After reading these comments, I thought I would add mine. I first started using Glary Utilities several, several years ago. Had no problems and purchased a life-time license. Yes, I am still using this software and have had no issues including using task manager. I have a Win10 Pro which has been upgraded to Win11 Pro. I also use Kerish Dr. (which is an amazing software even by itself). As far as the comment about the task manager with Glary installed, I have to say that I still don’t have an issue with the task manager and believe it had to be another issue causing that problem.
