How to run Skype in Windows 8 Release Preview

UPDATE: Skype has released a hot fix for these issues so instead of following these steps please re-install/update the latest version of Skype.

Fix login issue:

• Stop Skype (it doesn't stop all the way in Win8 RP so kill it using Task Manager/Process Explorer)
• Go to C:\Users\YourUserName\AppData\Roaming\Skype
• Delete the following folders and files
•  shared_dynco
• shared_httpfe
• shared.lck
• shared.xml

Fix high CPU usage:

• Run Process Explorer
• Find Skype from the running processes
• Double click the Skype.exe process
• Go to Threads tab (click ok on the warring, it only shows up once)
• Sort the running threads by CPU usage and kill the one that is consuming highest CPU resource
• Skype will be still running but it will consume less CPU resource than before
