I would know what limitations do we have to follow to be sure our application is compatible under a Guest and Limited account on XP as well as Vista.
for example, can we write settings to HKEY_LOCAL_MACHINE/Software ?
do we have right to install something in windows directory? what are the limitation? I think it's ok to drop a file to temporary folder,
if for example I want to show a message or something the first time my application run on a computer, if I can't write to HKEY_LOCAL_MACHINE, means I have to write to local user, but then, it will be shown 4 times if there is 4 users who open it on their own session,
so where to write settings to be able to use them from any account and write to it too from any account.
so, what I have to follow to be sure my program will be 100% functional/compatible under limited/guess account (and this on XP as well as Vista),
Note that I don't want asking permission or asking elevation to user.
500 points for this one
thx a lot in advance
