Windows validation might not run properly if your web browser is not configured to allow active scripting. To allow active scripting so that validation can run properly, do the following:
Open Internet Explorer.
Click the Tools menu, and then click Internet Options.
On the Security tab, click the Custom level button.
Scroll down the Security Settings list until you see Scripting and Active scripting.
Click Enable, click OK, and then click OK again.
After you have completed these steps, retry Windows validation to run the test again.
