When you press the Windows key on your Universal Serial Bus (USB) keyboard, the key may not work.
This issue can occur if all of the following conditions exist:
To resolve this issue, contact the manufacturer of your USB keyboard to inquire about the availability of a fix for this issue.
To work around this issue, either click Start, press CTRL+ESC, or edit the System.ini file:
If a USB keyboard is the only keyboard attached to your computer when you start it, the keyboard may not be automatically identified as the correct type of keyboard. The "type=4" setting in the [Keyboard] section of the System.ini file overrides this automatic detection, so that Windows may correctly interpret the keyboard scan codes. The keyboard is being detected as an IBM AT keyboard ("type 3" to the Keyboard.drv file), instead of being detected as an extended keyboard ("type 4"). Because of this, the keyboard driver is not able to correctly process the extended scan codes that this extended keyboard type is generating.
This System.ini setting is necessary (in this example) because the normal automatic check for an extended keyboard (checking the flag at 40:96) does not indicate that this is an extended keyboard. Note that this would normally be set by the 8042 keyboard controller when your computer starts.
