Now the size of registry (size of the Config folder) is 929 KB.
First I used the portable version of the jv16 PowerTools to clean and compact the registry. Then I cleaned the registry manually using regedit.exe. After all I exported default, sam, security, software and system from registry saved them as hives on my NAS through network. Then I replaced the files default,sam,security,software and system in Config folder by saved hives (under the same names).
To describe the registry removings is difficult because they are very numerous.
Here are some screenshots which help to fathom that it is possible to remove.

Wow this is really an accomplishment that you have reached....bravo. So tell us how it sounds. Apparently there is a bright light in Moscow.
Theo, for a long time already the sound in my system is great therefore it is difficult to tell about any appreciable changes as I do much tweaks recently without having time to trace changes carefully.
In this case I probably take the more interest in how much possible to reduce a system size.

Hi, Serge!
1. Did you delete all the branches inside the selected branch, lika ALL HKEY CLASSES ROOT or you show only what remains?
2. Having an extremely small registry size is NOT ITSELF AN OBJECTIVE. Matter is, however small, the registry eats 4mb in paged memory pool. There is a feature like RSL (registry size limit), if RSL or the actual size of the registry is less than 4mb its size is ignored and by default 4mb will be allocated anyway. Now the deletions of entries that invoke unnecessary threads is MORE IMPORTANT, and here I congratulate you.
3. Serge, you seem to be much more apt at computer than me. Please, try to find these two things: assigning memory (in mb) to an application - in our case it is cmp-cplay and MOST IMPORTANT - how to set the size of pages, that awe locks from 4kb to ! 4mb. It IS POSSIBLE in xp, but the info is somehow hushed or vague.
With all my respect, Serge.

http://blogs.technet.com/b/askperf/archive/2007/03/07/memory-management-understanding-pool-resources.aspx'The physical pages that can be allocated for an AWE region are limited by the number of physical pages present in the machine, since this memory is never paged'
It appears then, that we (assuming 1x512MB ram) want to maximize the non-paged Memory (which would be regvalue 'NonPagedPoolSize' in bytes) ?
Steppe of course has the idea (sounds promising) to make the AWE memory pages larger (http://www.audioasylum.com/forums/pcaudio/messages/9/99374.html), I'll also try to search for info on this ;)
First link says at last, 'AWE provides page size granularity appropriate to the processor (for example, 4 KB on x86), which is more useful to applications than large pages (for example, 2MB or 4MB on x86).'
So we might try to search from another perspective, that is making Windows believe its using some other 'CPU type' (...) if possible at all, to make it use larger pages. Thinking of, a lesser interval that the ram is accessed would lead to less mobo/psu-disturbances (which leads to ...cMP users know ;)
Or second possibility, Coder Cics joins back in and may shed even more light on the mermaids (already shimmering in 24bit colours I think) tail ;)

It's daylight in India as well :) but Ur tweak has clouded the light... Let the details rain out of Ur tweak so that it gets brighter again...
