Using INF.DelReg/DelService to remove service key from

NTDEV
1

Hi
During uninstall I need to remove the service key from registry for my driver.
I tried below and other combinations of DelService/DelReg, but my service key in registry stays put.
Below is my inf (relevant sections).

Let me know how to use those keys or achieve above

Thx

Did you use chkinf to validate the driver *.inf file?
You need to use quotation marks in the driver Register path:
“System\CurrentControlSet\Services\MyDrv”

Thanks.
Tried with quotes and also other tags (like [DefaultUnInstall] and [DefaultUnInstall.Services]), did not help.
