Security settings within the Java plug-in

Starting with version 7 update 10, the Java plug-in has some new security options available.  To access the Java settings, access the Java icon under the Control Panel and then click on the Security tab.

java_security

The initial checkmark option is to enable or disable the Java component within a browser.

java_security_2

The slider controls when a confirmation warning will be displayed.  The medium security level will allow unsigned Java apps to run, but only if the Java version is considered secure.  Setting the security level to very high will prompt the user for permission every time a Java app, signed or unsigned, attempts to run in the browser.  If the Java version is deemed insecure, unsigned apps won't run at all regardless of what the user decides.

Windows Server 2012 and removing binaries from the local disk using Features on Demand

By default, the files required for adding roles and features within Windows Server 2012 are stored under C:\Windows\WinSxS.  An option is available via PowerShell to remove certain binary files from this folder.  If a particular file is required again in the future, the operating system will attempt to obtain it via Windows Update.  One advantage is less maintenance; even if a role or feature is not being used, future updates will need to be installed to patch the binary files in question.  It can also help if free disk space on the system partition is an issue.

To remove the binary files from the local disk, use the switch –Remove with the Uninstall-WindowsFeature cmdlet.  The install state column using the Get-WindowsFeature cmdlet should display a value of “removed” if the request was successful.

Files should be missing from the WinSxS folder if compared between a before and after snapshot.
