Increase PC speed

Go to Power Options form. One method is via the Control Panel:

In the Power Options form, select Change plan settings item of the selected plan.

In the Edit Plan Settings form, select the Change advanced power settings item:

In the advanced power settings form, scroll down to the Processor power management section.

If the PC has the ability to dynamically change clock speed, there will be a Minimum processor state and a Maximum processor state. If the PC does not have the ability to dynamically change clock speed, there may be only the System cooling policy, or may even lack the Processor power management group.

Set the Minimum processor state to 100 (typically is 5). Insure the Maximum processor state is 100.
Note: Do not leave Minimum processor state at 100 on a laptop. It will more quickly run the battery down.
