When you logon to your user account in Windows 8 or 10, an error message with Explorer.EXE as title along with yellow exclamation may appear, without any message text. This usually happens after removing malware from the system.

The fix for this is pretty easy – all you have to do is to remove the reference to a non-existent file from one of the startup locations in the registry. This is how to do it:

Step 1. Press WinKey + R to bring up the Run menu, type Regedit.exe and press Enter.

Step 2. Navigate to the following location in the Registry Editor:

HKEY_CURRENT_USERSoftwareMicrosoftWindows NTCurrentVersionWindows

Step 3. Double-click on the Load key and clear the existing value data to set it blank.

The above location is one of the many startup launch-points in Windows, and the viruses/malware easily add entries here. And when you clean up the virus/malware, the values may end up pointing to a malware file that is not available any more after the cleanup.
