Microsoft has halted distribution of Windows 10 April 2018 Update for owners of systems with specific Intel SSDs, the combo of the operating system update and the Intel SSDs can result in a boot loop.
-- Microsoft --
Microsoft learned that devices with certain Intel SSDs repeatedly crashed during the installation of the update reports myce; other devices continuously restarted and got into a boot loop after which the systems became unusable. Therefore, the software giant decided to stop distributing the updates to affected systems. Microsoft does not list which exact Intel SSDs suffer from the issues. Currently, there is no patch or workaround available for the issue, it’s expected that after Microsoft has found the root of the problem, it will release an update and make the Windows 10 April 2018 Update available to owners of the affected systems again.
MS mentioned 'certain' Intel SSDs, but does not name them specifically by model. Windows 10 users with an Intel SSD, who already installed the Windows 10 April 2018 Update, are advised to return to an earlier version of their operating system. This can be done by pressing F8 during boot-time. For now, owners of those systems won’t get the update automatically and can’t start the update manually.
