I needed more space on my laptop’s hard drive so I did two things (after I deleted all temporary files and emptied the Recyle Bin).
Reduce the amount of space reserved for the Recycle Bin
The first thing I did was to reduce the amount of space that was reserved for the Recycle Bin. Right-click the Recycle Bin icon on your Desktop, click Properties. On the Global tab, move the slider to 1% (the Recycle Bin will still have over 200MB reserved).
Delete all but the last System Restore files
Next, I deleted all but the last System Restore files. Right-click on the Start button, click Explore. Find your C: drive and right-click on it, then click Properties.
On the General tab, click Disk Cleanup. Let the Disk Cleanup do its thing. When it’s finished, View Files and decide if you want to delete anything.
Stay in this dialog box.
To delete all but the last restore point, click the More Options tab. In the System Restore section, click Clean up, Yes to delete, OK, Yes.
It’ll take some time for it to finish. Click OK when done, then go back to Properties to see the change.
These two simple steps freed up over 5GBs of space on my laptop. Now I won’t have to buy a new one.
Update: Reinstalled Windows and laptop is like new. This was the biggest improvement of all!
