After reading the advice on this site I modified some of the Windows Services settings. After re-booting some strange things have occurred.
It takes an absolute age to restart, folders and programs do not minimze to the taskbar, image files do not open, it does not recognize printers or network connections.
When I open the Services folder, under the Extended tab no services are listed. On the Standard tab they are all listed, but cannot be modified (right click/properties nothing happens).
I have since downloaded the XP SP3 default services batch file and ran it, but are still having the same problems.
Any suggestions ?
Cheers
