NTLite users can create or use a preset, or list of component removals, in order to debloat a Windows image. Some removals are available to all users, others require an activated license to perform.I am very new to this. And looking for a Script that will remove all the garbage that is not needed. And all telemetry. And I will be using it on Windows 10 Pro 20H2. And like I said I'm new to this and do not know what I am doing.
There are no "scripts" in this process. If you're looking for generic W10 debloat scripts, there are several projects out there and they mostly run on an installed system. A few will debloat an image only as far as to remove Windows default apps, but rarely anything beyond that.
Most of the removals referred in this thread do require a licensed copy of NTLite. But you're welcome to install NTLite and try whatever removals and settings are unlocked in the free edition.
