Should You Install Windows 10 Version 20H2

According to Microsoft, the answer to this question is absolutely “Yes”. At first, Windows 10 20H2 (October 2020 Update) now is broadly available as an optional update. Then, this update is safe enough for installation.

It’s not recommended to install the new update as unknown bugs, errors, and compatibility problems would occur during the initial rollout of a new release. Generally speaking, you will be informed that the update is ready on your device in the Windows Update Settings when a new version of the OS releases.

Tip: After a new feature update turns available, it is recommended to wait for three to four quality updates at least before installing it.

If you don’t receive the notification, you shouldn’t force to update with the Media Creation Tool, Update Assistant, or ISO file. Otherwise, you may run into issues like This PC can’t be upgraded to Windows 10, This PC can’t be upgraded to this version of Windows 10 because of a service or driver that’s not ready yet, and other similar errors.

Besides, you need to note that Microsft is limiting the availability at present. It means that the feature update is still not entirely compatible with many hardware configurations. What’s worse, the software giant has revealed some errors at the health dashboard website during the rollout.

The answer to whether you should install Windows version 20H2 also depends on the currently installed release on your device. For instance, if you are running the version 2003, you can install version 20H2 with minimal to no risks because the two versions of OS have the same core file system.

The update only needs an enablement package to activate the new features delivered in a dormant state on the version 2004 during the development cycle. Hence, the update installation process is fast and painless without reinstallation.

However, upgrading from an older release in the previous year requires a full reinstallation. Additionally, this process may result in plenty of unexpected problems including unknown and known issues, as well as software and compatibility errors.
