I hit below error/blue screen when trying to install MSSQL 2005 Express in a Microsoft XP pro SP2 machine:
STOP: c000021a (Fatal System error)
The windows subsystem system process terminated unexpectedly with a status 0xc0000005 (0x7c9106c3 0x0053ec24)
Try for 3 times to reinstall windows and no luck. Hit the same error when installing MSSQL 2005 Express.
Finally found an forum
