I installed it on my work PC a day or two ago. Haven't had any problems with it whatsoever.
 
I'd recommend installing it on any Windows 2000 SP4 PC as Microsoft have stated that there are certain bug/security updates in the Rollup that will not be made available individually through Windows Update.

That's reassuring, Ross.
 
Hitherto, when I've added Windows updates, I've avoided the following ones, because they've been accused by some Win2K users of being implicated in new Win2K bugs:
 
KB893066
KB839643
Q329170
KB835732
 
However, if you now install the Rollup, those four are automatically included.
 
Are any or all of those four updates now listed in your Windows directory, Ross? Only the uninstallable ones will show, of course. Look in either Add/Remove Programs or in the first part of the WINNT folder.
 
 

I've checked again.
 
893066 is still a separate update that I can download and install; it's not contained in the Rollup. 893066 is a fix which returns the default size of the TCP Receive Window in Win2K to 17,520 bytes. According to some experiments I did with the utility DrTCP a month or two ago, the optimum TRW on my Win2K machine is 32,767 bytes. Okay then, so that's not a problem. MS have at least given the option of downloading that separately.
 
Somehow, 839643 has already got installed on my machine. Ah well, never mind.
 
As for 329170 and 835732, I can find no reference to them now, either on my machine or in the Rollup. They might have got installed on my machine in some indirect way some time ago and perhaps are uninstallable fixes.
 
 

Packman,
 
Just to let you know, I have got the 893066, 839643 & 835732 updates installed. I've checked the Rollup 1 KB Article and all three of these updates are indeed included (and still available seperately).
 
As for patch 329170 (Windows 2000 Security Patch: Flaw in SMB Signing Could Enable Group Policy to be Modified), there's info about it here. Also, Microsoft have included this update in recent 2000/XP Service Packs.
 
Hope this helps.

Ross,
 
I scrolled right through the long list of bug fixes in the Rollup but couldn't spot those particular ones. Perhaps I couldn't see the wood for the trees? Or perhaps they simply don't appear in my particular list because they're already installed on my machine?
 
You infer that having those particular fixes has not impaired the functioning of your system in any way (presumably, a Win2KSP4 system). True?

Packman,

Yup, my work PC is SP4'ed up. In all honesty, I've never had any problems with any updates for Windows 2000... maybe I've been lucky.

Those are just the security patches, Ross. At the Windows Update site you can view a description of the Rollup, if you're offered the Rollup. In that description, you can find a link to a very long list of bug fixes in the Rollup. That list is a quite separate one to the one you've shown, which is only of the security fixes.

It certainly used to be the case that if you already had a number of Win2K security updates or bug-fixes installed and you then installed SP3 or SP4 on the top, it really screwed up your system. And there was no going back. So, why is this Rollup any different?
 
It seems to me that you need to be extremely careful that, by choosing the Rollup, you don't end up installing a number of updates that you've already got. Fine if each person gets a customised Rollup but MS haven't said that that's the case.
