  • Hi,

    Could you please share us the error message when you tried to open the registry item you want?

    Also I think we can try to collect a process monitor to track the whole process when you performed the actions.
    The following is the steps for your reference:
    1) Download Process Monitor:
    http://www.microsoft.com/technet/sysinternals/ProcessesAndThreads/processmonitor.mspx
    2) Extract it, double-click the Procmon.exe file to start Process Monitor.
    3) While Process Monitor is running, try to perform the whole steps again.
    4) When the issue has been reproduced, please switch to the Process Monitor window, and then click the microscope icon in the toolbar to stop the capture (CTRL+E).
    8) On the File menu, click Save. Save the Process Monitor log to any folder that you want.

    For this kind of issue, we can filter the path to the path you are trying to access and check if you can find any clues.

    Also if you want us to check it for you, please upload the log to your skydrive and share the link, I will try to check it. At the same time, provide the path you are trying to access.

    Thanks.

  • Hi,

    First be sure you run RegEdit as Administrator

    Right click the key in the left hand pane ... select permissions from the context menu

    In the permissions dialog, click the advanced button.

    In the advanced security settings dialog switch to the Owner tab

    I assume your usercode is a member of the local Administrators group

    Click the Replace owner on subcontainers and objects box.

    If Administrators is NOT the owner, select it in the change owner to box...press Apply...OK.

    You are now back at the Permissions dialog box.

    Select Administrators and give them Full control by selecting the Full Control checkbox in the Allow column...press Apply ... Ok

    Regards,

    Leo   Huang

  • OK.

    Detail steps:

    1 Run Regedit with administrator

    1. Click Start and input “Regedit” in Search Box
    2. Right Click “Regedit” and select “Run as administartor”

    2 Go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Class\??????????\Properties, you will see the error message that access denied to open that key

    3 Right-click the key, click Permissions, click advanced, click owner, click other users or groups, click advanced, click find now, select your account, click ok, click ok, select your account, click ok

    4 Now you can set permissions as you wish. do this for every key you want.

    Regards,
