Microsoft couldn’t just let the month run out without delivering yet another cumulative update this month. Today, the company has pushed out KB4058258 (OS Build 16299.214) which happens to be the third this month. The latest update attempts to resolve the following problems:
- Addresses a compatibility issue where colors are distorted when the system is connected to displays that support wide color gamut.
- Addresses a condition where a second monitor that is connected to legacy AMD display adapters flashes after waking from sleep.
- Addresses issue that causes delays when switching keyboard languages using Alt+Shift.
- Addresses compatibility issues when rendering certain closed captions or subtitle formats during video playback.
- Addresses issue where the Microsoft Edge Allow Extension Group Policy for the disabled state was not working.
- Provides additional protections for 32-bit (x86) versions of Windows 10, version 1709.
- Resolves the issue reported by some customers on a small subset of older AMD processors where the processor entered an unbootable state after installing January 3, 2018—KB4056892 (OS Build 16299.192).
Full details: January 31, 2018—KB4058258 (OS Build 16299.214)
But, be wary of this month’s gotchas. Microsoft also lists the following known issues with this CU:
- After installing this update, some users may experience issues logging into some websites when using third-party account credentials in Microsoft Edge.
- Windows Update History reports that KB4054517 failed to install because of error 0x80070643.
- Because of an issue that affects some versions of antivirus software, this fix applies only to computers on which the antivirus ISV updated the ALLOW REGKEY.
