Access to local machine in windows 7

Question

I want to create a registry key in local machine hive in windows 7. I used the following code in order to do so:

    RegistryKey regKey = Registry.LocalMachine.CreateSubKey(@"Software\Test", RegistryKeyPermissionCheck.ReadWriteSubTree);

the code runs fine without any error. but when I looked at my registy using regedit.exe I don't see the key that i've just created. can anyone help me please.

regards

Answer 1

In all likelihood your application is running without a manifest and is writing to the virtualized copy of HKLM. To test my theory, right click your exe and choose Run As Administrator. If it then writes to the correct area, this is what is happening.

If this is the issue, either change your mind about writing to HKLM (users don't like UAC prompts) or put a manifest on the exe that has requireAdministrator so that it will always request elevation and work properly.

Answer 2

What is the length of your key name? There is a known bug in regedit that wont let you see keys with names longer than 256 characters.
