As a full member now, you should know that we expect your code to be posted in [code] tags (See How to Ask a Question).

This makes it easier for our Experts to read and understand it. Failing to do so creates extra work for the moderators, thus wasting resources, otherwise available to answer the members' questions.

Please use the tags in future.

Nice try with the code tags. Unfortunately, you used <code> instead of [code]. The code tags are enclosed using square brackets.
Hai friends it is not working in any browser , pl check and tell me.....sorry for inconvenience.
What errors do you see? Check the error console.

As I said, this is old code. If you've not written this, I would suggest finding a newer version that works in modern browsers.

The easy way to turn off automatic updates for Windows 10/11

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not.
