This is a personal experience thing, but I really do not like registry cleaners.Judging by your post yesterday you had other problems with this laptop which you may or may not have solved. These registry cleaners can exacerbate problems rather than help. I must admit I have used Winaso in the past the other on (CleAN uP) I have never heard of or can find out anything about.
You could try a repair install which will hopefully replace any corrupted files.I personally do not like the repair option. Or you could copy everything from the HDD and perform a clean install.
You mentioned in your other post that you thought there might be a problem with the HDD have you tried this.HDD health. Useful in determining the health of your hard-drives
