Instead of letting Windows automatically obtain and install the updates, try visiting the Microsoft Security Bulletin site below and downloading the manual installer for each update. (It may take a while to identify and download each of the appropriate update files but it can be done.) Once downloaded, install each update one at a time, then restart if requested to do so, each time requested.. You should be able to identify the culprit or in some cases, the manual update installs correctly and fixes the issue..
Hope this helps.
for second day in row, watching my new Vaio display "Preparing to configure windows Do not turn off computer" system starts and reboots again and again. Finally did a system restore but this is a hassle. Any ideas?
