Hi Keshav,
This is a complete mystery, it really is...
Create a new text file on your Desktop and paste this text into that file
@echo off
set Folder=c:\Windows\System32\Tasks
set Log="%UserProfile%\Desktop\Shutdown.txt"
echo Files containing "shutdown": > %Log%
dir /b /s /a-d %Folder% > "%temp%\Tasks.txt"
for /F "delims=" %%a in ('type "%temp%\Tasks.txt"') do (
type "%%a" | find /i "shutdown" && echo %%a >> %Log%
)
Save that file and on the save as dialog, set file type to all files, then save that file as test.bat
Then right click that file on your Desktop and select 'Run as Administrator'
When that script completes, there should be another new file on he Desktop named Shutdown.txt
Open the file, what text is in that file?
