software makes negligable difference to the speed of the PC, they will make some recommendations like uninstall the bloatware and change system settings to remove some of the resource drains and disable some windows system files from loading etc.
But when all said and done it leaves your computer with marginal improvement over previously.
If you want to speed up your computer, by all means remove the bloatware, but the best trick of all is to switch to SSD and install more RAM.
