Uninstalling Sophos W10 Dell Laptop

Hello Gary,

Thank you for reaching out to the Sophos Community. In order to assist in the removal process, I recommend using the "Sophos Zap" tool, instead of attempting a normal uninstall.

One way you can ensure Tamper Protection is being disabled is as follows. 

- Obtain the Tamper Protection Passcode from Sophos Central
- On the local machine open Command Prompt as Administrator and enter the following (without the dash at the beginning)
- cd C:\Program Files\Sophos\Endpoint Defense\
- SEDcli.exe -tpoff <passcode> 

You will enter the digits of the passcode where <passcode> is present above. If the command returns "Incorrect SED  Tamper Protection password provided" you will need to use the following KBA prior to attempting the Sophos Zap tool.

Thank yo for the advice - however, when I try to disable tamper protection using the steps above I receive the message "Access to SED Tamper Protection status was denied".  I have re-checked tamper protection passcode via Sophos Central and the passcode used is the right one.

Can you clarify if I should use the next solution as provided above i.e. "......the following KBA prior to attempting the Sophos Zap tool.

I wait to hear from  you

Hello Gary,

When trying this on my side I am returned "Access to SED Tamper Protection status was denied" only when the Command-Prompt window is not launched as "Administrator". Can you confirm if this is being done prior to running the commands? 

- From the Windows Start menu type "CMD"
- Right-click on the "Command Prompt" option and select "Run as Administrator" 

If you are still seeing access denied errors being returned, then it is recommended to use the "Recover a tamper protected system" KBA you linked above.
