May 2020 update error

Just like earlier OS updates, big and small, the latest Windows 10 2004 update had some not-so-pleasant surprises for some users. It failed to install.

In turn, Microsoft put a compatibility hold on some of the affected Windows 10 PCs, just as it usually handles similar situations. That has left some users confused as to why they’re unable to upgrade to an OS they couldn’t wait to explore a few days ago.

Fortunately, Microsoft is at least trying to explain the issue to affected users through a Windows Update banner.

Why you may not install Windows 10 2004 yet

When Microsoft puts a compatibility hold on a device, it stops offering it the update that caused the problem in the first place. That’s what’s happening to users that can’t install the Windows 10 May 2020 update.

According to one Reddit user that experienced the problem, Windows Update is displaying a banner explaining the reason for the compatibility hold.

The notification reads:

The Windows 10 May Update is on its way. We’re offering this update to compatible devices, but your device isn’t quite ready for it. Once the device is ready, you’ll see the update available on this page. There’s nothing you need to do at this time.

Up to nine compatibility holds are right now preventing users from receiving the May 2020 update. However, there may be a temporary workaround for some of the known issues.

PCs with Hypervisor-protected code integrity (HVCI) on are unable to upgrade, for example. Affected users can circumvent the problem by updating their display drivers before trying to install Windows 10 version 2004.

They may also disable HVCI, which would allow the new OS to install. But they’d be compromising kernel-mode code integrity in so doing.

Other driver compatibility problems affecting Windows 10 2004 installation include:

  • Intel iGPU
  • Realtek Bluetooth radios
  • Conexant HDAudio Driver
  • Nvidia display adapters
