We currently have Zenworks 10.2

We want to uninstall patch 971029 - Disable Autorun for USB drives in Win Xp
because we have remote users who backup their data to USB thumb drive using a batch file on the drive.

We went into ZCM and then Management Zone Settings->Device Management->Zenworks Explorer Configuration->General

and select Uninstall unassigned bundles after 10 days.

We also went into patch management and disabled the patch for Windows XP.

But well after 20 days from disabling the patch, I still have most machines still have it.
Most machines have refreshed over the last 24 hours.

Firstly, is this this the correct way to remove a patch?
Or is there another way to remove it without having to create an uninstall bundle?
