Windows Updates Failed

I noticed that since 4/28 all my windows updates have been failing. I have my updates set to auto to download and install the updates.

I manually downloaded and installed each one that failed and all is fine now but my question is why are they failing when they are set to auto?

Also is there a updates site where I can go and see what is available and select them to manually download and install? This time I had to google each one that failed to find the download page for Microsoft.

Thanks

Microsoft has released a new tool named System Update Readiness Tool to resolve certain conditions that could cause installing updates and other software no to work in Windows 7, Vista and Server 2008 systems.

Maybe that will sort your problem.
