DELL OS recovery

I would like to give credit when due. Have been a DELL desktop/laptop user for many years alongside Thinkpads - both favourites. Over past weeks my Dell Inspiron 15-5510 refused to upgrade past Win 11 Pro 21H2. Hardware is fine, something is wrong with the OS. Started with task manager constantly crashing and had to reboot numerous times daily. Spent a week trying out solutions from the internet but nothing worked for me. Until I could no longer stand it and attempted OS recovery (F12). I have clean installed Win on many machines (including MacBookPros) and I consider myself competant at it. But nothing beat the experience recovering from DELL OS Recovery utility. Truth be told, I have never used any recovery utilities in the past preferring to start from scratch. Recovering was super easy and stress-free. Anyways, this is what I wanted to say. Obviously will buy DELL again.
