I don't now if this is the right community, but I hope that somebody can help me with the host of problems that recent upgrades have caused to my Win 7 Home Premium x64 SP1 installation on my Sony Vaio All-in-1 computer. I returned from a recent vacation to find a whole list of updates, security and other updates to Win 7 including to .NET services v4. After the updates my system would no longer identify my WD NAS drive under 'Network' despite the fact that I could log onto the system using the web browser interface. A restore to before my vacation undid the problem, but this was promptly lost again when the Window updates were reinstalled, during which I lost the restore point that worked. In desperation I did a clean install of Win 7 and all went well until almost the most recent updates were installed when the problem reoccurred. Hunting around on the web, I found some information that the problem could be caused by critical Windows services could being disabled. Using Black Viper’s Windows 7 Service Pack 1 Service Configurations (http://www.blackviper.com/service-configurations/black-vipers-windows-7-service-pack-1-service-configurations/) a comparison showed that the Tcp/IP Netbios helper service should have been automatically loaded, but was disabled. I enabled the service and, hey presto, access to my NAS drive was reinstated. The only problem was that further Windows updates switched it off again - the updates have, for the moment finished and the Tcp/IP Netbios helper service is enabled. However, I do not know what else has changed, e.g. other services or in the registry as I have a number of other problems that remain: 1. The list of opened programs under the Start menu was emptied after one of the updates and since then none of the programs I open are listed under the start menu; 2. A number of programs now repeatedly give UAC pop-ups when using the default setting and even setting this to one level below the the default level does not stop these: e.g. Outlook 2007 now displays a UAC menu every time it runs. Furthermore the program does not appear to be fully functional, e.g. if I try to open an archive PST file it fails to open when selected. One further piece of information, my services list two sets of services for .NET Framework services: 2 for Microsoft .NET Framework NGEN v2.0.50727 - one for x64 and one for x86 that are disabled and 2 for Microsoft .NET Framework NGEN v4.0.30319 again one for x64 and one for x86 that are enabled - is this the correct configuration? Has anybody else had similar problems with recent windows updates or can provide any assistance in providing solutions to the two problems above (I have updated the windows updates that were installed when the problems started to occur). NB the only updates during this period were from MS - all other software updates were blocked so I know that the problems originate 'chez MS'. I can provide further information if required, but at this stage do not know what further information might be helpful.
