I am trying to install the Windows 7 rollup KB3125574. Installation completes successfully and restart is successful. Eventually, on a later power on or restart, Windows fails to start.
I've tried installing this update numerous times, with antivirus on & off and with my wireless connection connected and not connected, and combinations of all four (on, off, connected, not connected). It eventually causes a boot failure every time. As far as I can tell the problem is directly related to KB3125574.
There is no obvious pattern to the start failure as far as whether it's at restart or at power on. After I began to have this problem I would attempt another installation of the rollup. Each time, when it was complete I could restart the system multiple times in a row without a problem. However, sooner or later (within a day) the system will not successfully boot into Windows.
When it fails to start the "starting windows" screen appears, the four colored dots form the windows logo panes, I see a instantaneous blue screen and the machine boots into startup repair. After a system restore the system goes back to being stable.
I understand on a fresh Windows 7 install update KB3020369 needs to be installed before KB3125574. KB3020369 is installed.
I really don't want to do a fresh Windows 7 installation if I can help it.
Can anyone please guide me to correct this problem?
