Temporary files serve no purpose after use and can be safely removed to speed up your computer, so let’s do exactly that.
Open My Computer.
Select your local drive (normally C:/) and navigate into the Windows folder.
Navigate into a folder called Temp and right-click in file explorer, click Sort By, and then More.
Now add a check to Date Modified.
Right-click in the Temp folder again and now when you Sort By, you’ll see Date Modified as an option. Select it to reorganize the folder.
Now select all the folders that are older than the current date and delete them.
Go to the Recycling Bin and empty it.
1) Uninstall unused programs
New PCs come with a whole load of programs you will never use, and you probably don't even know they exist.
Some programs even run background processes when you load your computer, even though you are not using them.
To remove all these pointless programs, open the Control Panel's Programs and Features page, and have a trawl through the list of installed software. Uninstall those that you do not need, while being careful to leave programs your computer's hardware needs (typically their publisher will be listed as the PC maker's name or as Microsoft)
