As we all know, Microsoft is releasing Windows 10 patches from time to time for fixing bugs and for adding new stability improvements, security add-ons and features or dedicated capabilities.

Anyway, in rare situations a certain update might get stuck or blocked by the Windows system and that’s when you will most likely receive the following error message: ‘We couldn’t connect to the update service. We’ll try again later, or you can check now. If it still doesn’t work, make sure you’re connected to the Internet’.

This error prompt is displayed when the update cannot be completed – it can be an internet connection error, a corrupted system file, a limited disk space or a similar malfunction.

But, the most important thing is to address the issues so that you can resume the implied update – for doing so you can use the troubleshooting steps from below.
