Dell proposes Logpresso's log4j scan tool (https://github.com/logpresso/CVE-2021-44228-Scanner/releases) to mitigate vulnerabilities for various product lines, until they released actual fixes (various are still pending, so we only have the scan tool).

Well it's Log4J Patch Day. Again. (2.17 now available to fix infinite recursion bug)
Peculiarly Dell for some of their data protection products also seems to advice to use a 3rd party scan tool to mitigate against certain issues in <2.14 and 2.15 log4j using log4j-scan from Logpresso https://github.com/logpresso/CVE-2021-44228-Scanner, as far as I can see a Korean company? Would have imagined Dell would also have some developers being able to write something? But that's just me...
- So how exactly is Log4j supposed to be patched/mitigated on Windows?

Scan for log4j/log4shell
It's quite tricky and there is a lot of dubious advice around. This tool is very quick: https://github.com/logpresso/CVE-2021-44228-Scanner Download a binary release from the releases section at the right of the page. I've run it over many, many, many machines so far.

how do I check if I have Log4j installed on my WINDOWS servers?
Just be aware - Logpresso scanning tool available at https://github.com/logpresso/CVE-2021-44228-Scanner. It´s quite strange that code is viewable but the binary to download is not in out control how they are made and also what they contains. I suggest everyone download the source code, review the code, build the JAR and NOT using the downloadable binares!
This tool will scan for any JAR files containing the vulnerable class file: https://github.com/logpresso/CVE-2021-44228-Scanner/releases/download/v1.2.5/logpresso-log4j2-scan-1.2.5-win64.zip
