Hi ,
We had installed extension inf on PCI based base driver .
Problem in uninstallation of extension inf by using this command “pnputil /delete-driver oem112inf /uninstall”
Error says “Extension INF ‘oem159.inf’ is still in use by devices”.
Failed to uninstall driver packages. Error = 0xE000023D"
Please kindly do needful
Note: if there are two extension INF installed , then one of them can be uninstalled but not currently activated one . only way is to uninstall base INF from device manager .
Thanks
