There’s a new post over on sevenforums.com that sheds some light on what is meant by the cumulative or rollup updates beginning in October for Win 7/8.1 users.
We’ve discussed that change before in an earlier thread. In retrospect it seems the details were already out there if you followed links to deeper links from lumpy95’s first post in that thread, but to be honest I missed some of the nuances that have been summarized a bit better in the new sevenforums post.
I think we all understood the individual updates were going away and would be replaced by a single cumulative update. What I now understand more clearly is there will be two versions of the updates released each Patch Tuesday–one with security-only updates, and a “monthly rollup” of security plus non-security updates.
The security-only updates are not rollups, they are an accumulation of only that one month’s security fixes. So bringing a system up to date may still involve installing multiple updates, one for each month. Also, they are not available via Windows Update, but only from WSUS via manual download from the Windows Update Catalog or (I presume) programs like WSUS Offline Update (which I’ve discussed previously).
Granted, we still can’t pick and choose which individual updates we want, but at least this gives us another option to the all-or-nothing monthly rollups.
The monthly rollups include non-security fixes as well as security fixes. They are also rollups–meaning each is cumulative from October (for security fixes, or September for non-security fixes) forward.
It’s important to note Windows Update will only offer the monthly rollup. Regardless of whether you set Windows Update to automatic or “let-me-choose”, that will be your only choice. So if you want only the security fixes, don’t use Windows Update.
At least that’s how I interpret what’s going on. If someone who is more plugged in to Microsoft sees it differently, please correct me.
