Not sure, but they do have a free version that does not automate any of its features or remind you to update (or auto update, can not remember which it does). I would assume this giveaway just loses the Pro features and you are set back to the free version’s features.
I love Glary Utils, but their annual fees to stay with Pro are an added expense I simply do not need. Besides, the free version is just as good for doing things manually, which I prefer.
Thanks Ashraf, for doing these giveaways.
