[pc30]

(Windows 7)My all destop icons,start menu and task bar is missing.In the log on,the computer menu appears.I can my works from it,but I want the destop,star menu and task bar again.If I run the "explorer.exe" on the task manager,only another computer menu appears.
(I installed avira antivirus on the last week,scanned the machine,and quaratined some file that avira said me the viruses.I checked them later and I recognized some of they are system32 files.I restored them and restarted,but the question continues.)What can I do?

try system restore if its turned on

or if you want to try this

run new task in task manager---regedit

navigate to

hkey local machine

software

microsoft

windows nt

current version

winlogon

select winlogon and in right side panel double click shell

make sure bottom value says explorer.exe

even if it does delete the words explorer.exe and retype them then press ok

may have to restart pc afterwards
