Windows Slimmer

Hi

I am a bit interested in above mentioned softwares compact feature. When running it it says that it can compress W10 with 1.9gb, windows inbuilt feature says only 0.5gb when running it. So how can your program compress so much more, 1.4gb more, that is a lot. Very!

I hope i will get a really detailed, extensive answer to my question, now when i have taken the trouble to download and install "Boostspeed" to get an answer.

So, how can your software compress so much more then Windows inbuilt feature? Why the difference? What does it really do?

Hi, what are the cons of compressing the OS ?
Is it safe?

After scanning for old windows libraries and initializing the cleaning process. It says process completed but no files are cleaned. Still 2.7 Gig installed on rescan and same problem on re-cleaning. What to do? Thanks
Sorry, I couldn't find a catagory for Windows Slimmer questions
