Remove failed VPC Additions

Have you ever tried installing the VPC Additions of the 5.x Version on Longhorn?

I have. After I run setup.exe in XP Compatibly mode and I restarted, Longhorn hanged in an endless loop. I don't wanted to reinstall it, so I decided to getting it back with some registry tweaks.

First, it is also not possible to run in safe mode, because the VPC keyboard and mouse driver doesn't work. You need to boot from a WinPE or a second working NT5 (XP/2003/Longhorn).

1. Type Start -> Run... -> regedit

2. Click on HKEY_LOCAL_MACHINE, then File -> Load hive..., select the file "system" found in system32\config of your broken Longhorn. Press OK and enter a name for the hive tree (WinLH or something).

3. Look in ControlSet001\Services\i8042prt an replace "vpc-8042.sys" with "i8042prt.sys". Look also in other available ControlSets (ControlSet002, ControlSet003 etc.)

4. Now you should be able to boot in safe mode.

5. Back in Longhorn safe mode, open the Device Manager and delete the networking card, keyboard, mouse and display adapter.

6. Now it should be done.

If you can't boot Longhorn with this modifications:

7. You should go back to the second NT5 and repeat steps 1 and 2.

8. Delete this registry entries:

ControlSet001\Enum\Root\LEGACY_MRXVPC

ControlSet001\Enum\Root\LEGACY_VPCMAP

ControlSet001\Services\1-driver-vpcsrvc

ControlSet001\Services\1-vpcsrvc

ControlSet001\Services\MRxVPC

ControlSet001\Services\VPCMap

Look also in other available ControlSets (ControlSet002, ControlSet003 etc.)

9. Delete these files:

CNTX\VPCSRVC.SYS

CNTX\VPCSRVC.EXE

system32\MRxVPCNP.dll

system32\VPCMap.exe

system32\drivers\mrxvpc.sys

system32\drivers\vpc-8042.sys

Get sound and graphics card driver

Just take add this files from WinXP to a virtual or real floppy disk:

From WINDOWS\INF or I386:

display.inf

s3nb.inf

s3sav3d.inf

s3sav4.inf

s3savmx.inf

s3trio3d.inf

sbp2.inf

wave.inf

wdma_csc.inf

wdma_ctl.inf

wdma10k1.inf

From drivers.cab:

ctlsb16.sys

s3legacy.dll

s3legacy.sys

Then use these during the driver installation with "Have disk..."
