Windows Updates will not complete on new HP Omnibook laptop

This pattern matches a known Windows Update failure path: the update starts, the device restarts, progress reaches around 30%, then the system appears stuck and later rolls the update back.

Try these steps in order:

1. Wait once before forcing power off A temporary black screen during update can last several minutes on some systems. If the HP logo remains with no progress for an extended period and the update does not recover, continue with the next steps.
2. Repair Windows system files Open Command Prompt as administrator, then run:

      DISM.exe /Online /Cleanup-image /Restorehealth
      sfc /scannow
   

   Expected result: DISM should report that the restore operation completed successfully, and sfc should reach 100%.
3. Reset Windows Update components Open Command Prompt as administrator and run these commands one at a time:

      net stop bits
      net stop wuauserv
      ren %systemroot%\softwaredistribution softwaredistribution.bak
      ren %systemroot%\system32\catroot2 catroot2.bak
      net start bits
      net start wuauserv
   

   Then restart the PC and try Start > Settings > Windows Update > Check for updates again. Warning: Renaming these folders resets the local Windows Update cache. This is a standard troubleshooting step, but pending update history in the cache may be cleared.
4. Check for third-party driver updates On a new HP laptop, install any newer hardware drivers from the manufacturer, then try Windows Update again. Driver conflicts can block update completion.
5. Make sure there is enough free space Windows requires at least 16 GB free for a 32-bit OS or 20 GB for a 64-bit OS to upgrade.
6. Try a clean restart A clean restart starts Windows with a minimal set of drivers and startup programs, which can help if background software is interfering with the update.
7. If the device becomes stuck during startup again Force Windows into recovery by interrupting startup multiple times, then use Startup Repair or System Restore from the recovery options.
8. If the issue is specifically “updates install, restart, then get rolled back” There is a documented case where updates are uninstalled after restart because the Trusted Installer service does not finish within the default timeout. The workaround is to change the registry value: HKLM\System\CurrentControlSet\Services\TrustedInstaller\BlockTimeIncrement to 2a30 (Hexadecimal), which sets the timeout to three hours, then restart and apply the update again. Warning: Editing the registry is a high-risk step. Incorrect changes can cause startup or servicing problems. Use this only if the rollback behavior continues after the safer steps above.

If the laptop is brand new and repeatedly fails only during the restart/install phase, the most practical order is: DISM/SFC, reset update folders, HP driver updates, then clean restart. If it still rolls back, use Startup Repair/System Restore, and only then consider the TrustedInstaller timeout workaround.
