Hi Dilip Manohar,
Thanks for reaching out to Microsoft Q&A Forum. I understand the latest Windows updates do not install successfully and your PC keeps going through a remove and reinstall loop.
Please make sure you already tried the Q&A Assist steps. In addition, please try the following.
Which update KB number keeps failing in your update history, and what error code is shown for the failed install? Is this a personal Windows 11 PC, or is it managed by an organization (work/school device policies)?
In the meantime, you can try these steps:
1, Disconnect non-essential peripherals and try updating again
- Unplug any USB drives, memory cards, printers, and docking stations
- Restart the PC and try Windows Update again
2, Run the Windows Update troubleshooter from Get Help
- Open Get Help and run the Windows Update troubleshooter, then restart and retry Windows Update
3, Use Fix problems using Windows Update to repair the current Windows installation
- Open Settings, then System, then Recovery
- Under Fix problems using Windows Update, select Reinstall now, keep the device connected to power and internet, then restart and check Windows Update again
4, Install the failing update manually using the Microsoft Update Catalog
- Identify the failing KB in your update history
- Download and install the same KB from the Microsoft Update Catalog, then restart and re-check Windows Update Disclaimer: This link does not support your language. Please use a browser translation tool to engage with the content.
5, If the loop continues, do a repair install that keeps apps and files
- Use the Windows 11 in-place repair option that preserves apps and files, then retry Windows Update
