Fix new Win 7 SP1 system update high CPU and memory usage method

Recently reinstalled the Win7 SP1, the system update always fails and begins to suspect that there is a problem with the driver installation. However, the repeated installation of the old and new drivers will not solve the problem, the update Service CPU (Svchost.exe) high occupancy situation. Online also found a lot of ways, what restart services, repair Windows Update Services, such as a series of unreliable methods, are useless. Almost turned over the entire internet finally Kungfu, found the final solution, is the need to install a patch in advance, but after repeated experiments, it turns out that two patches need to be installed.

1, KB3102810 The patch can resolve the update CPU full load and large memory consumption situation

2, KB947821 is the Windows 7 System Update Preparation Tool, if only install the first step of the patch, and do not install this, then the system can be updated, but after a period of time, that is, after the installation of more than 100 patches, the same thing will return (tried n many lessons, the specific patch is not known.) At this point if the patch is not installed, the symptoms are installed in about 90% progress bar is not understood.

This is an issue with the new WIN7SP1 System update system, which may not be applicable if your system has been in use for some time after the problem occurs.
