Solved
In my case user whose registry file I
want to update (target user) is not logged in, therefore
..the user’s registry file is not
loaded, therefore
…the registry path\key I’m pointing to
is incorrect
My solution in a nutshell:
1. Verify
if the correct user id logged in (I could be lucky)
2. Get
the AccountID of current user logged in
WindowsIdentity WId = WindowsIdentity.GetCurrent();
WidAccountID = WId.User.ToString();
3. Get
the AccountID of the target user using NTAccount, SecurityIdentifier (see previous post)
NTAccount NtAcct = new NTAccount(definedUserName);
SecurityIdentifier SecId = SecurityIdentifier)NtAcct.Translate(typeof(SecurityIdentifier));
SecAccountID = SecId.ToString();
4. Compare
the WidAccountID = SecAccountID
5. If
they are not equal, use RegLoadKey to
load the target user’s registry hive file
6. For
above step, remember to prefix the registry sub key with registry hive alias
7. If
I’m lucky and target user is logged in, prefix registry sub key with AccountID
8. Update
the registry file
9. Always
close the registry key
10. And
if registry hive file was loaded, use RegUnLoadKey
to unload
NOTE: I had a case where
target user is not logged in but the hive file is loaded in registry, so my 3
checks are as follows:
1.
Target
user logged in (WidAccountID = SecAccountID).
-
Set SecAccountID as
registry path prefix.
2.
Target
user not logged in but hive file loaded in registry.
-
Set
SecAccountID as registry path prefix.
3.
Target
user not logged in, hive file not loaded in registry.
-
Load
hive file and set hive alias as registry path prefix
