Hi Jeremy,
There's a fairly simple rule controlling which string type should be used. If
you want a variable to be parsed (replaced with variable value) you have to use
reg_expand_sz, if you just want to store a value with %signs around it, reg_sz
is fine.

Hi Joe,
If REG_SZ works without giving you problems, then it should be okay for
you. However, I always use REG_EXPAND_SZ simply because Microsoft say you
should. With REG_EXPAND_SZ string values, you can safely use environment
variables for paths that are stored in the registry. This ensures that the
any environment variable used is correctly expanded. Leaving it as a REG_SZ
value can provide inconsistent results depending on how well the
application accessing the keys has been written.
As a note you shouldn't be directly modifying the anything under the "Shell
Folders" key, just the "User Shell Folders" key.
And whilst you can change the REG type, you can delete the REG_SZ and
recreate it as a REG_EXPAND_SZ.
Whilst that's not a difinitive answer, it may give you a guide.
Kind regards,

[THIN] Explorer shell folders in

Please respond to

Hi all,
I've researched this one briefly, using google, tweaking keywords, and
limiting search results by domain. (e.g. using site:microsoft.com)
Viewing the contents of the registry, the default key value is always
REG_SZ, and can't be changed.
On Windows 2003 Server, because the default value is REG_SZ, can you modify
a default value to include an environment variable?
E.g Replacing "c:\documents and settings\administrator\recent" with
"%userprofile%\recent"
I have found Microsoft Knowledge Base articles which do state that to use
environment variables, you have to use the REG_EXPAND_SZ value type.
However I can't find a definitive answer to my question before I run any
tests.
Thanks!
Joe
