After upgrading to XP you get the message cannot find the file \\.\DRI_KBFiltr when booting HP laptop.
If your keyboard is supported by XP, try uninstalling and let XP detect it. If you do not get the error message when you reboot, you do not need to do the below. But you may need to reinstall the software to get the buttons to work.
This is related to the keyboard.
1.. Go to Control Panel, Add/Remove Programs, remove HP One-Touch Buttons
2.. Go to Control Panel, Keyboard, Hardware tab, select your keyboard and click
Properties button.
3.. On Driver tab, click Update Driver.
4.. Select the "Install from a specific location", click Next.
5.. Select the "Search for best driver in these locations" option.
6.. Uncheck "Search removable media (floppy, CD-ROM..)", folder after the upgrade.
7.. After clicking Next, it should find the drivers, install them, reboot.
