If you’re trying to install Windows 10 May 2019 Update (version
1903) on a device running incompatible drivers and software,
there’s a chance that the update won’t show up and Update
Assistant will render a warning of incompatible software.
The upgrade block could be placed on some devices due to
compatibility problems. This could be associated with certain
Intel driver versions, outdated anti-cheat software and other
services that may have the potential to cause problems. As per
multiple Reddit discussions
and Twitter threads, some users are unable to install Windows
10 May 2019 Update on their devices.
Microsoft has already acknowledged a bug with certain Intel
driver versions that causes brightness problems. Microsoft has
placed an upgrade block on such devices and a fix is being
“After updating to Window 10, version 1903, brightness settings
may sometime appear as if changes applied took effect, yet the
actual display brightness doesn’t change,” Microsoft explains
in a support document.
“To safeguard your update experience, we have applied a
compatibility hold on devices with certain Intel drivers from
being offered Windows 10, version 1903, until this issue
is resolved,” the company added.
Unfortunately, Update Assistant doesn’t specify the problem
with Windows 10 May 2019 Update. It only states that the PC has
a driver or a service that isn’t ready for Windows 10 version
1903 and the update will be offered once the issue is resolved.
In a thread, a Reddit
user explains that Media Creation Tool may also block the
update if incompatible driver or service is running.
If the update is blocked on your device, you should install the
latest versions of software such as Battleye and drivers or
wait until a fix is available. You can also clean install a
copy of Windows 10 May 2019 Update with Media Creation Tool or
directly through ISO files.
