Why has Skype automatically updated?
At Skype, we regularly release updates to our software so that we can introduce new features, improve existing ones and fix bugs.
We always recommend that you use the latest version of Skype, which is why Skype automatically updates to the latest version by default. If you prefer to choose when to upgrade, you can switch off automatic updates.
Disable automatic updates on Windows desktop.
Disable automatic updates on Mac OS X.
With automatic updates switched off, you can check for available updates whenever you like and install them yourself. Just click Help > Check for updates from Skype on Windows desktop, or Skype > Check for updates on a Mac.
If you want to know what’s in the latest release before you decide to upgrade, you can find out in what’s new in Skype for Windows desktop and what’s new in Skype for Mac.
From time to time we retire older versions of Skype. When this happens, even if you've switched off automatic updates, you won't be able to sign in until you upgrade to the latest version.
What happens to my Skype Credit or subscriptions when I upgrade?
Updating Skype to the latest version does not affect your Skype Credit balance or subscriptions. Any products you've purchased remain in your account and available to use just as they were before the upgrade.
