Today is Patch Tuesday. March's patches consist of 5 updates that correct 23 unique security issues across Microsoft Windows operating systems and some other Microsoft software.
What Do These Security Updates Do?
These patches from Microsoft update several individual files involved in making Windows and other Microsoft software work.
Do I Need These Security Updates?
You need these updates if you're running any supported edition of Microsoft's operating systems, 32-bit or 64-bit. This includes Windows 8 (as well as Windows 8.1), Windows 7, Windows Vista, and Windows XP. Server versions are included. Microsoft Silverlight is being updated to correct a security issue as well.
Some of these updates correct issues so serious that, in certain situations, remote access to your computer may be possible without your permission. These issues are classified as critical, while some others this month are less serious and classified as important.
See Microsoft Security Bulletin Severity Rating System for more on these classifications.
Are There Any Non-Security Updates This Month?
Yes, including non-security updates for Windows Vista, Windows 7, and Windows 8 & 8.1. Also, as usual, Microsoft is pushing this month's update to the Windows Malicious Software Removal Tool.
Some Microsoft Surface tablets are also getting driver and firmware updates, among other fixes. You can get all the details on the Surface, Surface 2, Surface Pro, and Surface Pro 2 update history pages.
There may also be non-security updates included this month for Microsoft software other than Windows. See the Non-Security Updates links below for details.
Automatically install: via Windows Update.
Manually install: via the individual Bulletin IDs listed in the Microsoft Security Bulletin Summary for March 2014. See Do I Have 32-bit or 64-bit Windows? if you're not sure which downloads to choose.
Next Patch Tuesday: will be April 8, 2014.
Patch Tuesday Problems
While updates from Microsoft rarely result in widespread problems with Windows itself, they do frequently cause specific issues with software or drivers provided by other companies.
If you haven't yet installed these patches, please see How To Prevent Windows Updates From Crashing Your PC for a number of preventative measures you should take before applying these updates, including disabling fully automatic updates.

Be sure to let me know exactly what's happening, what version of Windows you're using, and what if any errors you're seeing, and I'd be happy to help you out.
Note: I used to allow commenting on this post about Patch Tuesday problems but it got out of hand very quickly, spam was a problem, and it was difficult to actually help anyone out. So, as you can see, I am instead posting on Google+ about Patch Tuesday and helping people there. I understand not everyone will like this change but it solves a lot of problems, most importantly it'll allow me to better manage comments, meaning yours is more likely to get a personal answer. That's a good thing!
