4 PCs in 3 different companies have developed the same fault.
They can get to the welcome / login screen and once logged in they get no desktop and no taskbar (startmenu).
Ctrl-Alt-Del brings up the taskmanager and we can run the explorer.exe direct but get only a browsing window and no start menu or icons.
We have tried Anti-Virus Scans, Anti-Spyware, Anti-Rootkit, uninstall of recent XP updates & replaced explorer.exe and SFC /scannow all to no avail.
Our only option is a fresh install, but without knowing what the issue is it may re-appear and it seems more PCs may fall under the same issue.
We searches suggest a virus/malware but nothing seems to pick it up. Running in Safe Mode give the same issue, no icons or taskbar. System restore does not work and Last Know Good Config.
Basically we are stumped.
