This one is probably for a MVP, MSFT or anyone else familiar with
Win2K's desktop heap.

I'm getting "out of memory" errors while doing certain functions in
Adobe Photoshop 7.01 (specifically, working with 1-bit/B&W
graphics), although I have plenty of free RAM and pagefile remaining.
So I suspect a leak exists in PS. I'd like to allocate more heap to see
if it will work around the issue.

When poking through the registry I discovered the SharedSection
of this key...:

HKLM\System\CurrentControlSet\Control\Session Manager\
SubSystems\Windows

....has four parameters: 1024,3072,512,512

I was able to locate the purpose of the first three parameters in
MS's tech database:
http://support.microsoft.com/default.aspx?scid=kb;EN-US;184802
http://support.microsoft.com/default.aspx?scid=kb;en-us;126962
but I can't find any notes related to the 4th parameter. Does anyone
know its purpose?

Also, I've read that removing the Optional, Os2 & Posix keys in
Session Manager\SubSystems will free up memory/resources
(I'm not using any of them). Is this correct?

Thanks,
Rick
 
I'm pretty sure deleting those keys will free up pool and heap. It wil
also make your machine more secure. Supposedly, the fourth value i
