QUESTION:
DLL files "open with" XXXXX problems
1.I used the open with dialog a while back and forgot to "uncheck" the box that says " always use this program to open" and now all my DLL files show open with notepad.
2. By accident, I opened a .dll file with notepad, and ever since, whenever I try to open something that needs a .dll, it doesn't work... Please help me as soon as possible.

3.I noticed that all my dll files have changed. They all open with Windows Media Player, which I know is wrong. What file type are they supposed to be? And how can I change it?

How do re-associate dll files appropriately?

ANSWER(wrong):
If you get the answer where people says:

1."You don't have to do anything. Notepad is the right program to open dll files."

2."To change association with Windows Media Player open Windows Explorer, go to Tools->Folder Options->File Types (on Vista it's under Control Panel->Default programs-> Associate a file type or protocol...),scroll down to .dll entry and you can change it from being Media Player type of file to, say, Notepad file (which still makes no sense, but that's the most Microsoft allows to do about it without hacking the registry)."
  
3.This wont make any difference in their working just ignore it!!

And you should NEVER 100% believe that:
"Dll errors are usually caused by a corrupted Windows registry due to invalid entries that exist because of software you are no longer using, or an improper software installation or removal. Failure to fix a corrupted registry can result with severe PC problems."

NEVER spend money buying some sort of registry repair tool before you try every possible ways to fix the problem.
