Quote:In an update to the Windows 10 Health Dashboard, Microsoft has confirmed that they are working on a fix for the 0x80073701 error that users are receiving when installing new v1903 updates.
 
After the August 2019 Patch Tuesday updates were released, users started reporting that they were receiving errors when trying to install Windows 10 version 1903 cumulative updates.
 
Users would install the update, it would get to 100%, and then display an error code. The most common error codes seen in the reports are 0x80073701, 0x800f0982, 0x800f081f, 0x800f0845, and 0x8024200D.

In an update to the Windows 10 Health Dashboard, Microsoft has acknowledged that this issue is affecting both Windows 10 and Windows server version 1903. They have also stated that they are "working on a resolution and will provide an update in an upcoming release."

"Installation of updates may fail and you may receive the error message, "Updates Failed, There were problems installing some updates, but we'll try again later" or "Error 0x80073701" on the Windows Update dialog or within Update history."

While most user reports indicate that the problem started on August 13th, Microsoft is stating that the issue actually popped up when the May 29, 2019 - KB4497935 cumulative update was released.
It is not known if any future fix will also resolve other error codes that users are receiving.
