[ZDNet] A hidden Patch Tuesday gem: A Windows 7 hotfix rollup

[zalbard]

As part of the myriad fixes and updates that Microsoft released on March 13, this month's Patch Tuesday, is the Slow Boot Slow Login (SBSL) Hotfix Rollup for Windows 7 and Server 2008 R2. This is a rollup of 90 hotfixes that were released after SP1 for Windows 7 and Windows Server 2008 R2. These fixes improve overall performance and system reliability of both operating systems.

Not Service Pack 2, but hey, it's something.

Update (from comments to the article):

You don't necessarily have all 90 of those hotfixes

In general, Hotfixes aren't publicly available. They get created to fix a problem a user (or a bunch of users) has reported, and then delivered to that user (first for testing, and then for real). If other users report the same (or a similar) issue, then the hotfix is sent to them to try out.

Hotfixes get tested, but not to the same extent that the OS or a service pack gets tested. That's why their availability is (at least, initially) restricted.

Sometimes, hotfixes are found (over time) to be of such use and to have no deleterious side effects, and they are made more widely available (there will be a link in the corresponding KB article saying "download this hotfix to fix the problem"). Most of the time, the KB article will say "there is a fix available for this issue, contact support to get it" (for what it's worth, if there is a KB article that points to a hotfix, there isn't any charge for that support call - you are getting a bug fixed, and bug fixes are free).

Eventually, a bunch of hotfixes are rolled up together and tested as a whole. In the core Windows world this is what become Windows Service Packs. Other technologies have labeled these things as "roll up hotfixes" (they were very common in IIS and DCOM and a few other similar technologies back in the day). Roll-ups are like minor hotfixes.

So, the answer is "you are probably wrong - you may have some of these, but it's unlikely you have all of them".
