I found a video claiming that running "irm christitus.com/win | iex" would debloat my Windows PC, so I executed it without really thinking about the risks. Is the script generally safe, and what should I do now? It also removed Clock, OneDrive, and Paint, so I'm wondering whether that is a serious problem.

Removing Clock, OneDrive, and Paint is usually not a sign that Windows has been damaged; those are optional built-in apps and can generally be reinstalled through the Microsoft Store or Windows features. Check the script’s undo or restore options, and create a restore point before making further changes.
Don’t assume a script is safe just because it is popular. Review the actual PowerShell source, check what commands it runs, and compare it with established open-source debloating projects before choosing one. If you’re concerned that something malicious ran, scan the system with Windows Security and review recent changes.
The script is widely used for Windows cleanup, but you should never pipe downloaded PowerShell code straight into execution without reviewing and understanding it first. Debloating tools can remove built-in apps and change system settings, so read the source and documentation before using anything similar.

Understood. It also removed Clock, OneDrive, and Paint—should I be worried about that?
