I have Windows 8 installed, joined the computer to our domain and logged in as the domain administrator.
Any time I try to open an app from the Metro UI I get the following message:
This app can't open
[App name] Can't be opened using the Built-in Administrator account.
Sign in with a different account and try again.
If I try to run IE from the Metro menu I get that message but if I switch to desktop mode, I'm able to open IE.
Very strange, not sure if this is expected behavior or a bug.
