that is what he did. I used it but unfortunately It did not work yet. Maybe my machine needs restarting. I haven’t restarted this one since 2 weeks ago and I am not planning to restart it yet. If some good soul out there tried this method and it worked, kindly comment and I will credit you in this post. Thanks!
