Creating a Restore Point in Windows Vista May Result in Prolonged High CPU Utilization

View products that this article applies to.

Symptoms

Consider the following scenario:

  • You have a computer that is running Windows Vista.
  • Windows has been installed on a hard disk partition that is 2 Terabytes or larger.
  • You manually create a Restore Point or perform another action such as install a service pack, new application or an update from Windows Update which may create a Restore Point.
In this scenario, you may notice the CPU utilization will become very high and the system seems to be hung and unresponsive. If you try to open “My Computer” during this time, you may not see any disk drives listed in the opened window. It can take five minutes or longer before the system returns to normal CPU utilization.
