Windows TAP reset tutorial
Sometimes if the local user changed its DNS or ipconfig setting, the outline will failure to run even though you uninstall and install it again. It happened when you didn't delete windows TAP correctly. Do we need add tutorials to tell how to reset TAP and re-install outline on the windows os?
I seen this issue 3 times already.
@sailosha Good suggestion. There is definitely a case to be made for better documentation on configuring/removing the TAP device. I'd also like to automate this, mostly the uninstall part.
@lgg Unfortunately, the tools bundled with tap-windows6 can only remove devices by their "hardware ID" which devices from other VPNs may share. We definitely do plan to fork/overhaul those tools at some point which would make this possible.
@sailosha I just realised that you're right, the installer currently does not try to "fix" the TAP device's subnet if the user has manually changed it. That would be straightforward and would help some users. Thanks for the suggestion.
@trevj sorry, I didn't really understand.

As I know: Outline Client creates TAP-adapter named 'outline-tap0' during installation, this TAP adapter is used only by Outline Client. In https://github.com/OpenVPN/tap-windows6 README:
tapinstall remove TAP0901
So I think that tapinstall remove outline-tap0 should work fine in this case. Is it right?
@lgg Yes but if you also have, for example, the OpenVPN client installed then any network devices it has created will also be removed - as they share the same hardware ID.
Unfortunately, I don't know of a way to remove just outline-tap0 via the command line. Yes, this is slightly ridiculous.
Or we may use builtin stuff on windows for removing the TAP adapters: Link
We can detect the problem and integrate an automated script in Outline and prompt users for using it)
Mac OS should have something similar since it is Unix-based.
@LBYPatrick Thanks for the tip but unfortunately I get this error:
C:\Windows\system32>netsh lan delete profile interface=outline-tap0
You do not have sufficient privileges or the profile on interface "outline-tap0" is a group policy profile.
