You never know, but you could be wasting about 300 GB of disk space upwards by temp files squatting on your machine. Hit the Windows Key, type in "temp" and invoke the cleanup from Windows Explorer.
Another way of tackling this is to right-click your Windows installation drive (say it is C: drive), go to General and select Disk Cleanup.
The latter technique will help you eliminate "general" temporary files as well as more "specialized" temporary files such as thumbnails, downloaded files, Delivery Optimisation files and DirectX Shader Cache files (files created by the graphics system to speed up load time).
