Why have Microsoft warned users when updating to their new system version?

MICROSOFT have rolled out their latest update the May 2020 named as Windows 10 2004. This first update of the 2 yearly updates always seem to cause issues with specific chipsets, software & other vendor issues and this is just the same, SO WHY DO THEY RELEASE IT? WE ALL ASK.
Mainly security vulnerabilities are the answer to that question.

These are the reasons Microsoft are warning users NOT to update.

Several glitches found in the latest operating system upgrade. While Microsoft will try to patch security flaws, performance issues and bugs in each of its operating systems …this will often lead to more being issues being introduced. Since updates come thick and fast (every Tuesday) the fix is usually found and repaired within 7 days.

Millions of people who are working from home, other who use their systems for entertainment and keep in touch with all of their friends and family– the timing couldn’t have come at a worse time. Fortunately, Microsoft has been upfront and published a list of issues that have been found inside the new version of Windows 10 May update. Found here.

Some of these issues are minor and shouldn’t be enough to put you off installing Windows 10 2004 update – like a bug in the system that stops some monitors with a variable refresh rate working as expected (the dreaded black screen which happened in each Windows 10 version up to now) this won’t be an issue if you’re not using a monitor with an optional high refresh-rate panel but not everyone has these.

Some issues are serious enough for Microsoft to warn users: “We recommend that you do not attempt to manually update”.

A massive number of Windows 10 users allow their operating system to update automatically – which is a default setting – meaning it will probably be too late for them. While automatic updates can be incredibly useful (if the settings are correct) it keeps your machine guarded against the latest malware attacks and protected against other bugs in the system …it can be a problem as it means you don’t have the option of skipping an operating system update with dangerous or frustrating glitches.

One of the issues found inside the Windows 10 May 2004 update, causes issues when connecting multiple Bluetooth devices simultaneously to your machine. In all honesty I don’t know more than a handful of people or businesses that do this.

Another glitch relates to Intel GPUs, while unplugging certain Thunderbolt devices from your system, black screens after the update has always been a major issue in all of the released updates so far.

The full list of everything wrong in Windows 10 2004 update can be found below, taken from the Microsoft help-page:
