I have windows 7 ultimate 64bit and I am having a few problems. I cannot update it shows that their are updates but when i click on it it does nothing. Action center won't work so I uninstalled Microsoft security essentials and installed Avast and Super anti spyware. I tried the fix it but it says it had a error but did not say what kind of error. Any help would be appreciated.

Here are some notes that may help resolve problems encountered when installing Windows Updates. The process of installing updates comprises downloading, installing and configuring the operating system to use the new updates. Some updates require the computer to be restarted and when this occurs configuring occurs as the system is shut down and is completed when the computer is restarted. It is important not to interrupt the configuration process as configuration involves making changes to the registry. If interrupted, the result can be a computer that will not boot. A lot of problems arise from setting Windows Update to automatically update. You may prefer to change this setting. Select Start, All Programs, Windows Update, Change Settings. Under Important Updates is a box showing the current setting. Click on the Arrow down to the right and change the selection to Check for Updates but let me choose whether to download and install them and click on OK. If you encounter problems updating or you are not using the Automatic Update you should manually update by selecting Start, All Programs, Windows Update, Check for Updates. Check the boxes before the updates you want to install, click on Install and click again on Install in the next window and the process of installing starts. You should let the process proceed without interruption. Multi-tasking at the time updating is in progress is unwise. The progress window will tell you what is going on. You need to be patient. If you have a number of updates to install break the task of updating into two or more tasks. If you have been having problems with Windows Update run Disk CleanUp (or better still cCleaner) and Disk Defragmenter ( or better still Defraggler) before installing any large download. If the measures above fail to resolve your problem select Start, All Programs, Windows Update, View Update History and post the Failure Code and Update reference number to the Windows Update Forum at Microsoft Answers.

Try running "fixit" utility from Microsoft http://support.microsoft.com/mats/windows_update/en-us if that doesn't work for you then you need to find WindowsUpdate.log and check in the log why things are not getting installed. event viewer under system will also give you some clues why updates are failed
