Explorer.exe window pop up every time at Windows 8 start up

Every time we open the computer and go to the Desktop I encounter an alert Explorer.EXE  dialogue box that shows nothing but a blank alert dialogue box with the warning icon.

There are two things we need to do to eliminate this error.

Step 1: Clear the %TEMP% folder.

• click CTRL+R and type %TEMP% and hit enter
• A window will open, clear all the items in the folder.

Step 2: Open Registry Editor and navigate to the below path.

• click CTRL+R and type "regedit" and hit enter ,it will open Registry Editor.
• HKEY_CURRENT_USER  - Software - Microsoft - Windows NT - Current Version - Windows
• Now you will find a entry with name "Load" and some path as value.Delete this value.

Now restart the computer and you will not find the dialog box  again.
