If this is referring to the windows driver type called a "keyboard filter driver" is a driver that sits in the keyboard data chain and can "spy" on your keystrokes before or after the windows driver handles the data.
This sounds pretty nefarious but there are actually several good uses for it. Card readers frequently use that mechanism when attached to keyboards in order to trap the characters coming off the card reader and redirect them to a special program rather than have the card data show up in a random edit field in windows for example.
Another use is for fancy keyboards with non-standard functionality that use unused scan codes and they need to trap the scan codes before the windows keyboard driver gets them.
Now the REAL way to do this would be to make the keyboards and the keyboard atached devices seperate USB devices but that is considerably more work when you could get by with a simple keyboard filter instead.
But because of the security concerns, I guess they are no longer allowing it. Which means that any peripherals that piggyback on the keyboard are probably not going to work any more :/
Well yeah the first thing to try is to see if the manufacturer has a newer driver.
It's also possible that the install of keyboard filter drivers is still allowed but only by an administrator, so you can try running the installer in administrator mode. (Right click, run as... Administrator)
It may also be allowed in the 32 bit version and not in the 64 bit version as well since the 64 bit version is supposed to be a lot more driver secure. Other than the requirement of signing, there may be other issues like this one.
I used to write keyboard filters for card readers some time ago but I don't have any way to readily test this on W7 any more.
I have pretty much the same Compaq model (CQ50 130 US) and it is having the exact same problem when I go to update to the Release Candidate of windows 7. Did you ever find a fix for this? Can the drivers for the keyboard be rolled back, or uninstalled and another version installed possibly? It halts the installation of the new O.S. and no love anywhere on the web in regards to this... I would love to test the RC, but it wont allow me to install... And my desktop is now crashed (sort-of) due to the nvidia video drivers not being compatible somehow, and the monitor is not recognizing properly... I cant get it to recognize being plugged in, and its now impossible to see anything I am doing to fix it...
Someone please save me!

What i found i kind of screwed the alert.. i did a upgrade and every driver was installed no problem, its basically like i just added a new operating system but kept everything, but maybe its just my computer i didn't do a clean install if you can try to do a upgrade it takes longer but its better than finding every driver for your laptop.. hope i helped

This keyboard filter is tied to HP/Compaqs Quick keys at the top of the keyboard for their laptops. What you want to do is remove the quick-launch software from the machine do your upgrade then install the newest quick-launch softpaq.
Sorry I didn't see this post when it went up I have been messing with two hp and a compaq laptop so I know this comes up when doing the upgrade from vista to windows 7.
