It seems that Microsoft is almost always too late to the party when it comes to application development. After years of widely unpopular Internet Explorer dominance, they introduced Microsoft Edge accompanying Windows 10. Even though this browser has a lot of goods to offer, it still trails back behind the competition.

And, even though it’s hard to believe, it has too much performance issues for a native application. One commonly reported problem concerns the extremely high CPU usage of the Content process belonging to Microsoft Edge.

Solutions for this problem are to be found below, so feel free to check them out and, hopefully, bring down the CPU usage to more normal numbers.

FIXED: Microsoft Edge Content uses too much CPU

  1. Clear browser’s cache
  2. Scan for malware
  3. Run Edge without extensions
  4. Disable built-in Flash Player
  5. Try obvious or less obvious alternatives

Solution 1 – Clear browser’s cache

We all know that Edge was Microsoft’s intention to challenge Chrome and Firefox in regards to speeds and lesser resource consumption. It did initially but updates and feature-rich additions which come with them took a lot of its light nature. Now, even the locally stored cache can cause abnormal memory and processor spikes, even with only one tab opened.

So, let’s start with the cached data. We suggest deleting it completely, with passwords being an only exception. You can erase them as well if you’re using a third-party application or extension to store passwords.

Here’s how to clear data from the Edge browser:

  1. Open Edge.
  2. Press Ctrl + Shift + Delete.
  3. Check all the boxes and click Clear.

Solution 2 – Scan for malware

The presence of a malicious infection might be another possible reason. Have in mind that we’re roaming in the dark and trying to cover all possible reasons. Now, even though this is an unlikely scenario, there are slight chances that some PuP was unwillingly installed. We all heard about the browser hijackers used to take your resources for cryptocurrency mining.

In order to avoid this, we advise scanning for malware and, in addition, using a specialized anti-PuP tool called AdwCleaner by Malwarebytes.

Here’s the whole procedure for the Windows Defender and AdwCleaner combo:

  1. Open Windows Defender from the taskbar notification area.
  2. Choose Virus & threat edge content process high cpu
  3. Choose Scan edge content process high cpu
  4. Select Windows Defender Offline Scan.
  5. Click Scan now.
  6. Your PC will restart and the scanning process will commence.
  7. After it starts again, download Malwarebytes AdwCleaner, here.
  8. Run the tool and click Scan edge content process high cpu
  9. Wait until the tool scans your system and click Clean & Repair.
  10. Restart your PC.

Solution 3 – Run Edge without extensions

Browser add-ons or extensions are of the utmost importance for so many users. Starting with the ad-blockers and moving to various helpful utilities — every serious browser developer needs to make them available. Edge started without extensions, but now that it has them, users are quite satisfied with what Microsoft’s new browser has to offer.

However, even though all of them come through a standard inspection, they still come from a third-party developer. And thus might or might not be well-optimized.

With that in mind, another viable troubleshooting step is to disable all extensions and look for changes. Later, you can, with the system of elimination, find out which one is causing high CPU usage and memory leaks.

Here’s how to disable extensions in Microsoft Edge:

  1. Open Edge.
  2. Click on the 3-dot menu and open Extensions from the edge content process high cpu
  3. Disable all extensions individually and restart the browser.

Solution 4 – Disable built-in Flash Player

While we’re at extensions, third-party flash players become abundant since, these days, almost every browser has the built-in Flash player. And, judging by some reports, this Flash player is the culprit for the Content process’ abnormal CPU usage. What you need to do is disable it temporarily and look for changes in the Task Manager.

If the problem is persistent, we can hardly be of any help anymore. But, if the CPU usage of the Content process drops, we advise disabling the built-in flash player permanently and moving to third-party alternatives.

Here’s where to disable the built-in flash player in Microsoft Edge:

  1. Open Edge.
  2. Click on the 3-dot menu and choose the Advanced tab from the left pane.
  3. Under the Adobe Flash, disable the “Use Adobe Flash Player” edge content process high cpu
  4. Restart your browser and install a third-party flash player.

Solution 5 – Try obvious or less obvious alternatives

Finally, until Microsoft provides a viable and permanent resolution for the problem at hand, you can stick with Google Chrome, Mozilla Firefox, Opera, or any other browser. There’s a reason why Edge still is, despite all feature additions and updates, far behind Chrome in the global browser market share.

You can also extract all bookmarks to a new browser and speed up the transition substantially. Here’s how to do it:
