User Case

“I build this PC a couple of years ago, and accidentally installed Windows 11 on to hard drive, rather than my SSD. I only learned about this recently, as my system has been frequently slowing to a crawl, my C: disk getting stuck at 100% usage basically rendering my system unusable for up to half a minute at times. It's extremely frustrating. Now, I want to migrate Windows 11 to SSD. Is there a way to do this without installing the system? Thanks a lot.”
