Microsoft pushes Windows 10 build 10041 out to Slow ring

Clean install ISOs are also available, but problems with the corrupted Mail/People/Calendar app persist

Windows 10 spokesman Gabe Aul tweeted yesterday that Windows 10 build 10041 was heading out to the Slow ring. Shortly after, beta build 9926 users in the Slow lane began noticing the Windows 10 Technical Preview March update -- identified in the Windows Update app as fbl_impressive 10041 Professional -- appeared as an available update to 9926. If you haven't yet manually updated to build 10041, after a reboot this morning, Windows 10 will do it for you.

In my tests overnight, some updated systems exhibited the Mail/Calendar/People corruption problem described last week: mangled tiles on the Start menu that won't work, requiring a complex series of steps to get them back. In one case, though, the update left Mail, Calendar, and People intact.

If your Mail/Calendar/People apps are mangled, you can follow the PowerShell instructions in last week's article to re-enable the apps, but be aware that PowerShell is now called "Windows PowerShell" in the All Apps/Windows System list.

As soon as you run the update, there will be two new patches available:

  • KB 3050284 (which installed first on my machines) is a general patch rollup for build 10041 that solves numerous problems with the interface, and at least one common crash
  • KB 3046049, the MS15-031 SChannel patch from this month's Black Tuesday crop, fixes the FREAK vulnerability. The installation problems that have been reported with KB 3046049 don't appear to come into play with Windows 10

In addition, there's a third patch that I haven't tried yet. KB 3050279 is described as a Technical Preview for the Microsoft Surface Hub. When I find a spare wall and four big guys to schlep a Surface Hub, I'll let you know.

Microsoft has also released ISOs for build 10041. You can now perform a clean install of 10041 -- particularly handy for those of you running virtual machines. Microsoft has full instructions, including download links, on its Windows 10 Technical Preview ISO March Update page.

If you install the ISO on a physical machine (as opposed to a VM), you can either run setup.exe from inside Windows or you can boot from the ISO. For years I've recommended using the Microsoft tool for creating bootable USB drives from ISOs, but lately I've been using a free (GPL 3) utility called Rufus by Pete Batard at the Irish consulting firm Akeo. It works great.

I've been able to use the ISOs without any difficulties, although the corrupted Mail/Calendar/People app problem appears. The PowerShell hack I mentioned earlier still works. When you install the ISO, go through an update cycle (Start, Settings, Update, Find Updates) as there will be at least two new patches available -- three, if you have a Surface Hub.
