Every second Tuesday of every month Microsoft Releases a bunch of security updates!  

 
 
 
 What does Patch Tuesday mean? and what does it do for you?
Patch Tuesday is a name used to refer to the second Tuesday of each month, when Microsoft releases fixes for known bugs in the Windows operating system and its related applications. Patch Tuesday was introduced by Microsoft in 2003 as a way of simplifying patch management. Scheduling patch release allows system administrators to plan for the day and install several patches with a single reboot. While Patch Tuesday is reserved for standard bug patches, critical code fixes can be sent out at any time. Administrators sometimes refer to Patch Tuesday as Black Tuesday.
 
Although Patch Tuesday is designed to simplify patch management, sometimes the number of patches released on that one day can be overwhelming if any of them cause system problems. When a number of computers that are connected to the Internet all reboot within a certain period of time, this can also strain a network and lead to outages.
 
Critics of Patch Tuesday also contend that it provides opportunities for hackers, particularly when a security hole has been announced to the public. Because of Patch Tuesday, hackers will know how long they have to exploit the vulnerability before it is repaired.This phenomenon spawned the creation of a related term, Exploit Wednesday, to refer to the day when hackers get to work on unpatched vulnerabilities in Windows.
 
 Are the Updates absolutely necessary   
Although it's perfectly natural to get annoyed by Windows' seemingly endless ‘New updates are available' alerts, it's not a good idea to ignore them. You do so at your own risk.
   

The vast majority of updates (which arrive on your system courtesy of the Windows Update tool) deal with security. Microsoft routinely patches newly discovered holes, adds malware definitions to its Windows Defender and Security Essentials utilities, bolsters Office security, and so on. And don't forget the occasional Windows hotfix, which may address serious issues such as random system lockups. In other words, yes, it's absolutely necessary to update Windows.

   
One thing to remember about Windows Updates though!  
  • Windows 10 updates are cumulative. The monthly security release includes all security fixes for vulnerabilities that affect Windows 10, in addition to non-security updates. The updates are available via the Microsoft Update Catalog.
  • Starting in March 2017, a delta package will be available on the Microsoft Update Catalog for Windows 10 version 1607 and newer. This delta package contains just the delta changes between the previous month and the current release.
  • Updates for Windows RT 8.1 and Microsoft Office RT software are only available via Windows Update.
  • In addition to security changes for the vulnerabilities, updates include defense-in-depth updates to help improve security-related features.
   
 What can I do to make sure my updates are working?  
Start, type Windows Update, and press Enter. (In Windows XP, head to the Control Panel and seek out Windows Update.)
 
Step 2. Next, click the Change Settings option, and choose Install updates automatically. Click OK to finish the process. Now, the only time you'll hear from Windows Update is when it requires a reboot.
