New Log4J CVE
Read the README and the Release Notes https://github.com/CrazyKidJack/Windowslog4jClassRemover/releases/latest

Mitigating log4j in Windows?
This is fine if you only have 1 or two JAR files to deal with and you don't mind installing 7-sip to do it. However, if you have lots of JAR files, or if you don't want to install 7-zip, I created an open-source VBS script that will do it for you without needing to install any additional software. https://github.com/CrazyKidJack/Windowslog4jClassRemover

Log4j 0day being exploited
While most people that need to know probably already know enough to do what they need to do AND the information from the OP is way more complete than mine, I have not seen anyone create a Windows script that can remove the JndiLookup.class file from log4j-core JARs easily the way the zip command is able to on linux. So I thought I would post this here if anyone needs to do that... https://github.com/CrazyKidJack/Windowslog4jClassRemover

Log4J Network Scanning/Detection on a 100k+ Node Network
The last scanner type is looking for the classes. Carnegie Mellon’s CERTCC released one that is referenced by CISA: https://github.com/CERTCC/CVE-2021-44228_scanner that look for class names and some fingerprints. Then there is a scanner written in Go that checks for the vulnerable class files and their hashes (inside JARs, WARs,EARs, and zips). https://github.com/hillu/local-log4j-vuln-scanner

Log4jscanner by Google
I have been scanning with https://github.com/hillu/local-log4j-vuln-scanner and that problem was resolved in there.

So how exactly is Log4j supposed to be patched/mitigated on Windows?
If you want to scan your system for vulnerable log4j instances, https://github.com/hillu/local-log4j-vuln-scanner has binaries and is constantly updated
-
All log4j detection tools fail these cases - be careful
We are using this local log4j scanner: https://github.com/hillu/local-log4j-vuln-scanner/

Cisco AMP/Endpoint is not a great product for Endpoint Security.
https://github.com/hillu/local-log4j-vuln-scanner - Nope

Can PDQ be used to scan for log4j usage?
Log4j may be included in other jars, so a recursive ps scan like https://github.com/hillu/local-log4j-vuln-scanner may come to rescue
-
Any mitigations in the works for the log4j critical CVE?
The scanner provided by https://github.com/hillu/local-log4j-vuln-scanner gives us the following output when using "/opt/qradar/" as directory.
