To start, to be on the safe side, you'll want to record information on where the files that you're about to delete are located. You could write it down on a piece of paper, but there will be semi-long strings of text with odd punctuation that needs to be replicated exactly if on the off chance, you have to put these back. So I'd recommend saving the info in Notepad or Word, then deleting it once you know everything works fine.
First of all, you need to find the StartUp folder. Mine is located here:
Start --> Programs --> StartUp
Just take a look the files in there. Probably a couple of them will start with "HP" or maybe "Hewlitt-Packard."
Point your mouse over the first one, then right-click it. A menu will pop up. Click on "Properties." An information screen should pop up that looks something like this:
Highlight all of the text in the "Target" field (as shown above) and press Ctrl+C to copy it. Then go to your Notepad or Word file and paste it in there (Ctrl+V).
Also highlight all of the text in the "Start in" field (when I did this with my HP files, it was much longer than the above example). Paste that in there along with the "Target" information. You might want to note which is which in the file, as well.
Finally, make a note of what the "Run" field says. You can't highlight and copy this one, as it's a drop-down menu. Just type a note of what the field is.
All right. Click OK, then go back to the step where you look through the StartUp menu. Get the same information for the next HP file. And the third, and so on until you're out of HP files. Save the information you've copied down.
Ready? It's time to delete the shortcuts from the StartUp menu. Go to the StartUp menu and highlight one of the HP files. Right-click it so the menu will pop up again. This time, click "Delete." A box will come up that says, "Are you sure you want to send [NAME OF FILE] to the Recycle Bin? Click Yes. Then do that for the other HP files.
You're done! Restart the computer -- Windows should load more quickly than before. As a safety precaution, don't empty the Recycle Bin until you've tried to print something and you've verified that the printer works fine.
That should do it. Let me know if anything goes wrong.
