Hi Cody
Why, pray tell, did you try to get rid of Apache by just deleting some of the files under C:\Programme? Is that the way you normally remove software?
Is the Apache icon still available under Control panel/Software? If so, carry out the remove routine as intended. If not, do a search for any files with the letters 'httpd' and get rid of them.
If that still doesn't work, do you perhaps have a restore point prior to the moment you decided to manually delete the Apache files? If so, restore to that point and then remove Apache using the Control Panel.
I'm not on my own computer here and don't have Apache, so I can't tell you which keys to remove under regedit.
