Today is the second Tuesday of the month, meaning that it"s time for Microsoft to release cumulative updates for all versions of Windows 10. Being that the Windows 10 April 2018 Update was first made available last week, this also marks the first patch for the newest feature update.
Users of Windows 10 version 1803 will see KB4103721, which brings the build number to 17134.48. It can be manually downloaded here, and contains the following fixes:
Addresses an issue with the April 2018 Windows Servicing update that causes App-V Scripts (User Scripts) to stop working.

It contains the following known issue:
| Symptom | Workaround |
|---|---|
| After installing the March 13, 2018, or later cumulative update for Windows 10, version 1607, only the most-recent Windows 10 feature update is returned as applicable. This prevents the deployment of previously released feature updates using ConfigMgr (current branch) and Windows 10 servicing plans. | Decline all feature updates on the WSUS server(s) except for the one that you want to deploy using ConfigMgr. Run another software-update scan cycle from the ConfigMgr control panel or wait until the client devices perform their next scan. Microsoft is working on a resolution and will provide an update in an upcoming release. |

Typically, we"d tell you that if you use Windows Update, the service will automatically download the patch that corresponds to your version of Windows, but that"s not the case anymore. Anyone checking for updates will get 1803, so if you"re not an early adopter, you"ll want to install these updates manually or wait for them to roll out automatically.
