Manually fixing the registry

This is yet another way to fix the issue. Follow these steps:

  1. Click on the “Start Menu”, type regedit in “Search Programs and files” and hit Enter. If that doesn’t work, go to C: drive -> Windows and then double click on regedit.exe.

  2. Navigate to following location in registry: HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts\.lnk

  3. Expand this registry branch by clicking on the arrow. Delete the “UserChoice” sub-key.

  4. Close the Registry editor and restart your PC.
