I've had some issues with my Samsung Ultrabook Win 8 Pro PC after accidentally installing an adware hijacker along with some other software. I have managed to remove the browser hijack but I also seem to have a windows update error. I have been trying to install Win 8.1 but it has failed and I have not been able to get windows updates fro some time as it errors out with the code "800703F1". I have tried a google search to fix it but the troubleshooting app, although it said it fixed problems, didn't. Other answers looked so varied and complicated that I thought I would try this forum as it appears to be the only one that knows what it is doing. Although I am an Administrator of the PC I don't have access to the C:\Windows\Logs directory or the C:\Windows\system32\Config so I have created zip fils of the CBS logs and the COMPONENTS file using the Administrator account. I also tried to grant myself permissions to the C:\Windows\Logs and C:\Windows\system32\config directories but this only worked for the system32\config directory... I will attach the CBS logs here as the zip file is only 2MB and use your instructions to upload the components zip file shortly. I did see some info about a possible problem with a windows patch that may have caused this issue but looking at this Forum I am assuming that this is not the case here?
