How to Uninstall and Remove OEM BIOS Emulation Driver Activation Exploit/Crack
Microsoft calls Paradox OEM BIOS Emulation OEM Toolkit as OEM driver activation exploit. Whatever is the name, the exploit is a Vista activation crack that bypass product activation. Microsoft said the driver program interferes with standard Windows operation, and thus the exploit has to be removed. In fact, Microsoft has rolled out KB940510 detector via Windows Update that scans the system to catch these exploits.
However, the detector yet to be able to automatically remove the exploits found. However, Microsoft provides removal instructions in KB948253 that is similar to uninstallation guide for Paradox OEM BIOS Emulation Toolkit. The removal instructions of Microsoft also reset the WGAER_W (the WGA exploit detector) status.
To remove the OEM driver activation exploit
- Locate the Royal.sys file in the following folder:
Drive:\Windows\System32\drivers
Note Drive represents the drive on which Windows Vista is installed.
- Delete the Royal.sys file.
- Determine whether the following folder exists on the system:
Drive:\Windows\System32\DRVSTORE\royal_*<followed by many numbers>
If it exists, delete the royal_* folder.
- Click Start button, type regedit in the Start Search box, and then click regedit in the Programs list. If you are prompted for an administrator password or for confirmation, type your password, or click Continue.
- Locate the following registry subkey, and then right-click it:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\OemBiosDevice
- Click Delete to delete this subkey.
- Locate the following registry subkey, and then right-click it:
HKEY_LOCAL_MACHINE\Software\Microsoft\Genuine Advantage\WGAER_W\GenuineInfo

Note that you may need to enable the Show hidden files option, and then disable the Hide Protected Operating System Files option in Folder and Layout Options’ Advanced Settings to view the files required to be deleted.

Does MS look only for Royal.sys?
What happens if you rename it for, let’s say, Loyal.sys and correct all the registry entries to reflect this change.
Has anybody tried this?
Will “Loyal.sys” be transparent to Microsoft?

I actually thought that the whole idea of the paradox oem activator was to install it… not to remove it…
Damn, was I wrong or what

Actually, this was THE thing which made me move from windoze to MacBook PRO :-). One day, Vista told me I’m done with my notebook - it was correct at the end of day, as I didn’t pay for the bogous OS from MS, I tried it a few months instead of my XP, which was a BIG mistake.
Anybody reading this: consider moving to Apple - I never had one, 1 month is over now with my MacBook PRO 17″ and I LOVE IT, just can’t compare it to the stupid Toshiba Satelite with Vista. The HW rocks, the OS is very friendly, TimeMachine does all the backuping for me, everything runs smoothly.
Forget the silly activation and stupid Vista with all those bugs, performance problems etc. You know what? My newest web camera I bought because of Vista (my Philips was not working anymore..) is not working under Leopard, but my old Philips is :-). Funny thing.
Peace,
