Windows 7 Desktop PC 500GB Hard drive space being used.

  Cumano 00:16 08 Dec 2014

For over two weeks the HD of my PC has used 40gb of space. Considering that I have not done any downloads other than updates for Windows O.S. and Adobe Apps. I don't know what is using it. Can anyone help ?

It may be backups taking up the space. Run WinDirStat to see what's taking up the space.

From Cumano, to Onthelimit1, I've tried to download WinDirStat.exe from 3 download sites, but, for some reason it just will not download. Thank you for your help.

Try Treesize (free) see:


I would put my money on hidden restore points. For a start you can see how many there are and removin all but the latest 2 by using CCleaner (I assume you use it to clean temp internet files?) Here is a link if you do not have it (The free version is fine) :


In CCleaner, Tools, System restore - select and remove the older ones.

You can set a limit on the % space allocated to system restore - come back if you need further info.

From Cumano to John Bunyan, I downloaded CCleaner and used it as you suggested. I have now regained 31gb of HD space, but I can't find out where to set System Restore limit. Thank You for help, it's very much appreciated.

Assuming your HDD is not partitioned, I would set the amount of space allocated to system restore to about 12%. To do so, Click on start; click on computer; right click on Properties; click on System protection; click on tab "System Protection"; click on -Highlight - C: drive; click on configure; in next screen tick the top option "Restore system settings" ; further down there is a slider where you can set the %.(it will tell you the current usage). For info my current usage is 9% with a limit of 12%. I have about 3 or 4 restore points. Hope it works ok, do tick if so.

PS in another thread you asked about creating a restore point; Windows does this automatically from time to time and at update times. I only do a manual restore point before installing a programme I may wish to uninstall quickly, or perhaps after a clean up after a malware or similar attack, as there is a danger of an unnoticed "infection" being kept in an automatic restore point.
