Hello. I've recently upgraded from Windows 8.1 to Windows 10 Home. My laptop is a Lenovo IdeaPad Y510p 64bits. The problem is that weekdays don't display correctly. My taskbar shows correctly that today is August 8. If I put the pointer over the date I can see "Saturday, August 8 2015" that is OK. But if I click on the date, the computer shows a monthly calendar where August 8 2015 is Sunday.
