For a rollback during setup, the supported first-pass fixes are the same driver and background-process checks used for Windows upgrade failures.
- Back up important data first. Microsoft recommends a robust backup and recovery plan before upgrading.
- Disconnect nonessential hardware: remove external storage, docks, and other peripherals. Leave only keyboard, mouse, and display connected.
- Temporarily uninstall third-party antivirus or security software, then retry the update. These can interfere with setup and rollback.
- Run Windows Update repeatedly until no important updates, hardware updates, or driver updates remain.
- Update third-party drivers from the device or component manufacturer sites, especially chipset, storage, graphics, and firmware-related drivers.
- Check Device Manager:
- Open
devmgmt.msc - Look for devices with a yellow exclamation mark
- For each affected device, use Update Driver Software or Uninstall
- Retry the update after all device errors are cleared
- Open
- Review Event Viewer system logs for driver or hardware-related events around the failed install time and correct any issue found.
- Update BIOS/firmware from HP if a newer version is available for the laptop model.
- If background software is interfering, perform a clean boot and retry the update. This is specifically recommended when setup is terminated by another background process.
- If Windows Update components may be stuck, reset the update cache from an elevated Command Prompt:
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 the update again.
- Check the system drive for file-system errors from an elevated Command Prompt:
chkdsk /f C:
A restart will be required.
- If the failure persists, check whether the device has enough free space. For 0xC1900101-class upgrade failures, Microsoft lists at least 16 GB free for 32-bit OS or 20 GB for 64-bit OS.
Notes on risk:
- Renaming
SoftwareDistributionandcatroot2requires administrator rights and is an advanced troubleshooting step. -
chkdsk /fschedules disk repair and requires a restart. - BIOS updates should be done carefully because interruption can cause system problems.
The log lines shown point most strongly to setup/migration interference from drivers, services, or background software, so the highest-value path is: disconnect peripherals, remove third-party security software, update drivers/BIOS, clear Device Manager errors, then retry in a clean boot state.
