Virtual Machines (Windows 10, Ubuntu) work more faster UltraDefrag 10 works well on Windows 11 22H2 beta, also with Hyper-V Virtual Machines. I use SSD. Virtual Machines (Windows 10, Ubuntu) work more faster after the defragment of vhdx. I strongly recommend this useful software. Thank you so much for your products!

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

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

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.
