If you are on the “2004” release then you should get build number 19041.844, while if you have the “20H2” release when you should get build number 19042.844 after the update is completed. Here are some of the most notable fixes and improvements in the optional update, according to Microsoft's release notes for the KB4601382 update.
The update resolves an issue with incorrect refresh rates being displayed for high dynamic range (HDR) displays, while flickering on video playback on certain low latency monitors has also been fixed.
Similarly, issues preventing the input of strings into the Input Method Editor (IME) or preventing some keyboard keys from working (such as the home, Ctrl, or left arrow keys) when you set the Japanese IME input mode to Kana have also been resolved.
Microsoft has also included fixes for screen rendering while opening games on certain unspecified hardware configurations, and an issue with incorrect languages being displayed when you sign into a console and modify the system locale. Another bug with unexpected screens showing up during the Windows Out of Box Experience (OOBE) setup screens has also been resolved.
Since the update doesn't contain and security fixes, it isn't a mandatory update and users can postpone it for the time being - these are preview builds of what will arrive as part of March's Patch Tuesday update. However, Microsoft's patch notes reveal there are quite a few fixes for bothersome Windows 10 bugs, so if you have any of the above issues, it may be a good time to hit the update button.
