Fix: Explorer.exe Error with Yellow Exclamation

To fix the Explorer.exe error at startup, remove the reference to a non-existent file from one of the startup locations in the registry. Here is how to do so.

Press WinKey + R to bring up the Run dialog.

Type regedit.exe and press Enter

In the Registry Editor window, navigate to the following registry location:
HKEY_CURRENT_USER\Software\Microsoft\Windows NT\CurrentVersion\Windows

Double-click the value named Load and clear the existing value data to set it blank.Important: If you get an error saying: Cannot edit Load: Error writing the values new contents, then re-run the Registry Editor under LocalSystem rights. Alternately, take ownership of the registry key and then clear the Load registry data. Exit the Registry Editor.

Note: The above location is one of the many startup launch-points in Windows, and some viruses/malware conveniently add entries there. The value may be pointing to a malware file that is non-existent after malware cleanup. To manage startup programs easily, use the free Autoruns utility from Microsoft.
