VS2010 "Look at these file types" option keeps resetting to previous value

Duh, change the filter to * and Visual Studio will remember it and it will perform an unfiltered search. Not sure why I didn't think of it sooner.

This happens in Visual Studio 2017 as well, and I can't find the registry to clear. My workaround is to set the file type to *.* instead of clearing it.

I'm not sure why it's behaving randomly. My VS2010 always uses the last file filter I entered, although unfortunately it won't seem to remember me clearing out the option.

To revert it back to blank, use regedit.exe and navigate to HKEY_CURRENT_USER\Software\Microsoft\VisualStudio\10.0\Find. Edit the value named "Filter" and set the data to blank.

Next time you change it to *.sql, though, Visual Studio will store it and remember it.
