Quote:Microsoft releases new feature updates for the company's Windows 10 operating system twice a year which introduce new features and changes.
While there are plenty of good reasons not to install feature updates right away, there is also some confusion on how to download and install feature updates for Windows 10.
Microsoft released the Windows 10 October 2018 Update on October 2, 2018. The company published How to get the Windows 10 October 2018 Update on the same day, and revealed in it that users just have to press the "check for updates" button in the Settings app to download and install the update.
Problem is, this won't work for all systems because the update won't be offered if Microsoft's machine learning algorithms have determined that the installation of the update may be problematic on the device.

Quote:If we detect that your device has a compatibility issue, we will not install the update until that issue is resolved, even if you "Check for updates".

Tip: make sure that your system has enough free storage space to install the Windows update. Check out our tips on freeing hard drive space here.
