Microsoft pulls faulty Windows patch

Microsoft is pulling an update for Windows 2000 issued in this month's Patch Tuesday because it simply didn't work.

Update MS10-025 was designed to fix a flaw in Windows 2000 systems running Windows Media Services (WMS). It turns out, however, that the patch failed to mend the problem it was designed to address.

"Shortly after we released the update we received several reports that it did not protect against the vulnerability reported to us," Jerry Bryant, Microsoft's group manager of response communications writes on the Microsoft Security Response Center blog. "At that time, we pulled the update and notified customers. "The main reason for pulling the update was to save a reboot for customers who had not yet installed it."

The patch was designed to prevent hackers from taking control of affected machines, but it seems Microsoft took its eye off the ball. "The original issue was missed due to focusing on a variant of the original report early in the investigation," Bryant admits.

Microsoft says it will release a corrected version of the patch this week, and in the meantime urges Windows 2000 customers with WMS installed to apply the workaround published in this bulletin.

I'm impressed that MS are still supporting Windows 2000 after ten years!

By rjp2000 on 26 Apr 2010

That will soon change

Hi rjp2000,

It’s true that its impressive that Microsoft still supports Windows 2000 after all this time but that will soon change.

According to Microsoft, support for Windows 2000 will end on the 13th of July 2010.

See the following link:

and select the “Products listed by Product Family” link near the bottom of the page and then click “Windows 2000 Professional Edition” near the top of the new page.

Microsoft Extended Support is the final type of support a product has before it is permanently retired from support and security updates.
