Have a Dell Inspirion 1150 which lost the schlwapi.dll file. Can I use any copy of xp pro to repair or does it have to be the original on laptop? I know it will ask for the cd key and the party failed to drop it off this morning. All I Have is Microsoft Office. Guess they thought this was the OS. I have xp pro myself on my system.. I do have the schlwapi.dll file on a thumb drive but I cannot access windows........ safe mode either.......... Thanks
