Windows 10: October Cumulative Update

After installing october cumulative update, I have faced problems with my graphics drivers BSoDs, black screens, graphical glitches, then I tried installing the Insider version of 20H2, yet to no avail, now I can't revert back to before the cumulative update nor before the 20H2 update as it has been more than a month. How can I revert back to the windows version available to end consumer in September without losing my personal files?

Microsoft controversially brings cumulative updates to W7 & W8.1

So much for October. My server, the W7 box, and the W8.1 machines in the house all did Cumulative Updates today, outside of the normal patch cycle.

Nothing new on the W10 boxes, which is why I think it is this schedule that @qubit did the OP on.

 

Cumulative Update KB4520062 Windows 10 v1809 Build 17763.832 - Oct. 15 Win Update

Well:

Microsoft Defender Advanced Threat Protection might stop running
The Microsoft Defender Advanced Threat Protection (ATP) service might stop running and might fail to send reporting data. You might also receive a 0xc0000409 error in Event Viewer on MsSense.exe.
Affected platforms:

• Client: Windows 10, version 1809; Windows 10 Enterprise LTSC 2019
  
• Server: Windows Server, version 1809; Windows Server 2019
  

Next steps: At this time, we suggest that devices in an affected environment do not install KB4520062. We are working on a resolution and estimate a solution will be available in mid-November.

Intel Gives Core i3 and Core i5 Dual-Core Processors K0 Stepping Update

Intel is giving some existing 32 nm "Clarkdale" based Core i3 and Core i5 processors an update. The processors will transition to the new K0 stepping from the existing C2 stepping. The parts that will be made on the K0 silicon are Core i3 models 530 (new sSPEC: SLBX7), 540 (new sSPEC: SLBTD) and Core i5 models 650 (new sSPEC: SLBTJ), 660/661 (SLBTK/SLBTB), 670 (SLBTL). Newer and upcoming models such as the i3-550, i3-560, i5-665K, and i5-680 are already being built on the K0 stepping die. Motherboards will require a BIOS update to support the new K0 stepping processors.

The K0 stepping change includes the following highlights:

• New S-spec and MM numbers for the converting products
• Extended CPUID will change from 0x00020652 to 0x00020655
• Host RevID will change from 0x12 to 0x18
• K0 stepping package is pin compatible with C2 stepping package
• Adds Processor Context ID (PCID) support

The revised older SKUs that are built on K0 stepping will be market-available by October 16.
