I saw KB978542 appear as an update on Tuesday, i.e., few days ago. Since I have Windows Updates TURNED OFF, I only see updates if I manually check for them — and knowing Microsoft’s schedule I usually check every Tuesday night and then again towards the end of the week.
I didn’t check the details on KB978542 until today. Noticed that all the reported problems had to do with it clobbering Windows Mail and Outlook. So dug a bit deeper.
KB978542 is SPECIFIC to Outlook Express, Windows Mail, and Windows Live Mail. Here is the Microsoft Security Bulletin <click>.
I haven’t used Outlook or Outlook Express in over 3 years. I think Outlook is the anti-christ! I try to convince as many people that I know to stop using Outlook.
I use Web mail … but not from Microsoft. The GoDaddy version. It isn’t the greatest but it plods along, and that is good enough.
So I opted to skip (and now HIDE) KB978542.
If you are not using any of the three mail packages, I suggest you skip this update too. Appears that Windows Mail is not supposed to work with Windows 7. Those that have managed to get hacked versions to work on Windows 7 are discovering that KB978542 disables Windows Mail altogether. So be aware.
I did, however, install, per rote, the May 2010, KB890830, Windows Malicious Software Removal Tool. I do that just for the sport. I haven’t restarted the PC since … so I am keeping my ankles crossed.
That is it. Good luck.
