Build 19041.508 for Windows 10 May 2020 Update
The September 2020 update for Windows 10 May 2020 Update is Build 19041.508 (KB4571756), and it comes with a long list of improvements.
Even if you skipped several months’ worth of updates (cumulative or optional), you can install this latest cumulative update and you will be completely up to date.
It’s also worth noting that you might see servicing stack updates and .NET framework updates delivered separately besides these cumulative updates. Any additional update will also download and install automatically to fix potential issues in the process that allows Windows 10 to scan and install updates.
Definition updates for Windows Defender are also delivered before you install the September 2020 Update. Fixes of Defender, .NET framework and service stacking are not included in cumulative updates.
With Build 19041.508, Microsoft has finally resolved a bug that could be damaging your SSDs by running ‘defrag’ command on every system reboot.
Likewise, this update also delivers fixes for File Explorer, apps, system performance, Windows basic operations, Office products, input devices (mouse, keyboard, etc), and security improvements for storing or managing files.
May 2020 Update (version 2004) status as of September 2020
Windows 10 version 2004 update started rolling out to select consumers on May 27, but it’s still not available for everyone.
With every cumulative update, more blocks are being removed for Windows 10 May 2020 Update. After applying the September 2020 Update, Microsoft will lift the upgrade block for those who use IME input.
While it’s been a bumpy road for the version 2004, which was released three months ago, most issues are now marked as resolved.
However, in a statement, Microsoft told us that they’re investigating reports of credentials problem in Chrome, Edge, and other apps. Likewise, another bug that causes ESENT 642 warning is expected to be fixed later this year.
