I'm stuck with installation of version… I'm stuck with installation of version 10 of UltraDefrag. There is not accessibility in your installation for visually impaired person. I'm furious about this version 10. No problem with version 8 for me but with version 10 there are a lot of problems. With accessibility, with Microsoft Defender. + Eddy François Legrain

Fast and reliable UltraDefrag does everything I want it to do - and more. It is fast, reliable and stable I can only reecommend it.

Is correct. It is going well. The problem is, on the MSFT issue, it should be improved to make it smaller and more usable. In all functions today, they are very good and functional.

Very good software Since it was open source has been the best defragmenter. It's also usable as a portable software. Now it's a commercial software, but nothing has changed.

Absolutely no customer support Absolutely no customer support. Even Fastspring screwed up by sending me a blank URL for the download. None of my many emails to you, Fastspring, and Dimtri were responded too. In my research I discovered that this same scenario happened in 2020 when I first bought the product. It took until three months until November to get the product. I do not plan to upgrade in the future due to these two scenario that left me very angry.
