How to Improve the Performance of Silverlight

Updated April 12, 2017

Silverlight is a program that interacts with websites. Video streaming, managing dynamic Web pages and running media on your cell phone are three common reasons that devices come preloaded with it. When you want to watch a movie online, you need two things: a stable, secure environment and a flexible platform. Unfortunately, software conflicts or hardware problems sometimes cause Silverlight to malfunction. Troubleshooting Silverlight usually solves the problems.

From your desktop, click "Start," then "Control Panel," and double-click "Programs and Features." Search for the Silverlight program in the list. Right-click the program, then choose "Repair." Click "OK." Visit the Microsoft Silverlight website and reload Silverlight if Windows Installer shows you an error message. It might start with "The feature you are trying to use..." Reboot the computer.

Open your Control Panel by clicking "Start," then "Control Panel." Double-click on the icon that reads "Windows Update." Choose "View your update history," then scroll through the list. Look for any line with the name Silverlight in it --- see if the Status column reads "Successful" or "Failed." Hit the "Back" arrow, then choose "Check for Updates," then wait a moment. Perform updates as prompted --- click the "Install Updates" button. Restart the computer.

Click "Start" to bring up the Search box. Type "chkdsk" (without the quotation marks) in the box and press "Enter." Look for an icon at the top of the menu that appears --- the word "Programs" will appear just above it. Right-click the icon. Click "Run as Administrator," then choose "Continue" when prompted. Wait a moment for a new window to appear. Allow the computer to run its course afterward. Restart the computer. Choose "Error Check" if this does not improve performance of Silverlight.

Right-click "Start," then "Open." Search for the phrase "Local Disk (C:)." Right-click on that line, then click "Properties." Click the "Tools" tab. Click the "Check Now" button, then the "Continue" button. Place ticks at the boxes next to every sentence that appears, then click the "Start" button just underneath those boxes. Wait for a prompt to appear --- it will most likely read that you have to schedule a task of some kind. Follow the prompts to schedule the task, then click "OK," and close out of all your windows. Restart your computer.

Use the Device Manager. Click "Start," then "All Programs," and then "Accessories." Press "System Tools," then "Control Panel." Double-click the icon that reads "System." Click "Device Manager," then choose "Continue." Scroll through the list that appears. Look for any exclamation or yellow question marks. Right-click, then "Scan for Hardware Changes."


Download a new version of Silverlight at Microsoft's Silverlight website. It may help you to improve the performance of Silverlight.
