```
```
ECHO.

ECHO This batch file uses WMIC when running in a "regular" Windows environment;

ECHO if it detects a Windows PE environment, where WMIC won't return video card

ECHO info, the batch file will mount the computer's HKLM registry hive, search

ECHO for the video card info, and dismount the temporary registry hive.

ECHO Screen output is identical in "regular" Windows and WinPE.
