Default Behavior

Hardware Policy Driver is a kernel device driver. In Windows 7 it is being loaded by Boot Loader before Kernel initialization. If Hardware Policy Driver fails to start, Windows 7 attempts to write the failure details into Event Log. Then Windows 7 startup should proceed and the user should be notified that the hwpolicy service is not running because of the error.

Restore Default Startup Configuration for Hardware Policy Driver

1. Run the Command Prompt as an administrator.

2. Copy the commands below, paste them into the command window and press ENTER:

sc config hwpolicy start= boot
sc start hwpolicy

3. Close the command window and restart the computer.

The hwpolicy service is using the hwpolicy.sys file that is located in the %WinDir%\System32\drivers folder. If the file is changed, damaged or deleted, you can restore its original version from Windows 7 installation media.
