After you install the latest Windows NT version 4.0 Service Pack, runningthe utility Ntregmon.exe 1.1 will cause Windows NT to crashdump with a STOP0x0000001E error in the driver Regsys.sys.
The Regsys.sys device driver that comes with NTREGMON directly accessesdata structures internal to Windows NT. This type of access to the datastructures is illegal. Anytime there is an update to Windows NT there is apossibility that these internal data structures will change. These changesresult in the driver creating or utilizing invalid pointers and causing thecrashdump.
NTREGMON is manufactured by a vendor independent of Microsoft; we make nowarranty, implied or otherwise, regarding this product's performance orreliability.
