Found this on a forum:
Joel,
Another forum user, Troy A. Tudor, posted a fix for the DRI_KBFltr problem.
Here it is:
I had this problem upgrading from XP Home to XP Pro. Found in the registry it's
linked to the Quick Launch keys. Follow these steps:
1. In Control Panel/Add or Remove Programs
2. Find and remove HP One-Touch Buttons
3. I had the message pop up again during removal. Ignore it.
4. I didn't reboot but probably a good idea.
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 were on my 5475)
9. After clicking Next, it should find the drivers, install them, reboot, and mine
works perfectly now.
