For those of you like me that got rid of Iobit System Care I found a similar programme on Giveaway of the day today.Its called Winutilities and is todays giveaway.It has some good reviews and so I downloaded it and tried it seeing as it is free and so far I am fairly pleased with it. 
glary utilities is so good and if you can buy so buy tune up"i have tune up and glary "ccleaner +defraggler are so good too
I’ve used it before if I remember well it is blue as coloured!
But I don’t think it is that good at all I prefer Vit registry cleaner!
Don’t use any registry cleaner that can’t be reversed.
The product in question allows you to create a restore point with it before making any changes.Anyway I looked at the list of registry items and only deleted old known software missing keys etc.
I never read anything I just clean them if there is a problem then I just restore them if after a restart there is no problem then I delete the backup!
