    Apparent bug in SysInternals Contig v1.8


    I can't find a SysInternals forum online. If this is not the right place to post this, please direct me elsewhere.


    There is an apparent bug in Contig v1.8. In some cases, "contig -s -v <filespec>" will not use the last block of free space on a volume. In other cases, it will. I've seen both behaviors on the same machine, but I can't explain when it happens and when it doesn't. I've been unable to defrag a file even though there is a huge amount of free space at the end of the volume.


    In this case, there was no other I/O in process to the volume (not the system volume) that could explain another task reserving the extent.


    Case 1 - "contig -s -v" does not use the last block of free space on the volume. Volume is FAT-32.

    In this case, the free space extent at the end of the volume was used when defragmenting.


    So the behavior appears to be inconsistent. Note that, in both cases, the largest extent of free space was at the end of the volume.

    How to Remove Sysinternals Live?


    I mistakenly downloaded and installed Sysinternals Live instead of only Autoruns.

    I've looked through my list of installed programs but I don't see SysInternals Live.

    Can anyone suggest a method by which I can remove SystInternals Live from my PC?

    Thank you.
