Windows 10 November 2020 updates: What’s new and fixed

Windows 10 November 2020 update

It’s Patch Tuesday, a day when Microsoft releases security
patches for all supported versions of Windows 10. As part of
this process, Microsoft has now released Windows 10 November
2020 cumulative updates and you’ll be able to download them
using the Settings app.

Windows 10 November 2020 update is not all about bug fixes and
security improvements as it also comes with one new feature
(sort of). The new feature is a new video conferencing mode,
which allows you to use Skype directly from the desktop.

If you haven’t received the patch yet, you’ll be prompted to
download it on Wednesday morning or later. Windows 10 Patch
Tuesday updates are supposed to modify the files with potential
security issues, but the updates will be larger than 300mb if
you skipped the last optional release.

If you’re on Windows 10 October 2020 Update (20H2), you’ll be
getting the patch with Build 19042.630 and it will fix
performance issues on some devices. For those using version
2004, they’ll be getting the same update with Build 19041.630.

release:
