Customer's pc will boot to the desktop without icons or taskbar. Ctl-alt-del brings up Tasakmgr, but running explorer.exe does not help. Most programs will not run (Mbam; HJT; etc.) but some will - (Spybot; Rogue Remover; IEDef Fix etc.). Safe mode (any flavour) boots to the Welcome screen then freezes. Msconfig will not run. Client does not want to format/re-install.
What I have done:
1) Boot from UBCD, run SuperAntiSpyware; remove some Trojans;
2) Repair install of XP ;
3) Run Spybot, remove some infections;
4) Run RegRestore from UBCD, choosing a Restore Point when the client confirms the pc was running normally;
5) Confirmed Registry entries via regedit ('Shell' has a value of 'explorer.exe' etc.);
I'm out of ideas...Any suggestions?
PC is a Dell Dimension 1100 running Win XP Home SP2
