Last week, I was unable to install Microsoft updates. They failed every time. I overcame this by doing a system restore to an earlier date before the previous updates. They then installed. However I was left with Microsoft Net framework 3.5 Service pack 1 which failed to install. I went to Microsoft download site and downloaded from there. The my troubles started, in that now on opening my machine it tries to configure these updates and says on screen "configuring 3 of 3" gets to 87% then closes automatically and restarts the process overagain. I tried to open in "safemode" but exactly the same thing happens. Is there anything I can do to stop this, or am I forced in to doing a restore to factory settings, or I note that I have another option of "last known good configuration (advanced)". As I am not advanced this causes me concern. Any suggestions are most welcome.
