#4 – Remove Unwanted Software
Problem: Having unnecessary software on your computer not only takes up hard drive space, but some of the software can run in the background taking up valuable RAM and processing power.
Solution: Within the Programs / Programs and Features section of your Windows Control Panel, select the programmes you want to remove from the list and click on remove. You can also do this from within the Tools > Uninstall section of CCleaner. Run this check every 3 – 6 months, depending on how much new software you install (you might also want to remove non-essential items from your desktop too).
