Have installed Glary utilities on both my XP PCs and it is a treat to use.

For me the 4 best features are the:
1) One Click Optimise/Fix when I don't have time to do anything else,
2)Process Manager, which has allowed me to finally get rid of an old version of mcafee internet suite which I couldn't delete any other way and which continued to hog resources despite umpteen previous attempted deletions,
3)Memory Optimiser, which will sit in the system tray only using minimal resources compared with other optimisers which are more trouble than they are worth. and
3)Windows Utilities EXTRA features which allows a Disk Check without having to reboot which is a real timesaver and wear and tear saver on the hard drive. It also give quick access to disk defrag.

Even better it is light on resouce use compared to other resource hogging costly programs and the basic version is free. It is often said about software: "pick any 2 of good easy and cheap", well this is good easy and FREE! It doesn't get any better except for the pro version which I will buy when finances allow.

Thanks for a great program, this is the best and easiest utility I have ever used.
