Microsoft released it's first super patch. The super patch, or Update Rollup 1 for Microsoft Windows XP officially, bundles 22 critical updates previously released.
With the recent security risks from unpatched Windows machines, Microsoft had to change the patching strategy.
At the same time, Microsoft promised alot more things. Firstly, there will only be monthly patches instead of weekly, making the life of system administrators alot easier. Secondly, the patches will be smaller and very easy to rollback in case of a problem.
