Windows 7 Edition home premium with service pack 1: I need to get drivers for DC bus SM Bus Contrller and universal.

I have trouble finding drivers for SM bus controller and bus universal controller.  I don't know why they are not loaded on the hard drive or if they were at the same time, how or why they are missing today and, more importantly, where do I go to find these drivers?  Your help is very appreciated!

  • Problems of displacement, deletion, renaming of files in Vista Home premium with Service Pack 2

    Since SP2 was installed I had travel problems, copy, delete and rename files.  When I do all this the appropriate box opens, but it will remain open and the computer will not respond.  The only way to solve the problem is to use the Task Manager to end the task.

    I'm running a processor 2.33 GHZ of intel with 23 GB of ram and a 500 GB with 310 GB of free disc.

    Free unlimited installation and compatibility support is available for Windows Vista, but only for Service Pack 2 (SP2). This support for SP2 is valid until August 30, 2010.

  • OK, I have a legal copy of vista Home premium with service packs and updates from microsoft and want to start clean with a clean installation I do not have the original, only recovery and put installation disc at level Express disc?

    OK, I know that this may be simple for most, but I have an of a moment _ this find.  As I said legal copy that has been saved... I backed up all my files on DVD, I don't care if I lose all the programs that I can always download them later.  Basically I want is that it was when I brought home the first time.  I searched high and low for the original disc of Vista but no luck.  I do not have people upgrade at any time, but I was not able to find a definitive answer about it online.  Not too complicate it again but I have 4 GB of ram and processor can run 64-bit, and I have 32-bit curently I'm sure you know where I'm going with that.  I know a little about how to do it, but want reasurance and direction from someone who knows hit safe and ready to help.  Any person who get end to this nightmare for me will be really appreciated.


    Contact the manufacturer to obtain a set of recovery discs original (for a fee) and use them to make the initial installation.  Activate it.  Then you can do the upgrade and activate that.  You must install the original operating system in order to install the upgrade.  If you are going from 32 bits to 64 bits that cannot be done with an upgrade - which requires complete and clean installation.

    Here is the Microsoft policy on replacement software;

    I hope this helps.

    Thank you for your time and effort to get back to us, and I apologize for the delay in responding.

    Method 1 step number d makes reference to the present Details tab on the event viewer, where you can get the details of the error. First, search for the error which will be something like Windows cannot process extension Client Strategy Group-side and click on the error and then click the Details tab and make a note of the GUID (Globally Unique Identifier) for the extension defective client-side. For reference, see the screenshot:

    Now come to step f number , it indicates the location of the Group Policy Extensions so that you can check if the extensions shown in the case log and the Registry Editor extension have a difference. The path of the GPExtension is HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion\Winlogon\GPExtensions. For reference, see the screenshot:

  • I have Windows XP Media Center Edition Version 2002 with Service Pack 3 and I tried to run Media Center but I get an error message with ehshell.exe.

    original title: error with ehshell.exe

    I have Windows XP Media Center Edition Version 2002 with Service Pack 3 and I tried to run Media Center but I get an error message with ehshell.exe. Could you help me?

    This problem exists since the 1st Media Center. SP2 and SP3 had a difficulty, but it is obvious that it doesn't always. The same problem still exists in Vista today with a lot of other carried over from XP. System restore would work, but you do not have any good restore points so reinstall an operating system seems to be your only option.

    You probably don't want to do an OS reinstall you need for Media Center, but since it does not at all, you might want to play then remove the Media Center updates and or SP3 and reinstall them.

    You're confused system recovery and system restore.

    System Restore makes the settings from your computer to an earlier date; It will not reinstall the operating system.

    System recovery reinstalls the operating system how much you bought your machine; as for the new State.
