Hiii.... I don't understand why you want to do that... There are not many softwares on your PC... As far as I know there's no way out to remove the programs from launcher... You have written that you do not need them... So, if thats the case why don't you uninstall them... Do uninstall them if you do need them... Just have a look into my profile and you will get many softwares that will be of great use to you... Byyeeeee...
