Earlier this week, we reported that Microsoft had delayed this month's patch Tuesday update, citing a "last minute issue" that has yet to be resolved by the company's engineers. Redmond declined to share an ETA at the time, but the company has since updated its blog post to announce that the February updates will be released on March 14, 2017, which is the next Patch Tuesday (via ZDNet).
It's worth noting that the company didn't share a clear explanation for the delay. ZDNet reporter Mary Jo Foley explained that "my sources told me yesterday that Microsoft was having problems with its patch build system, and that those problems resulted in the company's failure to deliver its regular Patch Tuesday patches."
For Windows 10 users, this means that you won't get a new cumulative update this month: for now, PC and mobile users on the production ring will have to keep using the build 14393.693, while those on the Release Preview ring can still download the build 14393.726. It remains to be seen if Microsoft will release a new preview build to Release Preview participants before March 14.
