16 Bit Windows Sub system

By geffrey_m ·
I am getting an error message when I try to run
a command prompt on Win2k professional. Virtual
device driver format in the registry is invalid.

I have already searched, read and tried the fix
from microsoft article #Q254914, but when
I drill down to the HKLM\System\CurrCtlSet\Control\VirtualDeviceDrvr
I do not have the vdd key they discuss to delete.
I tried adding it as per the instructions, but
when I try to add it, it says the key already
exists, change the name. How can it exist if
I cannot see it. I did try searching from the top down, and there was a vdd key in another place. Any ideas? Thx

16 Bit Windows Sub system

by Joseph Moore In reply to 16 Bit Windows Sub system

The Technet article says to delete the VDD entry. Remember, VDD is NOT a key (folder). It is an entry in the VirtualDeviceDrivers key. When you open REGEDT32 and navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\VirtualDeviceDrivers
you will see VDD in the right pane.

Look there and follow the Technet article instructions.

hope this helps
