Just to add-on a bit for potential followup questions, attached is a screenshot from a very stable custom image (W10 21H2) that has been extensively tested, and this is what most people can expect to achieve with enough time and effort (or by using a preset or guide) on W10/W11. For people that don't want to login to view the screenshot, the processes are at 89, threads at 646, handles at 27423, with 1.0 GB memory used, and no CPU or disk activity. This is before drivers and other software gets installed though, so the numbers will quickly rise again if you install too much bloat.
Numbers lower than this are almost always manipulated in some way, riddled with bad tweaks, or are using the previously discussed registry key. You can still lower the resources much further, but you start to get into trade-off territory where you may lose functionality in order to gain resources with additional tweaking from this point forward.
That last paragraph is a generalization though because I could also easily make an image where I got to these same task manager results as the screenshot I posted, but broke 100's of dependencies along the way, resulting in a buggy image. It really depends on the tweaking approach, and I'm not going to elaborate further because it gets to be too much, and in order to better understand all of this people need to just experiment with NTLite and general tweaking to gain the necessary knowledge and experience (or skip all that work and use someone's preset/guide and call it a day).
