windows update can't download

hi guys i can't download the latest patches for windows [i have a legit key]
i contact microsoft support and was advice to do this:
If you are running Ad-aware, ZoneAlarm, PC-Cillin, Norton Antivirus, Norton Internet Security, Norton Personal Firewall, McAfee, Proxomitron pop-up blocker, Ad Muncher, web accelerator e.g. "Slipstream", I would recommend you to temporarily disable or shut down any of these installed on your system
and try accessing Windows Update site. Be sure to enable them again when you complete the update process.

Step 1

The particular issue you are encountering indicates that the database where Windows stores the information on who is and is not trusted to install programs on your machine has become corrupted and unusable. To correct this:

Note: The Catroot2 folder is related with Windows Update and deleting or renaming this folder would not harm your system in anyway. When you next logon to Windows Update Site, this folder will be automatically recreated.

1. Close any windows you have open.
2. Click on Start, then My Computer
3. Open the C drive
4. If this is an upgrade over Windows 2000, open the WINNT folder. If not, open the WINDOWS folder.
5. Open the System32 folder
6. Find the CatRoot2 folder and right-click on it, and select RENAME. Change the name to CR2OLD. Make sure you hit Enter after typing in the new name, so the changes can be saved.
7. Close this window.

Now connect to http://windowsupdate.microsoft.com and check the status of the issue. I hope after the above steps you should be able to install the updates. If the issue continues, kindly proceed to next set of instructions.

Step 2

This error can occur if one or more of the following services are disabled or not running. We will therefore RESET Background Intelligent Transfer Service and the Automatic Updates service.

1. Click Start --> select Run. In the Run box, type services.msc Click OK
2. Find the Background Intelligent Transfer Service. Right-click on it and select Properties
3. Click on Stop and then again click on Start. In the Startup Type list, make sure that "Automatic" is selected. Click OK
4. Similarly find Automatic Updates service. Right-click on it and select Properties
5. Click on Stop and then again click on Start. In the Startup Type list, make sure that "Automatic" is selected. Click OK
6. Close the Services window

[Please note that if the service is already started the "Start" button will be grayed out. In this case "Stop" the service and then "Start" it again. On the other hand if the service is not running, the "Stop" button will be grayed out. In this case "Start" the service]

Step 3

We also need to register the ActiveX control files needed to access the Windows Update Site. We need to do this since the error can occur if these files are unregistered on your system. To do this you can try the instructions provided below:

Note: There is a Single Space between the regsvr32 command and the file name JSCRIPT.DLL . The same goes with all the commands provided below.

1. Click on Start, point to "Run"
2. Type in "regsvr32 JSCRIPT.DLL" (without double quotes) and click Ok.
3. Type in "regsvr32 MSXML3.DLL" (without double quotes) and click Ok./
4. Type in "regsvr32 ATL.DLL" (without double quotes) and click Ok.
5. Type in "regsvr32 WUAPI.DLL" (without double quotes) and click Ok.
6. Type in "regsvr32 WUAUENG.DLL" (without double quotes) and click Ok.
7. Type in "regsvr32 WUAUENG1.DLL" (without double quotes) and click Ok.
8. Type in "regsvr32 WUCLTUI.DLL" (without double quotes) and click Ok.
9. Type in "regsvr32 WUPS.DLL" (without double quotes) and click Ok.
10. Type in "regsvr32 WUWEB.DLL" (without double quotes) and click Ok.
