Was getting blue screen of death crashes with IRQL_NOT_LESS_OR_EQUAL when running Atlassian Sourcetree.
Did some googling to get logs of crashes
This showed in error logs D63B10C5-BB46-4990-A94F-E40B9D520160
Event Viewer - create Custom view - look for logs in last hour
This article to edit regedit and DCOMCNFG
Had to use NSUDO to run those as administrator otherwise can't edit what is needed.
