Right click on Start > Search. Type rundll32.exe in the field for files to be searched for. Choose to search your primary drive (usually C). Enable Search Hidden Files and Folder from Advanced Features. Click on Search button to begin the search. In the list of results, locate the rundll32 file associated with C:\WINDOWS\ServicePackFiles\i386. Right click on rundll32 to the left of the aformentioned directory and choose "Open folder location". The rundll32.exe file should be hightlighted when the folder opens. Right click on the file and choose copy. Next, in the search results list, right click on rundll32 that corresponds to C\Windows\system32\rundll32.exe and choose "Open folder location". Again the file should be highlighted. Right click on the file and choose delete. Right click again in a free space within the folder and choose paste. If this does not solve your problem you may need to get a windows os disk and extract the file from there.Sometimes deciding which battle to fight is the toughest battle of all..
