Just a heads up that SIW Portable has been retired from the PortableApps.com App Store and won't be available in the platform's app store or updater. The publisher decided to cease making freeware personal versions available. The version we have from 2011 will still be available for direct download from our site for the time being but will not function on Windows 8, 8.1 or 10. It is no longer supported by the publisher or by PortableApps.com.
Paid versions are available from the publisher for those who are interested. Alternatives are available in PortableApps.com Format within the Utilities section of the app store.
