A number of people have asked me if they should upgrade to Windows Vista. I reply with a quote from a wise old philosopher, Dirty Harry. "It all depends, do you feel lucky?" In honor of the Windows Vista release, here is an all Vista BugBlog Report:

Try to activate Windows Vista, and you may get an error message that includes one of these error codes:
0XC004D401 or 0x80080250
According to Microsoft, these codes show that there is an incompatibility between Vista and your antivirus software or your digital rights management (DRM) software. You'll have to upgrade that software before you can activate Vista.

It appears that Intuit QuickBooks 2006 is not compatible with Windows Vista. In this case, the blame appears to lie with Intuit, for QuickBooks uses some techniques in communicating via the Registry that violate Windows XP standards, much less the newer Vista. David Berlind covers this in a number of posts.

If you are running a Microsoft Office 2007 application on a Windows Vista computer, and you try to print to a Dell printer, your computer may lock up. Microsoft does not specify which Dell printers have a problem, but they say to check with Dell for a new printer driver. You may also want to switch things so the Dell printer is not the default printer. Keep an eye on this web page for updates.

Microsoft says that unformatted DVD-RAM disks cannot be formatted by Windows Vista. However, Vista is able to reformat a DVD-RAM disk that has already been formatted. The only workaround is to make sure you buy pre-formatted disks.

Microsoft has a list of when third-party VPN (virtual private network) clients will be available for Windows Vista. These include clients for Aventail, Checkpoint, Cisco, Citrix, F5 Networks, Juniper Networks, NCP, Nortel, and SafeNet. At this point, the majority of them are unavailable. See this page for the estimated dates.
