What our clients say?

(4.5 out of 5)


I tested it on my old laptop that took nearly 5 minutes to boot and login and start using… After an overnight optimization, I restarted my computer to test it out and boot up was nearly instantanious. I logged in, and everything popped up like, if you blinked, you missed it… No one should be without this software. Stellar job, UltraDefrag developers!


Excellent and reliable tool for many years and across many versions of Windows… I’ve used and beta tested hundreds of software products and this is one of those few products that filter past all other worthy tools and become permanent keepers. It does what it’s supposed to do, without making too much noise or wasting my time and it does it extremely well!


Yes the first time you run this program, it takes a long time but it is worth it… I have used many, many defrag programs and this one can make an old computer run faster than it was new. The boot time process really speeds up your computer starting up and shutting down. I have never had a problem with UltraDefrag and have never seen another program do a more thorough job.
