How to Fix an SP DLL

1. Type 'Startup' into the search bar on your Start Menu and click the top program that appears in the list. Enter your administrative password, if necessary. Scroll through the list of programs that start when you log in and delete 'sp.dll' if it is present.
2. Press the 'Windows + R' keys to open the Run dialog and then type the command 'msconfig' into the text-entry field. Click on the 'Startup' tab and check to see if 'sp regedit -s C:\windows\sp.dll' is in the list. Uncheck its box, if it is.
3. Open Run again and enter the command 'regedit'. This will open the Windows Registry Editor. Press the 'Control + F' keys and do a search for 'sp.dll'. Delete any keys that show up as search results, but be careful not to damage any other part of the Registry.
4. Open the Windows Search program and search your entire hard drive for 'sp.dll'. Open its containing folder, select the DLL and press the 'Shift + Delete' keys to destroy it forever.
5. Open Internet Explorer and press the 'Alt' key to bring up the menu bar. Click on 'Tools' and then 'Internet Options' and switch to the 'General' tab. Delete the current homepage address, type in the address of your choice and click 'OK.'
