Having a problem with a Dell XPS 8300 and hoping someone here has the answer as I seem to have tried many potential fixes without success. Originally tried to install Office 2010 but it got about 80% of the way through and through up an error. 1935 I think. Further investigation showed that my windows updates seem to have stopped installing as well. I followed lots of advise on many websites but still had the problem. Eventually I restored the pc back to factory settings which included a format to remove any problem. Much to my surprise I am still having exactly the same issues, so far I have tried the following:- carried out numerous Microsoft "Fix it" programs ran sfc /scannow turned off Mcafee booted the pc in "clean" mode carried out repair of Net framework uninstalled and reloaded Net framework reregistered update files stopped and restarted BITS ran the system update readiness tool renamed the software distribution folder Cleared the BITS queue of any current jobs reset the contents of the catroot2 folder checked for incorrect registry values Probably several other fixes but can't remember them all. At the moment the windows update wants to install the update to the windows update but after restarting the windows update it tells me it has failed. If I turn off the pc it tells me there are numerous updates to install but it goes through the list very quickly and when it check windows update after restarting they have all failed. I am at my wits end as logically reloading windows should have sorted the issue, whatever it is. I have even ran diagnostics on memory and hard drive and both are fine. Any help would be greatly appreciated.
