Putting "reviews on pc decrapifier" in a Google search brought up quite a bit of information on this programme from various sources. It would appear that it cleans bloatware and internet files, and that's about it, with a possible rating of 5 out of 10.
Perhaps on those results, not the best programme to have, possibly bloating your computer even further?.
Uninstall it if you have finished or don't intend using it (it's one that you have downloaded and installed or they put it on at the shop where you had laptop restored). More info on the free program PC Decrapifier click here
