    Hi All,

    After the 02/09/2010 updates went on, I am getting calls
    from customers complaining about massive slowdowns.

    From my initial research, I have found that if I copy
    a file they are having trouble opening on the network to
    their desktop, the slowdown vanishes. The slowdown
    only occurs when trying to open a file, such as an
    Excel spreadsheet, from the network. What should
    take 1 second, takes 10 to 15 seconds.

    Now, two of the three, business users complaining
    are using Samba (Linux) for their file server.
    So, no Microsoft patches on those servers. The
    third business is using peer to peer. All
    of the workstations are using XP-Pro-SP3.

    Most of the XP workstations are running Kaspersky
    Word Space Security (KWSS): kav6.0.4.1212_winwksen.exe.
    Some prior versions of KWSS too. Both pausing
    and exiting KWSS does not change the symptom.

    I am seeing these as the (XP) update on 02/09/2010:

    KB977165 <-- heard this one causes BSOD's
    (did I miss any?)

    I am about to start uninstalling them one at a time,
    but thought I'd ask the groups first what they thought.
    Be nice if I only had to uninstall one. Tons of rebooting
    the other way. :'(

    Many thanks,

  2. Hello ToddAndMargo,

    I cannot confirim the problems you describe, we didn't have any problems
    on XP clients or with slowed down network after installing the updates.

    Best regards

  3. Just to Clarify that Update does NOT cause a BSOD
    However when a System is Infected with a certain Malware
    and the update is installed
    it affects the booting process.

    Please do not post that this update causes a BSOD
    It's the Infected PC that causes the issue not the other way around

    Hi Russ,

    Do you know which malware is causing the BSOD's
    with KB977165? Even though I am not getting BSOD's,
    I'd like to specifically check for it.

    Many thanks,

    Did a quick test from an XP VM to a Linux server, and saw no obvious problems
    after the update. It may of course be this problem is specific to other

    Just a thought, though, check your problem isn't caused by LAN card
    powersave. This sometimes gets turned back on when any major system-change is

    From the technet writeup it seems this patch relates to escalation of
    priveleges for a locally logged-on user. Therefore (AFAICS) only of high
    concern if malware or a malicious user already has system-access.

    More good I have about ten more workstations
    with KB977165 removed and happy camping has returned.

    And, more good I also checked with Kaspersky
    and we can find no sign of any infection.
