IE9 & WSUS

The RC shouldn't be avliable via Windows update as yet, a Release Candidate is usually the first release for public testing but is still a beta release. There will still be some time before it releases to manufacture.

When it finally does relase, it should simply be a case of not approving the update for as long as you require.

Previously MS released a blocker tool, which added a registry entry to machines to block the ie8 update. They may release the same again for ie9.

I assume update rollups should be unticked to ensure the update does not get automatically approved and installed then?

I don't think the update rollups apply in this case as it's a completely new version.

Technically I think update rollups are bundles of small fixes put together for easier updating.

I've just had a look, and IE 8 in my WSUS is classified as an 'Update Rollup'. All subsequent IE 8 updates are in 'Security updates'.

as firth though, blocked update rollups.
