Remove backslashes in CommandLine for sticky key rule 
Example command line is exactly "cmd.exe sethc.exe 211".
=> the detection with *\cmd.exe... would not match.

Create win_etw_trace_evasion.yml 
there are two versions of clear and two variations of set that can be used with something like wevtutil
`wevtutil cl | wevtutil clear-log | wevtutil sl | wevtutil set-log `

Also, I am adding a `*` match at the end, because there are other parameters that could be placed on the end -- so unless this was used on a general search on a text/analyzed field then the `*` is necessary.

example `wevtutil set-log Microsoft-Windows-WMI-Activity/Trace /e:disable /q:true`

Expired happens too often 
Back then when we created this rule, we noticed that "logon attempt with expired account" happens pretty often, so we decided to not include it. All event codes in this rule did not appear in a 30 day time period and therefore the rule's "level" was set to "high".

Create win_susp_bcdedit 
This is a more general rule for possible boot/mbr value edits using bcdedit that I have seen in the wild.
It is different than 3288f6425b/rules/windows/malware/win_mal_wannacry.yml
because it is not specific to anyone family (of malware) and also has different CLI options
