Potential Dangers of Cleaning Registry in Windows 11
- Cleaning registry in Windows 11 that are still in use or linked to system components can cause system instability, errors, or even prevent Windows from booting properly.
- If some residual registry entries are still needed by other programs or system features, deleting them can cause those apps to malfunction or crash.

- Manual editing or automated registry cleaning tools that are overly aggressive can corrupt the registry, leading to system errors or the infamous "blue screen" (BSOD).
- Registry cleaners often can't identify all orphaned entries accurately, sometimes leaving behind unnecessary data or removing entries that should stay.
