Microsoft to Patch Problem Patch
slowroller writes to mention an eWeek article about a new patch to fix issues raised in their most recent release. From the article: "The company's plan is to target the rerelease only to Windows users who are affected. In a blog entry, Toulouse said the company's patch deployment technologies will have "detection logic" built into them to only offer the revised update to customers who don't have MS06-015 or are having the problem. The glitches, which Microsoft claims affect only a tiny fraction of the 120 million installations of the patch, stem from a new binary called VERCLSID.EXE that validates shell extensions before they are instantiated by the Windows Shell or Windows Explorer. On systems running Hewlett-Packard's Share-to-Web software, Sunbelt's Kerio Personal Firewall and some NVIDIA Drivers, users complained that the new binary stopped responding."
No - Microsoft doesn't release patches fast enough and they don't do adequate testing. They don't win on either count.
I know this is not a popular opinion here, but MSFT really does have a tough job, if you are objective about it, from an engineering point of view.
This issue is a bit more complicated than you think.
