Microsoft has removed the latest Windows 10 Mobile build it made available to Lumia 950 and 950 XL users due to installation problems.

A Microsoft Answers forum moderator acknowledged Microsoft had unpublished Windows 10 Mobile build 10586.29 from its public update servers due to a variety of problems experienced by some of those trying to put the latest release on their Windows 10 phones.(Thanks to Johan van Mierlo for the link to the post.)

While some Lumia 950 XL users said they were unable to install the 10586.29 build since December 8 -- the date that Microsoft made it generally available -- it wasn't until yesterday that Microsoft officials said that it would be pulled.

From yesterday's Microsoft Answers post by Mike Mongeau, forum moderator:

"We are aware of issues related to the recently published Windows 10 Mobile update, including: update not being offered, update appearing to get stuck at 0%, and pesky low storage notifications. The team is working on fixes and improvements to the upgrade experience in the short term and with future releases. In the meantime, we have unpublished the 10586.29 update for Windows 10 Mobile from our public update servers while we work through these reports.

"For those of you who still see the low storage notification: while bothersome you can safely ignore this message.

"For those of you who still have pending updates (OS or apps): make sure to plug your phone into a charger and leave untouched while it works through those items."

Those who have successfully updated their Lumia 950 and 950 XL devices to 10586.29 won't be affected by Microsoft's move.

I've asked Microsoft officials if they have an estimate as to when they may republish the 10586.29 build. No word back so far.

Windows 10 Mobile 10586.29 was the first cumulative update to the Windows 10 Mobile build that Microsoft delivered on its first Windows 10 handsets. Microsoft made 10586.29 generally available a couple of days after Windows Insiders got the build for testing.

Microsoft also released simultaneously a 10586.29 build of Windows 10 for PCs and tablets to the general public on December 8.

Microsoft officials have said earlier this year that they expected Windows 10 Mobile to be rolled out to Windows Phone 8.1 users as an over-the-air update starting in December 2015.

Update (December 16): A Microsoft spokesperson emailed me last night to let me know 10586.29 is back and available for download. The official statement:

"After momentarily pausing the Windows 10 Mobile update due to an issue with the update server that impacted the installation of the update on a limited number of phones, we have addressed the issue and will begin rolling out the 10586.29 update again."
