As many of you have discovered by now, Microsoft surreptitiously added the Flash player in an update well after the upgrade to Windows 10. It isn’t possible to remove it using the standalone uninstaller from Adobe as in previous versions as this is now baked into Edge, Microsoft’s new browser… almost.
It is possible, to remove the plugin, but it requires a fair bit of manual labor to do so. First, go to Edge and select options (the . . . ) and follow the steps to make sure the Flash is turned off.
Now the fun part
Microsoft has set ownership permissions for all the files we need to delete so that none of them can be removed without changing them first. The files we need to delete are located in the following places :
In each of these directories, you should see these files :
You may also see FlashInstall.log. Trying to delete these will give you a permission denied error. To change that, follow these steps. Be advised that you’ll have to follow these steps for each of those files individually as Microsoft has made it very difficult to collectively apply the same permissions by inheritance.
You’re now the owner of the file to delete, but that’s not enough. You need to change the principal access.
You’ll get a warning dialog. Just click “OK” on it and click on “OK” on the permissions box too. You can now delete that file.
Cleaning the control panel
You’ll still see the FlashPlayer utilty in the control panel so to remove that, go to C:\Windows\SysWOW64 and delete:
Keep in mind, however, that there’s nothing preventing Microsoft from installing Flash on your system again. You don’t own proprietary software. Yes it’s your computer and you may pay for it (well, Windows 7, since this is a free upgrade), but you don’t own it if you can’t control what’s on your system how it gets there. Further, Windows 10 is as close to Software as a Service as you’ll get while still having something installed. It’s the most invasive in terms of your privacy as well, but there are mitigations you can take.
For your next operating system, may I suggest Linux Mint?
