TrendMicro OFFiCESCAN Uninstall w/o Password


To All our Clients

We received lots of inquires about how to uninstall the client-side antivirus program “Trend Micro OfficeScan” without the need to enter a password.

To do that is very simple & “be careful when changing registries”


For Windows XP

To open registry, go to Start and select Run.
Type regedit in the window and click “OK“.

registry window will open then proceed to step 2.


For Windows Vista

Click on Start and type regedit in the window.
Click on Continue in the next window to open the registry.
then proceed to step 2.


change registry at:
hklm/software/trendmicro/pc-cillinntcorp/currentversion/misc./Allow Uninstall
from 0 to 1
then there will be no password question any more

now go back to Add/Remove Programs and uninstall your software. :)
