While the toolset has grown over the years, it started some time ago as Winternal/SysInternals and Mark Russonovich’s “Jamaicans”. You know…
- RegMon
- DiskMon
And
- FileMon
Well, some of those have been renamed and/or moved into other tools but the SysInternals suite of tools is still the best set of FREE resources for digging into why something is going sideways on a Windows Desktop or Server.
