I regularly backup my whole system with Acronis True Image every weekend. After cleaning the 34,423 invalid paths in the registry as reported in my Post 331, I just found the size of the backup has also reduced from 279GB to 176GB. Double checked and confirmed my system is intact.

Not sure why. But, isn’t it a good thing to maintain a clean and error-free system while at the same time saves 100GB disk space ?
