When you click the Windows Explorer shortcut which is Pinned to the Taskbar, or when running explorer.exe directly in Windows 7, the following error message may be displayed with text "explorer.exe" in the title bar.

This file does not have a program associated with it for performing this action. Please install a program or, if one is already installed, create an association in the Default Programs control panel.

And using the WinKey + E key sequence causes "Unspecified error"

However, Windows Explorer may launch correctly when including additional switches such as /e or /n with explorer.exe, or double-click the (My) Computer icon. This problem occurs due to missing data in the "HKCR\Folders" registry key.

Registry Fix

To fix the problem download Folder association fix (via) unzip and run the REG file. You should be able to start Windows Explorer correctly!

    Wow. I’ve tried literally everything. I’ve searched and searched for a solution to this problem. Microsoft support was trying to make me pay $99 for a fix. THANK YOU!

    Ran sfc /scannow and it found problems but was unable to fix! I merged your registry fix into the registry. I can now access windows explorer!

    Thank you for this fix, works great.

    I bow to your greatness, Ramesh! I’ve been looking for a solution for WEEKS. Note to others (and hopefully indexed by search engines): this fix helped me solve an error with {26EE0668-A00A-44D7-9371-BEB064C98683}.
