Mind you, there is a difference between the "special folders" (=symbolic
path names) :
AppDataFolder
= Full path to the Roaming folder for the current user
and
CommonAppDataFolder
= Full path to application data for all users.
and
LocalAppDataFolder
= Full path to the folder that contains local
(nonroaming) applications.
To my understanding, CommonAppDataFolder is virtualized to
\Users\%USER%\AppData\Local\VirtualStore\ProgramData\ ,
which is at least a form of protection. Also, normal users would not be
able to delete files from CommonAppDataFolder , which is another form of
protection.
I haven't hacked Windows for a long time, but my guess is:
1) you are running as administrator,
2) or you (partially) disabled protection.
Which is not the best way to test applications.
Only your installer / uninstaller should touch CommonAppDataFolder .
I suppose the merits and best practices of folder virtualization are
documented on MSDN somewhere.
You are certainly not the first one to bump into this, a popular search
engine gives me 909000 hits on q=windows7+programdata, for example
