How to receive (email, RSS) Notifications about Windows Update

I know of three ways to get this info in various methods:

1. TechNet Technical Security Notifications

• You can receive these via RSS or Email.
• Varying levels of information depending on what you want/need to know.
• Only support MS products. But supports all currently supported MS products.

2. Microsoft Security Newletter

• More of a power-user informational alert.
• Monthly notification email with released bulletins and patches and other security related information from MS.
• Still limited to MS patches and information.
• Email only.

3. Shavlik XML update bulletin

• Provides notifications of updates for wide array of common software, including all currently supported MS OSes and products, several different browsers, common plugins, media players, chat clients, programming tools, etc.
• Email only.
• May be a day or two later than other notifications as each patch is tested and approved by Shavlik/VMWare prior to publishing.

UPDATE 2/17/2015:

Shavlik now offers notification via Twitter as well as an RSS feed of their patch file updates which, as before, include more than just Microsoft products.

For all their update methods, see this KB article: https://community.shavlik.com/docs/DOC-23176

• Shavlik XML Twitter: https://twitter.com/ShavlikXML
• Shavlik Protect Blog: http://protect7.shavlik.com/
• RSS Feed of the Shavlik Protect Blog: http://protect7.shavlik.com/feed/

Both the Blog and RSS Feed contain full details on the patches included in the new XML file, while the Twitter account updates with links to the most recent Shavlik Protect Blog entry, and Shavlik states their intent to release new XML files the same day patches are released.

As before, you do not need to be a Shavlik customer or subscriber to uses these notification methods.

Notes:

While these are just notifications, using a WSUS server or a third-party tools such as Shavlik (which I've used extensively) allows you to manage patching on as automated or manual a level as you like, and both WSUS and Shavlik will make deployment much easier.
