Hi Vanitas, thanks for your question. I'm Graeme, a Microsoft Community expert and fellow user.
Firstly, the latest version of Windows 10 is 1809, so if you can, try updating using the steps outlined in this Microsoft Support article:
https://support.microsoft.com/en-au/help/402868...
If that doesn't work, you could try the Windows Update Troubleshooter. Here's an article that'll show you how to use it:

If your Windows Update still doesn't work, you could try resetting the Windows Update components manually. Here's a link to the instructions:

Please let me know how you go with these steps and if you need further support I'll see what else we can try! Thanks!
