Many early testers of Windows 10 have been complaining that Internet Explorer is rather slow for them, as a couple of forum posts have surfaced at the time of release.

Windows 10 users have used the Feedback app in Windows 10 TP build 9860 to complain about the existing Internet Explorer version. Here’s what one of them has been saying:

“Can’t say why. Page loading super slow. Even already visited pages opened in new tab”

Some have been saying that the Internet Explorer 11 browser also crashes all of a sudden, does not show all letters after an update, does not display web pages correctly, and performance with JavaScript is really slow.

How to speed up your Internet Explorer

Clear IE Cache regularly

The first thing you can do is to clear Internet Explorer Cache. You can do that from browser‘s Settings following the steps below, or with some third-party cleaning tool, like Advanced System Care or CCleaner.

  • Launch Internet Explorer 11
  • On the right-hand side of the browser, click on the gear icon – the Tools icon
  • Go to Safety and select Delete Browsing History
  • Uncheck all options except the Temporary Internet files and website files
  • Click the “Delete” button.
  • The Delete Browsing History window will disappear and your mouse icon might go busy for a while.

Bonus Tip: Set cache size at 200-250 MB. A larger cache won’t speed up browsing. Internet Options> General tab> Browsing History> Settings> Disk space to use.

Disable Add-ons

  • Open Internet Explorer and select the Tools button
  • Click on Manage add-ons
    How to disable Add-ons in Internet Explorer 11
  • From the drop-down menu choose “All add-ons
  • Select each add-on that you want to remove and click on Disable.

Scan your system for errors

Another solution would be to run SFC/scannow command in the Command Prompt to check your system for errors. And you can scan your system with a good antivirus software.

Reset IE to default level

Finally, go to Internet Explorer, click Tools > Internet Options > Security > Reset all Zones to Default level.

These tweaks should help you fix your slow Internet Explorer and improve your browsing experience.
