What to do if my Windows computer starts slow

A slow or long Microsoft Windows startup (boot up) can be caused by many different issues. This page contains various suggestions and tips to help improve the overall speed of your desktop or laptop computer's startup or reboot.

Disable startup programs

Programs that are loaded as the computer starts up remain active in memory. Consequently, they are one of the main causes of a slow boot into Windows. Disabling programs you don't often use from automatically loading up each time the computer powers on can decrease boot time.

ScanDisk and Defrag

Using Microsoft ScanDisk and Defrag or similar disk utilities help verify your hard drive is running free of errors while organizing stored data in the most efficient manner possible. We suggest running both of these utilities at least once every few months.

Insufficient hard drive space

For your computer to run optimally, it needs at least 250 MB of available hard drive space. If you have less than this amount, slowness in both general performance and the boot time can occur.


Update drivers and Windows

Corrupt, incorrect, or out-of-date drivers can cause many different issues. Make sure your computer has the latest drivers and any available Microsoft Windows updates.


Registry cleaner

Although we do not often recommend registry cleaners, in some rare situations, they help improve the overall performance of Windows, including startup. If you ran through all the recommendations above with minimal startup speed improvement, you may want to clean your system registry.
