Hi, ResteICI
Welcome to Microsoft Community.
We understand your questions about 24H2.
According to your description, at present, the 24H2 update of your computer has been downloaded and entered the * * stage of "installation to be restarted". The system files have been partially modified, but the final configuration has not been completed.Forcibly blocking the update at this time may lead to:-System file residue conflicts, causing startup failure (such as blue screen).-Windows Update database is damaged, and subsequent updates cannot be installed normally.About the limitations of the wushowhide tool:-This tool is suitable for hiding updates that have not been downloaded, and cannot undo updates that have entered the installation stage.-If the downloaded update is forcibly hidden, the system may continue to install after restarting (depending on the update policy).Considering your situation comprehensively, I suggest you do the following:**Option 1: Allow the installation to be completed (recommended)**Operating steps:1. Back up important data (to prevent accidental failure).2. Click "Redémarrer" manually to complete the update.3. After the installation, check the stability of the system. If there is any problem, you can use the rollback function:Go to Settings > System > Restore > Return to the previous version (this option is only reserved for 10 days).This can ensure the integrity of the system and avoid potential conflicts, and you can also go back to the previous version through the functions that come with Windows.For the specific operation of rolling back the system version, you can refer to:Go back to the previous version of Windows - Microsoft Support**Option 2: Forced removal of updates and delayed installation.**The risk of doing this is that the system files may be inconsistent, and sfc /scannow and dism repair need to be run later, and Windows may re-detect and force push 24H2 (hidden by regular maintenance).If you must stop 24H2 and are willing to take certain risks, you can try this method.Operating steps:1. Terminate the update process:net stop wuauservnet stop bits2. Clear the downloaded update file:del /f /s /q %windir%\SoftwareDistribution\Download*3. Hide 24H2 update:Use wushowhide, and choose to hide "Windows 11, version 24H2" after running.4. Restart the system and resume the update service:net start wuauservnet start bitsSince we are only support personnel, not Microsoft engineers and employees, we suggest that you can press Windows+F to give your questions and comments to Microsoft officials about the problems that appear in the new version of Windows, or if you have any comments on 24H2. Only when you give your comments back will the development team know about the problems.After submission, please share the feedback link here, because this will allow others on the forum (including me) to vote for your submission. More votes will increase the attention and priority of the development team. Thank you for your understanding!If you need more help, please feel free to contact us.
