PSA - check if your crash logs are eating up your spare C: disk space

For whatever reason... I had "something" eating up disk space. 
 a. The moment I clear all files, C: filled up to zero spare bytes.
 b. Time and again, for weeks on end this happened to varying degrees.
 c. So I bit the bullet and dug into how to find the culprit.

Long story short:
 The Windows Crash Log directory was filled with browser crash dumps.

Many apps (including browsers) write dumps to:
 A. %LOCALAPPDATA%\CrashDumps
 B. %LOCALAPPDATA%\Microsoft\Windows\WER
 C. %PROGRAMDATA%\Microsoft\Windows\WER

If desired, you can turn off crash dumps with this admin command:
 reg add "HKLM\SOFTWARE\Microsoft\Windows\Windows Error Reporting" /v Disabled /t REG_DWORD /d 1 /f
