Error on start-up

On start-up with Windows XP Pro I recieve the following error message.

Cannot find :\\.\DRI_KBFiltr

What is this and how do I repair this error?

 

Assuming you have an HP computer, and possibly upgraded to XP or XP Pro:

1. In Control Panel/Add or Remove Programs
2. Find and remove HP One-Touch Buttons
3. Ignore the message if it pops up.
4. Reboot.
5. In Control Panel/Keyboard/Hardware tab, select your keyboard and click Properties button
6. On Driver tab, click Update Driver
7. Select the 'Install from a specific location', click Next
8. Select the 'Search...' option, UNCHECK 'Search removable...', CHECK 'Include...' and enter 'C:\HP\PROGRAMS\ONETOUCH' (that's where the drivers usually are). If not there, go to the HP site.
9. After clicking Next, it should find the drivers, install them, and reboot.
