I have no problem with Internet Explorer being listed. I removed it shortly after the Windows 10 install because I thought I wouldn't need it. But, as it turns out, I did, because it was necessary for me for the install an old Adobe Photoshop program I have. I had to re-install it in order for the install to complete.
As pictured; Microsoft Edge and Edge Chromium are both listed by CCleaner. Does this mean I have 2 versions of the browser installed? I checked, and couldn't find any way to remove an old version. There is just one version listed in the add and remove programs section.
This is an old Vista laptop that I upgraded from the Windows 10 ISO that windows offered. I wasn't sure it would work from Vista to 10, but everything looks OK and is in good working order.
