dxdllreg.exe

After installing the latest DirectX update from Microsoft, a number of Win2K PCs are experiencing slow performance issues. I’m making an educated guess it’s the update because when I look at the Process tab in Task Mgr, it shows dxdllreg.exe tying up the cpu. When I end the process, the PC performs normally again. I did a search on the MS KB and nothing relevant showed up. Any advice is appreciated.
