I moved from win 7 to win 10 and now I have to right click everything How can I fix this?

[Windows Central Question]

I can only access the internet by going to computer management on the start menu, clicking on help then tech center website.. Cortina is not on the task bar - but when I open firefox it appears. unfortunately, because I have to right click most everything that does not add it to the task bar permanently.

Please join and specify the following in this thread:

1) Which device did you upgrade i.e laptop, all-in-one, desktop?
2) What sort of mouse if you are using one i.e a ps/2 mouse, usb mouse etc.

I have only seen this behaviour in ps/2 mice hence why I'm asking .

So depending on the device it could be anything really...
