UPDATE: February Security Updates will be included with March Update 2017.
Traditionally Windows Updates are installed on the second Tuesday of each month (or the Wednesday that falls after the second Tuesday of each month for us Aussies). This month’s patches will be delayed after some last minute issues were discovered.
This month’s patches will include an update for a 0-day vulnerability in SMB which is the file sharing component of Windows.
Most computers will automatically update Windows each month, but my advice is to do a manual check to ensure that Windows Update is working correctly and patches are installed. Malware is known to disable Windows Updates as a method of staying persistent on your device.
