Yes, a lot of great tools, 2nd on my list is process monitor. It lets you know what sys calls were performed by any process, same as ptrace I believe. Super use

Yes, a lot of great tools, 2nd on my list is process monitor. It lets you know what sys calls were performed by any process, same as ptrace I believe. Super useful to debug a 3rd party app, for instance one that doesn't even start, looking for a file or reg key at different places, failing and exiting early. It allows one to fix it even if there are no errors or logs at all.
