Windows Messenger

Okay...I have many ideas that may help Microsoft in their new Windows 10...and am always standing with Microsoft till the end of this Preview. Windows Messenger....The idea was out...just when I was sitting in my dads office and I saw all those busy people working unstoppably from 9 to 5...and I noticed too that every time my dad wanted any important paper from someone or any request he always used to call that person under the specific line of the companys network, until one day the line of those office phones stopped working and they bought a technical worker to solve the problem ASAP.....anyway, then everything became more harder when every one started using e-mails, Facebook messenger, Whatsapp, or even calling other people through their personal phones just for those important needed papers or stuff for job....so on....so i thought of why wont Microsoft make a messenger integrated with Windows 10...that links computers together. I mean because now their is a task manager were it can leads you to whatever programs you opened or to your desktop fast....so at the really right bottom of the screen were you press it and it takes you to the desktop...I suggest that Microsoft turn that button to the Windows Messenger button....where it links people in the same network. I open that messenger and add computers (Their Windows Accounts) and then see if my friend opened his computer( it gives me the sign of available)  and then I send him to join me online in the game....or simply ask my company partner who is working 3 floors under me...to e-mail me a needed paper fast...just by typing for him at the bottom right. And it will pop up for him fast...without using  phones.....it just goes so fast and smooth ! ......I made a really simple photo by Paint just to show so far what am I imagining.....Thank you!
