When you try signing in to Skype for Windows desktop, you may sometimes get a blank blue screen displaying only the Skype logo. (You might also get a blank white screen if you're trying to sign in with a Microsoft account.)
If you are experiencing this issue, the first step is to make sure you've upgraded to the most current version of Skype.
If updating Skype doesn't solve the issue, try the following to resolve it:
Before proceeding further, make sure that:
Try resetting your Internet Explorer settings. You can do this easily by clicking the Reset Internet Explorer settings link on the Microsoft support webpage.
Skype takes its browser settings from Internet Explorer, so you’ll need to reset its settings even if it’s not your primary browser.
If you have uninstalled Internet Explorer, you will need to install its latest version and reset your settings.
If this doesn't work, delete the contents of your Temporary Internet Files folder, by clicking the Fix this problem link on the Microsoft support webpage.
To create a shortcut for the Skype sign-in window, follow these steps*:
"C:\Program Files\Skype\Phone\Skype.exe" /legacylogin
or if you have a 64-bit operating system:
"C:\Program Files (x86)\Skype\Phone\Skype.exe" /legacylogin
*These instructions don’t apply, if you sign in to Skype with your Microsoft or Facebook account.
To be able to clean the login files on you machine, you will need to download and run (double-click) the Login Cleanup file. By choosing to downloading and run this tool you are accepting the associated End User License Agreement.
