  • Control Panel; Does not open programs and features.

    Help! Programs and features in Control Panel does not open. It's as if the file is no longer there.

    Hello

    I had the same problem, caused by an update of thugs. I had to do a repair installation to fix the problem. For this,.

    1. Start your Windows computer.
    2. Insert your Windows system DVD into the DVD drive.
    3. Once there either using Windows Explorer or AutoPlay navigate Windows system disc and double-click on the file called "Setup.exe".
    4. Let Windows boot phase review and collection, when that is complete, Windows continues to install Windows 7 on your existing installation of Windows 7. If there is a problem, Windows will give you the opportunity to continue or back out (I would recommend back out).
    5. Once installation is complete, you will need to then activation key, then go to Windows Update and precede to download and install all the WU you miss.

    That's all. It takes more time to make that a full install as Windows must work around your installed files. But it is the method that worked for me.

    Let me know if this solves the problem for you.

    When I click on the start menu control Panel icon, it says and I quote": {26EE0668-A00A-44D7-9371-BEB064C98683}"the RPC server is unavailable." All other icons are thus working computer, network, printers, etc all its only the control panel is not working. Two questions how to fix this and what is the RPC server?

    Hi I.Saenz,

    1. did you of recent changes on the computer?

    2 when was the last time it was working fine?

    3. do you have security software installed on the computer?

    Remote procedure call (RPC) is a part of Windows programs, which is "an interprocess communication technique that allows the software client and server to communicate." CPP is designed to provide a common interface between applications, making it easy for programs to communicate with the servers.

    Check if the problem persists in safe mode.

    Start your computer in safe mode

    http://Windows.Microsoft.com/en-us/Windows-Vista/start-your-computer-in-safe-mode

    Restart the computer to return to normal mode

    If the problem persists in safe mode then I suggest that scan you SFC on the computer that would be a system file corrupt on the computer search and replace.

    The analysis may take some time, so be patient. Windows allows to fix corrupt or missing files it finds. If the information of the installation CD is required to fix the problem, you may be asked to insert your Windows Vista installation CD.

  • Some features in the Control Panel does not start

    Original title: some feauters on Control Panel do not open

    my computer laptop OS is windows 8

    When I open my control panel functions are not open

    options, troubleshooting, customization of power

    Pleas give me a few tips, how can I do to fix

    Hello Kiran,

    Welcome to the Microsoft Community Forum.

    According to the description, I understand that some features don't not throw in Control Panel. I'll be happy to help you with your query. However, let me ask you a few questions to better understand the issue and assist you accordingly.

    1. What happens when you try to start the service, as said above?
    2. You receive an error message? If Yes, what is the exact and complete error message?
    3. You did any hardware/software specific change in the computer before the show?
    4. You use any third-party antivirus installed on your computer program?

    The issue may have been caused due to conflicts between third-party software. Try these steps and see if they help.

    Step 1: Start in safe mode

    With the parameters of Windows startup screen (formerly advanced startup options), you can start Windows in different advanced troubleshooting modes, so you can find and fix problems on your PC. In previous versions of Windows, you might get to the screen by pressing F8 before Windows starts. Windows 8 PCs starts quickly, so there is no enough time to press F8.

    See the article: Start settings for Windows (including safe mode)

    Step 2: Perform the clean boot

    Put your system to the clean boot state helps determine if third-party applications or startup items are causing the problem. You must follow the steps in the article mentioned below to perform a clean boot.

    See the link to perform the clean boot.

    How to perform a clean boot in Windows

    N OTE: see 'How do I reset the computer to start normally after a boot minimum troubleshooting' to reset the computer starts normally after troubleshooting.

    From now on, try the steps above and check that if these functions of launch and let us know the result so that the answers to the questions, we will be happy to help you further.

    Thank you.
