You could start by downloading the free version of Revo-Uninstaller. It will show you every single program you have installed. *Selecting Chrome (for Example) and select Uninstall. Select deep scan, Revo will create a Restore point and then run Chromes own Uninstaller, follow the instructions to remove Chrome as normal.I will have it done next week and let you know.
You could be a genius using plain language like that.
Back in Revo the magic is what happens when you click next, Revo scans your System for any left over directory's, files, and hidden Registry settings. You will be surprised by the amount of **crap left over, it is entirely safe to select ALL and Delete. Select next again if the option is available and do the same. You may get a pop up saying some items will be removed after a restart, remove any other programs (like ***AVG, etc, etc) and then do your restart.
*I would suggest leaving anything with your Laptop Manufacturers name or anything Microsoft alone.
**the crap is what programs use to either reload itself on a reboot, or save your last known settings.
***You may need to use windows task manager and 'end task' to stop the program running first.
