Keyboard & mouse not workibg,.....alternatlves?

My keyboard, trackpad and mouse stop working. After a day or so they re-connect.
No one has been able to offer a solution. So I and have to use the onscreen keyboard and touch with a basic stylus --- very slow, as now.

It would help if I had answers to the following

1. how do I right click with the stylus, keyboard? for example to use Cmd prompt with admin, to run sfc
2. how do I get Cortana to launch apps / files commands on the PC instead of always defaulting to the web?
3. how do I get Cortana to obey speech commands like run, open, select, enter, save?

Windows 10 Anniversary, 2 in 1

From memory to right click on a tablet with the stylus you would keep the stylus over the file you wish to right click longer than you would normally. Can't help with Cortana as I don't use it

Thanks for reminding me of that .... my mind was stuck on double tapping, but got it working now. Apart from solving the Keyboard lssue I now have to find how to get speech commands to work.
