Two weeks ago, we reported that the major update Windows 10 April Update was experiencing serious problems with some SDDs.
The impacted hardware was computers with Intel 600p or 6000p series SSDs or Toshiba XG4, XG5, or BG3 SSDs.
For the machines concerned, Windows 10 April Update did not install correctly and the user was starting up with a machine blocked on the UEFI screen. The only way to recover an operational machine is to reinstall the previous version of Windows 10.
Microsoft quickly recognized the problem and suspended the deployment of Windows 10 April Update on these devices
Microsoft has corrected these issues. Users who have stopped the Windows Update service on their machines to avoid problems, can re-enable it and let their Windows 10 update.
