Windows 7 Ultimate 64, here
all patches have worked without issue
all new versions have worked without issue ( since last May of last year 2009)
as far as loading up / installing / patching / updating correctly.......
OOZ662, 
your problem sounds like something I had posted regarding Windows 7 on some systems hanging programs / or using memory / or possible memory leak  ( posted in the Hardware  & Software Forum about it awhile back )
possibly........ might be something else all together.....  sorry can't offer you anymore than that
