Here’s the mail I got recently for my problem
This problem is affecting both of my windows computers as of yesterday.
I am an IT guy and have the following notes:
• login.live.com fails with ERR_CONNECTION_RESET on IE and Chrome from Windows 7 and 8
• login.live.com works properly from all browsers ON MY MAC AND ON MY ANDROID PHONE
• It's not my network or router: I took both computers across town and connected to a business network with a different ISP and had the exact same problem
• Access to login.live.com works in safe mode on both Windows computers
• Both Windows computers are fully up to date
• I installed MalwareBytes and ran a full scan; no malware is found (and no other symptoms of malware are present)
• I did a full Reset of IE Settings, cleared the caches of all my browsers: problem persists
• I installed a new network card in the Desktop windows computer: problem persists
• I reset the TCP/IP Stack: problem persists
I've done everything I know to do, I'm convinced this is a server-side issue. If anyone has any other ideas how to fix this, please let us all know!

Thanks

I think this problem is due to some registry issue. Try using CCleaner or Malwarebytes and if they don't work try this website err_connection_reset windows 10

if you have any the problem please contact us
Thanks
