In XP, the equivalent key is:

"HKCU\Software\Microsoft\Windows\ShellNoRoam\BagMR U"

When I say template, I'm refering to the choices that appear on the
'Customize' tab: 'All Items', 'Documents', etc. These govern the tasks
offered, default icon style, & default columns selected, etc. Nothing so
advanced as retaining HTML malware

They're suppressed by default in XP, but could be activated:

http://support.microsoft.com/kb/819028/

I doubt they work at all in Vista, but I never really played with them, even
in XP.

There was under XP, but it was disabled by default in one of the updates,
but can reactived via a policy setting. Haven't checked under Vista -- I
assume it's at least disabled by default if not completely unavailable.

Only items under 'HKCU\Software\Classes' & 'HKLM\SOFTWARE\Classes' merge to
form the HKCR key. User-specific takes precedence over machine-wide, but
'Defaults' uses a Binary data structure to hold the view settings and holds
more specific detail, such as column width, whereas 'FolderTypes' uses
individual values for Icon Style, default columns, etc -- there're not
identical keys/values like:

'HKLM\...\Explorer\HideDesktopIcons'
&
'HKCU\...\Explorer\HideDesktopIcons'

All folders are using some sort of template. 'All Items' is the most
generic, so set an 'All Items' folder to the view you want to be your
'default' view & use the 'Apply to Folders' option. Even with the
'AllFolders' reg key in place, you still have the option to customize your
Pictures folder back to the 'Pics & Vid' template, and can use the 'Apply
this template to all subfolders option' as well.

Well, I think that settles my problem then. I'm still testing. Will report
back later.

Thank you for all the help Keith.

Well Keith, it seems that with your registry modification (disable content
sniffing) and the use of templates I could make Windows Vista behave the way
I expected. Finally! Now new folders are created with the view I wanted and
it seems Windows is not losing customizations on my "different" folders (that
used to bother me as well). Probably because it is not saving any different
customizations in registry anymore.

Just one more question. Keith, if I wanted to restore Windows Explorer
customizations back to Windows post installation default (that is, no
modifications at all) can I simply delete the entries on
HKCU\Software\Classes\Local Settings\Software\Microsoft\Windows\Shell\Bags
and BagMRU?

Thank you for all the help. I do appreciate it.

Glad to here it's all sorted.

To restore to default state, you would need to delete the two keys you
mentioned as well as this key:

"HKCU\Software\Microsoft\Windows\CurrentVersion\Ex plorer\Streams\Defaults"

and the value named 'Settings' under:

"HKCU\Software\Microsoft\Windows\CurrentVersion\Ex plorer\Streams"

OK then, I might try deleting them one day. For now Windows is doing great.
And don't feel embarassed, everybody makes mistakes.

Thank you again.

That's good. WinME let you slam the door on "View As Web Page", but
XP and Vista no longer have such an option, and yet have suspiciously
detailed and lavish possible views. It wasn't at all clear wether
this was using Folder.htt etc. but with no safety catch anymore.

OK, good that they're suppressd by default.

OK, that's good.
