Solution 5 – Remove your browsing history and cache

If Microsoft Edge won’t open, the problem might be caused by your browsing cache and history. To fix the problem, you need to clear your cache by using a third-party tool such as CCleaner. CCleaner is a great tool for removing junk files, and you could also use it to remove Edge’s cache.

Another tool that can help you with this problem is Yamisoft Windows 10 Manager. Simply download the tool, run it and navigate to Network > Microsoft Edge Manger > Reset Microsoft Edge > Reset to remove your history and cache. After using any of these two apps, the problem should be resolved.

Several users reported that you can also clear the cache using Edge. According to users, you might be able to open Edge by opening any link directly. To do that, simply pin Edge to your Taskbar, right click it and choose any link. After doing that, Edge should start normally. Now you just have to clear your cache by doing the following:

  1. Click the Menu button in the top right corner and choose Settings from the menu.
    Microsoft Edge opens then closes
  2. In Clear browsing data section click on Choose what to clear.

Solution 6 – Close all other Edge processes

  1. Pres Ctrl + Shift + Esc to start Task Manager.
  2. When Task Manager starts, look for any Edge processes running in the background. Right click Edge’s process and choose End Task from the menu. Repeat this step for all available Edge processes.
