Earlier this week, Microsoft began rolling out Windows 10 cumulative updates to all supported version of the operating system, as part of its Patch Tuesday cycle. While Windows 10 devices after installing the update seems to be functioning properly but it looks like the latest cumulative release for Windows 10 Fall Creators Update isn’t installing for everyone.
Many users on the Microsoft’s Community forum reports that they are getting errors when installing Windows 10 KB4054517. Basically, Windows 10 KB4054517 is not installing on all devices. For those wondering, this cumulative update advances the system to Windows 10 Build 16299.125.
“Windows 10 KB4054517 failed with an error code of 0x80070643. The only thing we’ve discovered so far is that this machine will not display our other 3 PC’s on the network when we select “Network” in File Explorer. But all three other PC’s can “see” and access this PC no problem. And we ran a batch backup job on the affected PC and it was able to copy files from all three other PC’s. So it’s just a display problem in File Explorer -> Network,” a user explains on the forum.
It appears that this is a widespread issue affecting all Windows 10 PCs including the flagship ones. Windows 10 cumulative update KB4054517 fails to install with error code 0x80070643. The users have explained that the common workaround Windows Update troubleshooter is not working.
Microsoft hasn’t acknowledged the bug just yet but since it is a widespread issue, we can assume that Microsoft is already working on a fix.
