C:\Windows folder is consuming lot of mysterious space
Solution 1
Did you also uncheck "Hide protected operating system files," also found under Tools, Folder Options, View?
Solution 2
The %windir%\Installer (C:\Windows\Installer in your case) folder is used by Windows Installer to cache MSI files and their associated files, such as MSPs. If you delete the contents of this folder, you may not be able to run repair or uninstall operations on your installed programs without the original program media (CD, download file) present.
Solution 3
Try using a program like TreeSize free on the C:\Windows\Installer folder to see exactly what files/folders are using so much storage space.

What I have?
I have installed Windows Server 2003 with following details:
OS installed in: C drive
Space allocated to C drive: 50GB
RAM: 4GB
Important space consuming software installed: Visual studio 2005 & 2008, Office 2007, MOSS 2007 and SQL Server 2005
C:\Program Files
folder size is around 9GBC:\Documents and Settings
folder size is around 2GBWhat problem am I facing?
When I see properties of
C:\Windows
folder (by right clicking ON the folder), it shows the size as 32GB. But, if I openC:\Windows
folder in Windows Explorer, select all files & folder (including hidden ones) and go to properties dialog, it shows about 7GB!But, my C drive is running out of memory often and I am not able to find what is consuming the rest 25GB of space.
Can anyone help me in cleaning up my C drive?
Thanks in advance!
Update-1
After Raintree' suggestion, I found out that the folder,
C:\WINDOWS\Installer
is consuming around 29GB of space.Is it fine to clear this folder?

deddebme over 14 yearsRemoving the folders and files will cause headache later when you want to uninstall some programs. I suggest you to do an NTFS compression of the whole "Installer" folder.
