How to stop a Windows upgrade in progress?
If the Windows upgrade has begun, whether it can be stopped depends on the current stage. 1. If it is in the download stage, you can try to end the "WindowsUpdate" or "BITS" process through the Task Manager and pause the update in the settings; 2. If the installation has started but has not restarted, you can uninstall the latest update through the control panel; 3. If the upgrade enters deep installation, forcibly interrupted may cause system damage, so it is recommended to avoid it; 4. To prevent future automatic upgrades, you can use the Group Policy Editor, set it to traffic billing mode, or pause the update function. Overall, the risk of stopping mid-time upgrades is high, and planned delays should be preferred to ensure system stability.
