Not sure exactly what happened. I did a search on the computer. the lpk.dll is in the system32 file. so why does it keep popping up no matter what program I want to run. Every one of them says a file name and then system error. I tried to restore to an earlier date, but this does not fix the problem. I ran Superantispyware and it did not fix the problem. I was able to do this in safe mode with networking, which is where I am now. I ran the windows updates today, and was attempting to get the new ie 10, and it hung up so I shut the computer down and hoped that it would straighten itself out. When I returned I could not get on the internet. I checked the router and it was just fine. What is this lpk.dll??? anyone have any ideas what has caused this, and are there any for sure cures??
