By default windows phone opens up the mobile site (if available) of site you try to browse. Most of the sites will have an option to open the desktop site as a hyperlink in either top of the site or at the bottom. If it doesn’t then you change from the browser settings.
- In the IE browser, tap the ellipsis.
- Change the “Website preference” to “Desktop version”
- Browse again.
You can change the setting back at any time or leave it if you want desktop version by default.
