Hello there, i am here to seek help from you all, as i failed in fixing the problem myself. My girlfriend accidently put the default set program for .lnk files to google chrome, and most of her files are shortcuts (i sent her a shortcut to an IMAGE instead of the image with an accident, so she opened it in windows photo view or w.e it's called). Now she cannot use any of the programs due to this problem. She has win7, and a dell inspiron 1564 which requires everything to be located in the D:/ drive. This lead to her transferring all files in there, and leaving shortcuts all over the C:/ drive.

After she had set it to Windows Photo viewer, i set it to be opened in Google Chrome.

Here's a screenshot of the problem,

Any ideas on what i can do to set it back to the original programs? Go to Control Panel>Folder Options>File Types, and delete the .ink extension.
Or, if Delete is grayed out, click Restore (to set it back to the defaults), then Delete.Thanks for that. But i can't seem to find "Folder options" anywhere in the control panel..

nvm, found it. But the file types aren't in it..


The above is how I do it on Windows XP. I messed up my .LNK shortcut extension just like yours and set it to open with google Chrome.
I deleted the wrong entry, and then created a new .LNK extension with the object "Shortcut."

I noticed you are using Windows 7, in which case there is no default menu for file TYPE management. There is no need to worry, though:

You can use EITHER of the third-party tools to delete and reassociate the .lnk file extension. Its LNK, not INK, as I just found out. Sorry for the above typo...
