Alright i just checked with fsutil behavior query disabledeletenotify in cmd and TRIM is activated. My ssd is already windows optimized.
It should be fine once i reinstall my complete system, hopefully.
No matter what it was worth giving it a try but personally i'm not sure if i should recommend that feature to other users.
Again thx for the super fast and helpfull replies.
Small Update: after about 1 month the Boot is as fast as it was before.
