Wat voor windows heb je, Windows ME??
Als je Windows ME hebt doe je het volgende: (ik hoop dat je wat engels kan

)
Desktop Is White and Error Message Reports a Windows Explorer Error in Browseui.dll
When you start a computer that is running Microsoft Windows Millennium Edition (Me), the desktop may appear white and the following error message may appear:
Explorer has caused an error in Browseui.dll
RESOLUTION
To resolve the issue, run the Registry Scan utility:
Restart your computer using the Windows Me emergency startup disk.
Use the arrow key on your keyboard to select Start Computer Without CD-ROM Support, and then press ENTER.
At the prompt type scanreg /fix, and then press ENTER.
After the ScanReg process is complete, restart your computer.
The Registry Scan utility finds and removes corrupted registry entries and system files. Those files are then replaced with a working copy of the files.
MORE INFORMATION
Renaming the Browseui.dll in the C:\Windows\System folder and extracting it from the Win_10.cab file does not fix the behavior because there are registry entries associated with the configuration of this file.
