Yes, unfortunately, 99% of the time I use it for the Component hives, the other one percent are various reg exports (SxS, CBS...), basically WU stuff. Keys, Values and Data are checked. The biggest issue is that there is no rule to it. I cannot tell you EXACTLY when it happens as it does not occur the second I start the search, but for example a minute or two or five later, while I'm still researching the hive and the damn thing completely freezes but for a minute or two at this point I cannot even access Task Manager. ProcMon turns blank and crashes. And no, the hive is not corrupt because it occurs even with my healthy hive and no additional hives are loaded, just:
HKCR
HKCU
HKLM
HKU
HKCC
The steps would be:
File -> Load Hive (select the hive, name it something, but not COMPONENTS and hit enter). Then search for the Deployment/Component key in question.
