Windows XP: some updates "not found"

[DougWa]

I downloaded a two-year old version of wsus so as to get the update cache for Windows XP (x86) and while running wsus I saved the updates to a folder on a usb flash drive. While wsus was fetching updates the cmd window text said something like this a few times: "Warning: Download of http://download.microsoft.com/download/ ... kroots.exe failed".
Looking at the log I made a list of the seven updates that it didn't find and I downloaded them via browser. So now my question... can I just copy/paste the seven updates to the flash drive, and if so, into what folder?

Tell me the missing updates, then I'll tell you, where to place the files.

Great, thanks aker! I read these in a logfile as missing:
KB2789643
KB2756918
KB2832411
KB2861189
KB2378111
KB2712808
and here are the full names as downloaded by browser from Microsoft:
NDP20SP2-KB2789643-x86.exe
NDP30SP2-KB2756918-x86.exe
NDP30SP2-KB2832411-x86.exe
NDP30SP2-KB2861189-x86.exe
Windows6.0-KB2378111-x86.msu
Windows6.1-KB2712808-x86.msu
ps: Should I worry about the missing download for "rvkroots.exe"?

All NDP-patches listed here go to .\client\dotnet\x86-glb; the Windows6.0 one to .\client\w60\glb and the Windows6.1 one to .\client\w61\glb. rvkroots.exe is nothing you should worry about.
