When this Windows 7 Enterprise 64 bit runs software updates or uninstalls (examples; Win 7 updates, Apple Quicktime, etc) it often creates a temporary folder and places files in there to uncompress, etc which will be deleted after installation is complete. However, I now often get error messages to the effect that I do not have sufficeint permission to access the folder used (remember this is the installer making and using the folder). If I hit "retry" it usually proceeds correctly. I can also go into the C: drive directory and open the file folder which will be used but even then, I get the error message about folder permission after the OS writes a file into it.
I believe this is preventing a lot of normal updating to install correctly. If I manually install the updates (i.e. start the RUN process and then hit "retry" throughout the installation) it works. But there are probably updates I am missing and some pushed SW from Corp doesnt install at all.
