They suggest using totalsystemcare in the video, but you can opt for CCleaner to clean the registry since totalsystemcare often overstates its role and the issues it reports. I tested it about ten years ago, and it consistently uncovered new problems—so much so that even a 16-year-old could spot something odd. I stopped using it, and surprisingly, my computers still function properly. Edit: After reviewing the video with over 600 dislikes and just 200 likes, it seems the content might not be as trustworthy as claimed.
Uncertain about the corruption, I've observed the background now appears as solid black. Also, the welcome screen lacks the spinning circular dots you were expecting.
A deep black screen often indicates a copied Windows installation, though a legitimate copy may need reactivation and could require a fresh setup.
