Microsoft will be releasing a record number of patches tomorrow, August 10th. A total of 14 bulletins will be released, addressing over 30 issues. Information on these patches can be found here.
So if you are a Windows user be aware that there will be a lot of updates recommended for your machine tomorrow. As always, I recommend that when this many patches come out at once, it's best to wait a bit before updating your machine, just to make sure there aren't any problems or compatibility issues with your software. If you want to do this you can turn off Automatic Updates from your control panel, just be sure to remember to turn it back on once you've installed the patches!
