Chemo

I want to bring my computer to the brink of death using an overdose of chemo, only to have it maybe survive and be a normal computer

Chemo rids your Windows 10 machine of the pre-installed junk you don't want. We can't guarantee that it will stay gone forever, but you may always come back for another round of treatment, if you desire.

⚠️ Warning ⚠️

Chemo can and will eat your lunch. Before using this tool, please make a snapshot, system restore point, or other backup of some kind.

You probably don't want to use Chemo on your primary machine. Unless you are comfortable with performing a fresh installation of Windows or restoring from a backup image, don't use this tool!

Chemo is currently in a pre-alpha state. Contributions and feedback are greatly appreciated!
