I don't know whether inmates can see this when you load the Security hive. There is a copy of Sam inside the Security hive. The 2 Sams make changes simultaneously, if data in Sam hive is changed.
I can't see the Sam inside Security either, when using load hive and log on to system account. In order to see all data and make changes simultaneously, one need to log on to the system account in the CMP Windows.
Delete the data inside Sam hive and the deletion will be reflected in the Sam inside Security hive. You'll hopefully get a 8kb Security hive.

The Sam hive remains the same as per my last report - "Please see Screen Shot". Please don't touch anything inside Account and Builtin. There is nothing inside RXACT but the folder is needed.
I've deleted more from the Security hive, as follow:
1. The remains of Security hive as per the screenshot. The presence of Account\SID\Priviledges does not improve sound;
2. Delete the Key/Dword inside PolAdtEv, PolAdtLg and PolMod respecticvely. The folders are needed; and
3. In RXACT, delete content of the log only.
Please don't touch PolAcDmS, where the machine SID and backup of Sam reside, and SecDesc.
There are some good improvements after the registry deleletion. Music is definitely more 3-Dimensional; there are slight but noticeable improvement in minor details. Less policies in the hive perhaps reduces interactions between the Security hive and Isass.exe, hence, less noise and overhead.
The deletion is done on XP Home SP1.
The secret was in leaving all the other policies in (as per steppe) then I was ok.
Hello! Ted, I have just restored my cmp. I have tried new shell + shlwapi and even + Jack's gdi32.dll, still no sport. Jack! If You read this, where is this shell from, really, just for interest?
Serge.
I believe they(shell32 and shlwapi) are from xp sp1 home and they did not work in my system either. My thought is that, like your set of files, they probably will all have to be substituted for it to work. Jack indicated that his file set is from a whole bunch of different sources.
Mr. Wong is using this instead of NTFS.
Since I assume we have deleted the FAT files and entries in the REGISTRY this can cause a problem.
I am making a new install with FAT on all drives and see if I have success.
You are spot on check your email.
I replicated your security hive screen above and got a bsod. Upon looking at my hive before I did your edits I noticed that I had a few more entries under Policy in parallel with PolAdtEv, PolAdtLg and PolMod that I deleted. So I am going to try again leaving in those other entries. I am on another computer away from my cmp box so I cant copy them here but there are 3 or 4 of these.

from one direction, bottom up or reversed. Jump to next if unsuccessful. Keep the Account\SID for the time being, that's the last one to be deleted.
After emptying some of the key/string, try deleting the folders.
If you have no success deleting a string/dword, try emptying it's content.
You said: '...The presence of Account\SID\Priviledges does not improve sound...' I just listened and you are right no difference maybe even a slight degredation.
Its interesting that I have no sam within security. I do have a sam within sam but that is all, There are differences as well.
Going to try your new registry edits now.
As always thanks Jack.
The Sam in the Security hive(not in Sam) can only be seen when one boot into its own Windows and view directly in Regedit. It's not about loading the Security hive using another computer, the "Sam in the Security hive" can't be seen this way.
Here is how I did it using Snapshot.
I opened an earlier image of my os.
I pulled my Security file out of it and placed on my desktop.
I used the new program Jack mentioned to open and hack it.
I used Ntregopt to compact it (while still in regedit mode)
I rebooted.
Loaded my ssd into my docking station on my desktop.
Replaced the Security file with the newly hacked/compacted Security file.
Rebooted and now I am listening to see (hear) if I can notice a difference.
For those of us who can no longer do ANYTHING on our cMP installs?
Do we load an "older" version and work on it there, save it, and place it in out minimized installs?
For me, I would use the first ghost image or without it install a new Windows using the same Nlite disc. On 1st boot, I'll log on to system account and do Sam & Security slimming simultaneously. Thereafter, copy the Sam and Security to the config folder of the slimmed CMP Windows.
I am lost with all the changes to Sam and Security changes (which ones to do).
@jackwong96: can you tell me (maybe via a link to the changes) exactly which changes you make in Sam and Security after a fresh install so that I can try them?
This is how it looks, so far, after booting into Windows.
Actually,I found that load hive & delete data in SAM only, will result in corresponding changes mirrored in the SECURITY when boot into Windows.
For SAM, it is 8kb.
The Security hive is also 8kb. I have not yet decide which Policy\Account to keep. S-1-1-0 is "Everyone" and S-1-5-32-544 is "Administrators". The Privilege etc are still inside. I have copied the Privileges granted to "Administrators" to "Everyone" in case they are needed.
The PolRevision & PolSecret... were deleted and no longer present when I load hive. Nevertheless, they kept coming back in Windows(only) despite further deletions.
One thing, add read and write rights for Everyone and delete System and anyone else in all keys and sub-keys after load hive. Right click "Permission" to do that.
