    Wulog.txt & wuhistv3.log

    Per this article (last updated in 2000), Windows updates were contained in two files: Wulog.txt & wuhistv3.log. I vagely recall that that was discontinued, but can't find anything specific about it. I no longer have either of these files. Anyone know how to determine what updates you've applied & when, by looking at something on your own machine.
    Thanks,

    Probably an obvious question, but you've checked you are showing hidden files?

    Presumably there is a reason you can't revist the update site and get a history update?

    Hi Leif:
    Thanks for responding. I do have hidden files showing (but thanks for asking). I can get my history from the WU site. However, I would like to have it stored locally where I can peruse it AND I can't figure out why I don't have it. There must be a something somewhere on my computer that contains that information...I assume that the WU site is examining something on your computer when it decides what updates you don't have (although it might just be a cookie).

    Re: Wulog.txt & wuhistv3.log

    Is the absence of them interfering with Win Update's working? I guess your answer is not if I can ensure I have all the updates I downloaded. Also could you restore these files by running System File Checker?

    As far as I can tell those files you named are the ones still used because they are named in the current XP Resource Kit. Why don't you try reinstalling the Winupdmgr.exe File from the Win98_43.cab file and maybe both will show up again. See Post 315279. This comes from

    193691: WINUP: Windows Update Link on Windows 98 Start Menu Does Not Work

    Also see:

    <A target="_blank" HREF="http://support.microsoft.com/default.aspx?scid=kb;EN-US;194796">194796:
    How to Determine Your Installed Windows 98 Updates</A>

    Microsoft Windows Update Site Unavailable

    You can try these registry keys:

    HKEY_LOCAL_MACHINESOFTWAREMicrosoftUpdatesWindows 98Filelist

    I know these work for NT Kernels. Maybe there is something similar for 98:

    Hive: HKEY_LOCAL_MACHINE
    Key: SOFTWAREMicrosoftWindows NTCurrentVersionHotfix

    There will be a subkey for each hotfix that has been applied. This registry tip applies to NT, W2K and XP.
    hotfixes could also be listed at

    HKEY_LOCAL_MACHINESOFTWAREMicrosoftUpdatesWindows 2000SPX where X could be 1-4.

    Hive: HKEY_LOCAL_MACHINE
    Key: SOFTWAREMicrosoftWindows NTCurrentVersionHotfix
    There should be a subkey for each hotfix applied normally. This applies to NT, 2K, and XP.

    HKEY_LOCAL_MACHINESOFTWAREMicrosoftUpdatesWindows 2000SPX

    HKEY_LOCAL_MACHINESOFTWAREMicrosoftUpdatesWindows 2000SPX

    Hive: HKEY_LOCAL_MACHINE
    Key: SOFTWAREMicrosoftWindows NTCurrentVersionHotfix

    Re: Wulog.txt & wuhistv3.log

    After the "V4" update to Windows Update, the History file was changed to an XML file. It's name is IUHist.xml and it is generally located in the C:Program FilesWindowsUpdateV4 folder.

    There is one caveat. This only stores the updates that you have downloaded and installed directly from the Windows Update site. If you chose to downlaod the .exe file and run it later, it would not appear in this file.

    Older versions of Windows (Win98) had a program called "QFE Check" on them that also gave the user update information. There is no such file with that name on my WinXP box. I don't know if MS replaced that or simply did away with it. For nostalgia, I included an image below.

    Oh, and it certainly could not be a cookie -- that would be far too small of a file. Cookie files are of limited size and Microsoft has far too many updates! <img src=/S/smile.gif border=0 alt=smile width=15 height=15> I believe the majority of what Windows Update searches through is the registry changes made my the updates. Some of these are listed above.

    Additionally, it appears that WU may actually check the file version numbers of certain files. I have my suspicians about this latter technique (I think the whole thing is done in the registry), but others have fought long and hard to prove me wrong! <img src=/S/smile.gif border=0 alt=smile width=15 height=15>

    Thank you, R2 & everyone for your help. R2, thanks for explaining what happened to the two files & how the WU process works. I do have the IUHist.xml file & now I know I can find my update history. Thanks also for the caveat that it only lists updates from the WU site. I think the same was true with the other two files it replaced.

    SMBP, thanks for the research.
    Cheers,

    For security purposes, Phil, there have also been some changes made to the servers at their site after MSBlast and attempts at attacking Microsoft with the use of Akalmi:
