I am running Windows 7 and have adjusted something which has caused all of my shortcuts and program icons to show the same program namely Adobe Reader and when I click on any of the icon or shortcuts they only open Adobe reader, I have reinstalled Windows 7 But this has made no change, I posted this question yesterday but apparently with not enough information I hope this is better and someone can help.
It appears you managed to associate Windows shortcuts with Acrobat Reader. Here's how you can check:
Go to Control Panel, Programs and select "Associate a file type..." in the "Default programs" section. There, you scroll down to ".lnk" (in the "name" column) and see the current default is "Adobe Reader" or anything other than "Unknown Application" (that's how it should be).
If the former is the case, you're pretty screwed. There's two ways to recover from this issue:
You can try to restore the LNK handler to default state, but it's not fail-safe.
You can create a new user in the Control Panel. The issue should not persist to that user, since file associations made by one user don't affect other users. Keep in mind, though, that you'll have to transfer settings and files from your old user, so this involves some work.
Also, I don't think you performed a proper re-install (you have to boot from the Windows DVD and select "Custom install").
If you go to
There, you see a list of applications on the left, and two buttons at the bottom - "Set this program as default" and "Choose defaults for this program". The dialog windows are pretty self explanatory.
I've had a friend of mine experience the same problem. The only way that I could think of was to right click on a file thats been affected, and click on Open With, then Choose Default Programme. Select the program that should open this program and then click on the checkbox that says "Always use the selected program to open this kind of file".
Sorry that I can't think of a quicker way, but this way will at least get you back up and running using the most important files in their respective programmes.
