Completely disable autorun/autoplay features in Windows XP SP3 [duplicate]

Question

How to disable autorun for XP Home

I'm sure this has been answered before but I'm going to ask again because I couldn't seem to find the answer. A machine has been hit by that nasty little yt8a.exe that autoruns on boot and installs itself on other machines by using the autorun from a USB Key (Thumb Drive). How do I disable it?

Here is what I've tried:

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\policies\Explorer]
"HonorAutoRunSetting"=dword:00000001
"NoDriveTypeAutoRun"=dword:000000ff

Then on my thumb drive I setup the following Autorun.inf

[Autorun]
label=ARTest

So my logic is if autorun is in fact disabled the drive should show a generic message but it keeps showing the label ARTest so I'm assuming autorun is not turned off. Can someone please clarify. Note: I did reboot and I also installed MS's KB 953252.

Answer 1

Go to Start Menu -> Run and type gpedit.msc

There go to Computer Configuration -> Administrative Templates -> System

On the right panle, double click on Turn Off Autoplay.

On the new window, select Enabled, and on the drop down list, select All Drives. Click OK to everything and restart your computer and autorun should be disabled for good.

Answer 2

I should have mentioned the not all of the machines I have access to have the ability to do go to "gpedit.msc > Computer Configuration -> Administrative Templates -> System" which is why I was looking at the registry option.
