ShowAccs can examine the registry in approximately five minutes.
Walking through the entire registry or file system, however, might
require many hours, depending on the size of the file system and
the scope of analysis. Examining every ACL on every file and
converting security identifiers (SIDs) on a large file system of
roughly 50 gigabytes (GB) can take two or more hours with 100
percent CPU utilization.
Before running the Security Migration Editor snap-in, it must be
initialized from the command prompt with the command:
regsvr32 sidwkr.dll
This initializes the class libraries used by the
snap-in.
To use the snap-in, add it to the MMC. Security Migration Editor
can also be started from the command prompt with the command:
sidwalk.msc
Further instructions on using snap-ins can be found in Help for
the MMC.
