Just reinstalled windows 10 and the Skype website no longer has a windows download, just the new "app" which is laggy as fuck.

I wouldn't use Skype but it's needed for business contacts, is there to get a regular download for the original Skype program and not the app?

I could be wrong but it looks like the only way to obtain Skype for Windows 10 is through the App Store. I've checked several sites and help sites and they all direct you to the App Store.

If you're having issues with Skype, I believe you can open a support ticket with Skype found here; https://support.skype.com/en/skype/windows-desktop/

I believe you can also use it in the browser as well. That is more like the original.

Give this a shot: https://skype.en.uptodown.com/windows/old

Within the drop-down menu, choose Get Classic Skype.

Just did this on 10

Vouch.
