14 DAY TRIAL // Microsoft rolled out this month’s Windows 10 cumulative updates a few hours ago when the Patch Tuesday cycle officially started, and this time, this release also includes a bunch of known issues.
Given how challenging installing Windows 10 cumulative updates has proved to be in the past, it’s pretty important for everyone to take a look at these known issues, especially because it should help IT pros prepare for deployment and anticipate any problems that might be experienced.
April 2018 Update patch bugs
First and foremost, it’s the Windows 10 April 2018 Update cumulative update released as KB4284835 and bumping OS build number to 17134.112.
There is just one known issue in this update, as Microsoft says that the SMBv1 protocol could be broken down after installing this patch. This is actually an older issue, but appears to be affecting this cumulative update as well.
“Some users running Windows 10 version 1803 may receive an error "An invalid argument was supplied" when accessing files or running programs from a shared folder using the SMBv1 protocol,” Microsoft says, adding that users should enable SMBv2 or SMBv3 while it’s working on a full fix.
Fall Creators Update issues
Windows 10 cumulative update KB4284819, which is specifically released for systems running the Fall Creators Update, comes with two known issues, both of which are currently being worked on at Microsoft, with no temporary solution available.
First, some non-English systems could display a message in English when trying to read scheduled jobs and Device Guard is enabled. The message is “Reading scheduled jobs from file is not supported in this language mode.”
And then, Microsoft says that the same systems could display other strings in English instead of the select language, including Script resource errors and other messages related to operators.
Windows 10 cumulative update KB4284874 for Creators Update comes with no known issues, so experience in this case should be rather flawless. KB4284880 for Anniversary Update (which is no longer supported for Home users) comes with a known issue related to VMs.
“Reliability issues have been observed during the creation of shielded VMs and the required artifacts for their deployment. There are also reliability issues for the Shielding File Wizard with or without the SCVMM interface,” Microsoft says.
One known issue also exists in cumulative update KB4093109 for November Update (version 1511) and in this case, Microsoft recommends updating to the Fall Creators Update. The bug is causing only the latest version of Windows 10 to be offered to systems still running version 1511.
And last but not least, cumulative update KB4284860 for the original Windows 10 RTM version released in July 2015 comes with no bugs and should install correctly.
