  1. i have an HP laptop and run VISTA HOME PREMIUM for an OS.
    when attempting to update my WINDOWS UPDATE (WHICH IS NOT SET ON AUTOMATIC), I keep getting a “WINDOWS UPDATE ERROR 80072efe”.
    an additional window popsup stating “WINDOWS HOST PROCESS HAS STOPPED WORKING”
    this has made my browser very unstable (flashes and opens more than one browser page…tab…window…etc..)
    if you can, please tell me how to rectify this issue.
    thank you so much for listening and thank you in advance for your help

  2. Well the first thing this Fix It app told me to do was that it required XP SP3 to run, so it told me to update to SP3 then re-run the Fix It. WINDOWS UPDATE is not working after a brand new XP/SP2 install. That’s why I’m running this Fix It, so how am I supposed to update to SP3?

  3. why does the windows 10 package have a problem with updates and refers me back to my internet connection all the time but I am connected by mobile connection which is the only way I can connect in the bush. How do I improve the performance on a mobile connection ?

    thank you await you comments with eager anticipation.

    also why does the office package I purchased with the new notebook not want to run on windows 10
