File Types Tab in Advanced Options under Indexing Options is not usable.
When I go to Control Panel / Indexing Options / Advanced and click on File Types the application hangs for about 10 seconds and then Indexing Options and the Advanced screens both close - no warnings or errors. I have tried rebuilding the index and I also
tried removing all locations with the modify option. Any suggestions?
If the issue does not recur then, I would recommend you to perform clean boot.
Putting your system in clean boot state helps in identifying if any third party applications or startup items are causing the issue. If yes, you may have to contact the program manufacturer for any updates or uninstall and re-install the program.
Refer the following Microsoft KB article for more information on how to troubleshoot a problem by performing a clean boot in Windows Vista or in Windows 7:
Note: After troubleshooting, make sure to put the computer to start as usual as mentioned in Step 7 in the above KB article.
If the issue recur in safe mode then, try sfc scan.
SFC /scannow is a super-useful command you can use in any Windows version. When the SFC (System File Checker) command is used with the /scannow switch, the tool will scan all of the important Windows files on your computer and replace them as necessary.
Missing and corrupt operating system files (like many DLL files) are arguably the biggest cause of major Windows issues. Considering that, plus the fact that SFC /scannnow is completely automatic and very easy to use, the tool should usually be one of
your first troubleshooting steps.
