A handful of important bugfixes:

• Fixed issue with detecting user's display UI when enforced by Group Policy, fixed typo in one of the registry paths
• Fixed issue with extra double quote at end of VBScript command in function Execute-ProcessAsUser (caused issue in Set-ActiveSetup as well)
• Fixed issue with Enable-TerminalServerInstallMode and Disable-TerminalServerInstallMode expecting a successful execution of change.exe to return 0 when it should really be 1
• Fixed issue with Execute-MSI so that Get-MsiTableProperty is only called when the file being executed is an MSI and not when it is an MSP
• Fixed issue in Invoke-HKCURegistrySettingsForAllUsers where a registry hive would fail to unload because of an active memory reference by manually invoking garbage collection
• Fixed issue where registry key for deferrals was not being set correctly
• Fixed issue in Show-InstallationWelcome where blocking "notes" would stop script execution
• Fixed issue where System.Threading.Mutex class does not have Dispose() method prior to .NET 3.5 so will call Close() method instead. This also fixed issue with blocked app message not showing on Win 7 .NET 2.
• Changed StubPath registry type to 'String' in Set-ActiveSetup
• Improved comments and documentation
