Some users have experienced problems using the latest iteration of Microsoft's Web browser, but removing IE10 isn't as straightforward as installing it. See all Windows tutorials.
If you look in the section marked “Turn Windows features on or off", you will find it listed there, but unchecking it simply turns the browser off entirely, leaving you with no working version of Internet Explorer. Take a look at How to upgrade to Windows 8.1 UK too.
If you want to “roll back" to IE9, you'll have to take alternative steps. Thankfully, this process is relatively easy:
Internet Explorer 10 is installed as an update rather than as a program or a feature. To remove this update, go to the Start menu and start typing “programs and features" into the search box.
Programs and Features should appear in the search results. Click on this option to be taken to the relevant section of the Windows control panel.
From here, click on “View installed updates". Windows Internet Explorer 10 should appear as one of the installed updates – you may need to scroll to find it, depending on what other updates you have installed.
Right click on “Windows Internet Explorer 10" and select “Uninstall". This will start the uninstallation process and prompt you to restart your computer.
When you restart, you will have reverted to Internet Explorer 9.
If you're comfortable using the Windows command line, you can achieve the same effect by opening up an Administrative command prompt and typing the following command:
“wusa /uninstall /kb:2718695 /quiet /forcerestart"
This will run the same procedure silently in the background and then restart the PC automatically. If you don't want the PC to restart, you can use “/norestart" instead.
