While Windows 10 was still in the form of Technical Preview, Microsoft was advising users that glitches and problems were to be expected. One of them was the slow performance of the default Internet Explorer browser.

Microsoft confirmed that IE 11 is the last version of Internet Explorer. Therefore, if you want to make it work, read this article and find out how.

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.

Internet Explorer 11 has aimed to be the first browser to make Internet connections more secure and reliable by reducing the use of vulnerable cipher suites (ex. RC4) and by using the latest security standards, TLS 1.2, by default.

One reason might be that many web pages are not officially supporting Internet Explorer anymore. Internet Explorer 11 is hardly being maintained and is merely used for Intranet websites and apps that require ActiveX controls.

Some users consider that TLS 1.2 is actually causing IE 12 to work slow, but secured. By any means, if you enjoy IE 11 and want to make it work on your device, check out the following tips and fixes to apply now.

How do I speed up Internet Explorer?

1. Opt for a faster browser

Internet Explorer is no longer officially updated by Microsoft, having been replaced with Microsoft Edge as the default browser. That being the case, replacing it with any other browser is pretty much an upgrade.

That is why, if you’re are to replace Internet Explorer, might s well go for the best alternative on the market, and it is called Opera.

2. 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 good antivirus software.

We recommend you use a security tool that is stable and has a detection rate. Some of the best antivirus software available are optimized for browsing and they can actually help improve your speed rates while keeping your PC secure.

You can also run a scan with Windows Defender, but third-party tools are generally able to detect more threats and have a lower false-positive rate.

3. 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

  • Go to Safety and select Delete Browsing History
  • Uncheck all options except the Temporary Internet files and website files
  • Click the “Delete” button.
