This is the result of files left behind when you "remove" the software, either via Windows add/Remove Programs window, or using the HP Software uninstall utility. These files are, in my humble opinion, left behind deliberately. If you have changed brands of printer as I have, then there is absolutely no reason for any of these rogue HP files to be left behind, nor is there any reason to reinstall the HP software simply to eliminate this annoying occurance. After all, if you no longer have an HP printer, why have their software sitting on your HD taking up space and doing nothing?
The best solution to this issue is only slightly more complicated than reinstalling the HP software to get rid of the installation attempt at startup. This is how you do it:
1.) Open Windows Explorer, then click on Program Files.
Look to see if there is a folder there called "HP." If so, continue to next step. If not, then I'm afraid your only solution is to reinstall the HP software. However, I'm 99% certain that the folder will be there.
2.) After you've verified that the HP folder exists, close Windows Explorer, and reboot your computer.
You must do this to solve the problem, because you're going to be deleting the HP files which are now, even though you stopped the process, active in your computer's memory.
3.) Boot your computer in Safe Mode.
To do this, Press the "F8" key as as soon as your monitor first goes black, and before the Windows splash screen appears on your monitor. You'll be given a list of choices, simply use your up/down keys to highlight "Safe Mode," then press "Enter." Before Windows loads fully, you'll be asked if you want to enter Safe Mode, or use System Restore to repair your computer. At this window, click "Yes" to indicate you want to run in Safe Mode.
4.) Delete the HP folder from your hard drive.
When Windows has completely loaded, open Windows Explorer, and navigate back to Program Files. Find the HP folder, right click on it, and then click on "Delete." Verify that you want to delete the folder and all files. You'll be warned that some programs may not function properly, but since you're eliminating HP software anyway, this is of no concern. Simply reverify that you wish to remove the folder.
5.) Reboot your computer again.
Restart your computer normally, without going to Safe Mode. You'll find that the issue has been resolved. You can now use any registry cleaning utility to remove all traces of HP software from the registry.
The most important thing about this little explanation is the fact that I changed printers. I used to swear by HP, but I've become a Kodak convert. An added benefit to the Kodak printer I now have: Ink is about $12.00 cheaper for the combination pack than any HP ink I ever bought; and the cartridges last much longer. Their secret? HP, and most other companies, have you mount a fresh print head each time you change ink - the print head is part of the cartridge itself. Kodak has simply made the print head a seperate component, one that so far has lasted for well over a year for me with no issues. In effect, with most printer ink cartridges, you're buying a new print head each time you load a new cartridge.
And that, my friends, is just another example of how corporate America likes to rip us off...
