  • I cannot thank you enough. I’ve had this problem on all windows computers in my home.
    After reading countless obscure forum posts as well as useless microsoft support sites it turns out this simple solution was all i needed!

  • I’ve been googling for more than a day and trying all sorts of “solutions” and I really didn’t believe yours would work because it looks so simple. But then I thought, what the heck, what else have I got to lose anyway cos a drowning man will clutch at any straw. Thank goodness I did and now the Windows Update is working! Thank you and keep up the good work!
