Microsoft is gearing up for Skype 8, and official public release is expected for September 2018. Which also means the support for Skype 7 aka Skype Classic version will end and users will be forced to move to Skype 8. Although Microsoft is maintaining its stand that Skype 7 Classic will be discontinued from September, we believe the Skype 7 classic may continue to work even after that, because Skype 8 is only designed to work for Windows 7 and onwards.
The current version of Skype that most users are running is Skype 7 Build 18.104.22.168 or build 22.214.171.124, both the versions are stable version and have classic UI, which most users are used of. Unfortunately, just like every major update comes with plenty of headaches for users, Skype 8 is no exception here. From missing features to unwanted change in UI, Skype Community forum is full of such complaints from Skype 8 insider preview users.
That gives the perfect reason for one to go back to old version of Skype, If for some reason you have updated to Skype 8 preview release or after September 2018 your Skype got auto upgraded to Skype 8 then here are the download links for Skype 7 Classic version.
