Not only two of my friends have problems with Windows 10 and Skype but a browse of the Internet shows many others have such problems with Skype. I will not allow the older version of Skype to be replaced by the fancy new version myself. My clever IT pal claimed when he installed the new version it would not handle messages. Also another friend and many on the internet cannot hear voices since they are garbled etc. It took a friend a long time to cure the interference to my voice even when she replaced the new version of Skype with the older version. She had to try umpteen of the Win 10 Trouble shooters in the Control Panel to control the interference. Yet I had no such problems with other friends on Skype.
