As we have reported earlier, Microsoft is fast testing internally lot of builds for Redstone 1 and Redstone 2. The company is already testing a new Cumulative Update for Redstone 1, now reports are coming in that the company is internally testing a new Cumulative Update for Threshold Branch.
The company is testing a new Cumulative Update 10586.639 for its Threshold Branch for Windows 10 and Windows 10 Mobile which has been compiled on Friday 14th October.
Its been more than a month since the company has released any new Cumulative Update to its Threshold Branch. Currently we are not sure as to what fixes will be coming with the new Cumulative Update for Threshold Branch.
If the company does not find any issues with the CU during internal testing then we could see the build getting released to Threshold Branch in the coming week which is being currently at .545 which was the last released build.
