There are a few browsers that Windscribe isnt included to bundle with such as Opera (I know it has its own VPN but I find that somewhat sinister of them as I dont have any ability to select where) and the Microsoft Edge. (Im giving Microsoft a slap for that)
Ive have issues using Windscribe, and a number of other VPNs in the past, but it is due to a beta Tech program on my PC, but when it does work..FANTASTIC
