Here's a few old-school tools for patching memory either in RAM or patching a binary file. I'll also drop some disassemblers here, although with the ever-present cloud push much of the perpetual licensing model has become obsolete. Nevertheless, there's still many niche use cases for these hard-to-find tools, and they ARE NOT MALWARE!! They may be flagged as hack/crack tools, because that's what they are !! lol.
I'll start with dUP2, a patching tool that creates an .exe that patches a locked piece of software to an unlocked piece of software, given you have access to that unlocked piece. (I.E. school GIS software, work photo editor, etc)
The next tool is called Bloatynosy, and it's for Windows 11. This tool not only debloats new PCs but can add a whole slew of software and tools. There's not much that's not included in there that any PC will need or use.
