Not just slow update "scanning"
Just wanted to add to my 1st post, I was talking more about the actual Windows 7 machine overall performance not the long "Scanning for updates" which is a well known issue.
I have a few W7 machines at home that I keep a very close eye on as they are for audio applications (DJ'n, sequencing, audio transcoding and audio processing). These machines were installed by me manually and I am very fussy about the installs (correct up-to-date drivers, fine tuned asio etc).
These machines are now starting to show application performance degradation, and all the machines are unique (different makes, models and software from each other).
Not 100% sure this is down to 1 update or patch as they seem to have gotten slower over the last month or so, not so much over night.
Biting the hand that feeds IT
