It appears Auslogics are currently offering their BoostSpeed 5 software for FREE.

I have some reservations over whether this is the full (unlimited) version or not. The offer on the MajorGeeks site is for an S.E. version; S.E. standing for special edition, which generally means it would be feature limited. Another link from Auslogics however states the offer is for the FULL version.

Here is the link to the offer at MajorGeeks store: http://store.majorgeeks.com/p13357-ausl ... speed_5_se
Here is a link to the offer from Auslogics (which also appears to be connected to the MajorGeeks download): http://www.auslogics.com/en/cpages/spec ... on=getcode

It could be that the S.E. (Special Edition) merely denotes that the software is being offered free only via MajorGeeks.....and it may well be the FULL version.

Anyway, I'll leave it with you to decide.
