In IE, a stack overflow exception will occur around depth 250 however in WPAD it will occur on a depth of less than 150, ensuring a stack overflow exception/alert will be thrown in the exploit. There is a difference between the stack size between WPAD and Internet Explorer.

If you're still running Windows XP, it isn't secure to access the internet, no matter which browser you use - you must update your operating system. If you use Windows XP, the operating system itself is no longer supported by Microsoft. You will need to install an alternative web browser (see below) in order to access the internet safely using Windows Vista. Unfortunately, the latest version of Internet Explorer isn’t compatible with Windows Vista, which can’t go beyond version 9.

However, for the time being, the Edge browser is only available for Windows 10 users. Microsoft has released a new web browser, named Edge. If you run Windows 7, 8 or 10, you can update to the latest version of Internet Explorer, version 11. If you use Internet Explorer 8, 9 or 10, you must upgrade to a newer browser. These include vital updates to ensure the web browser is secure to use. Microsoft announced in January 2016 that it will no longer support versions 8, 9 or 10 of Internet Explorer with necessary updates.
