Fix Windows 10 June update

Follow these steps to troubleshoot a Windows 10 freeze at or just after login following a June update:

1. Check for known black/freezing screen issues from recent updates
   Some cumulative updates have known issues where devices may start up to a black screen or appear frozen on first logon after installing updates. These issues are resolved by installing the follow‑up fixes that Microsoft released later.
   If the system becomes usable after waiting several minutes, sign in and run Windows Update again to install any newer cumulative updates that supersede the June update. For example, issues where “a small number of devices may startup to a black screen during the first logon after installing updates” were later fixed by follow‑up updates such as KB4520062.
2. If the system appears hung during update processing and then rolls back
   If the device shows messages like “Working on updates… Don’t turn off your computer” for a long time and then reverts changes, Windows Update may be timing out while finalizing updates. In that case:
   1. Boot into Windows (or Safe Mode with Networking if normal boot is unstable).
   2. Open regedit and navigate to:
      HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\TrustedInstaller
   3. Grant Administrators Full Control on the TrustedInstaller key.
   4. Edit the BlockTimeIncrement value and set it to 2a30 (hexadecimal), which extends the TrustedInstaller shutdown timeout to about three hours.
   5. Restart the PC and let Windows reapply the pending update.
      This prevents the installer from timing out and rolling back changes, which can otherwise leave the system unstable after login.
3. If the system freezes a few minutes after startup
   If login works but the PC consistently freezes a few minutes after boot (for example, around 5 minutes) following an update, a scheduled task may be involved. One reported case of Windows 10 freezing a few minutes after startup was traced to the scheduled task:
   Task Scheduler → Task Scheduler Library → Microsoft → Windows → PI → Secure-Boot-Update
   Disabling this task stopped the freezes in that scenario. To try this workaround:
   1. Boot into Windows (or Safe Mode if needed).
   2. Open Task Scheduler.
   3. Browse to Microsoft → Windows → PI.
   4. Locate Secure-Boot-Update, right‑click, and choose Disable.
   5. Restart and test whether the freezes at login/shortly after login stop.
      This is a workaround; once Microsoft releases a specific fix, re‑enable the task and install the updated patches.
4. If the device is stuck in a failed update loop at first boot or after update
   On some OEM or new devices, a failed update can prevent normal startup. In those cases, use Windows Recovery Environment (WinRE) to roll back or repair:
   1. Power on the device and, as soon as the Windows or OEM logo appears, hold the power button to force shutdown. Repeat this 3 times until Automatic Repair appears.
   2. Select Advanced options → Troubleshoot.
   3. Try System Restore first to revert to a restore point from before the June update.
   4. If System Restore is unavailable or fails, use Startup Repair.
   5. If the system still cannot boot stably, use Reset this PC → Keep my files (local reinstall) to repair Windows while preserving personal data.
5. If freezes persist after these steps
   If the system still freezes at or shortly after login even after installing follow‑up cumulative updates, adjusting the TrustedInstaller timeout, and testing the Secure-Boot-Update task workaround, collect logs and contact support. For Windows client update issues, Microsoft recommends gathering data using the TSS tool described in the Windows client troubleshooting documentation and then engaging support.
