What would happen if I turned off the automatic Windows updates? On Windows 10, quality updates (or cumulative updates) download and install automatically as soon as they become available. Although this automatic approach allows devices to receive security updates to patch vulnerabilities, improve performance, and bring enhancements without user interaction, it is perhaps one of the most controversial features.
Cumulative updates are installed automatically when Windows decides to do it. This can be extremely frustrating for Windows 10 users as they are often forced to restart their machine at an inopportune time.
Automatic updates have their pros, for instance, an out-of-band emergency Windows patch is currently being rolled out by Microsoft to fix a critical security bug that enabled hackers to take control of a user’s personal computer remotely.
The bug known as PrintNightmare was revealed last week after security researchers accidentally published a proof-of-concept for the exploit. Now, the company has rolled out an emergency patch to fix this bug that is listed as ‘critical’ on its website.
However, these updates typically contain these bugs that can negatively affect the experience in many different ways. For example, they could break existing features, introduce driver and application compatibility problems, Blue Screen of Death (BSoD), and they require a restart to complete the installation that can disrupt the user workflow.
If you tend to see more problems than benefits during updates, or you have a good reason to use a computer unpatched, depending on your edition of Windows 10, you can disable automatic updates using the Settings app or permanently with the Group Policy or Registry.
However, Microsoft Regional Director, Troy Hunt says this is a very dumb idea,
Why is malware effective? Because of idiotic advice like this: "Stop Windows 10 from automatically updating your PC" https://t.co/cRygHYMPNh
