According to Microsoft's documentation an installation of XP SP3 peaks at 1.5GB
However, in my case the actual size of C:\WINDOWS
is 12 GB, amounting to a ten-fold difference.
Neither CCleaner nor Disk Cleanup were able to find anything significant but obviously something must be hiding somewhere.
A quick scan with WinDirStat revealed the following:
C:\WINDOWS\Installer 4.3 GB
C:\WINDOWS\system32 1.7 GB
C:\WINDOWS\$hf_mig$ 1.4 GB
C:\WINDOWS\assembly 1.3 GB
C:\WINDOWS\Microsoft.NET 780 MB
C:\WINDOWS\ServicePackFiles 588 MB
C:\WINDOWS\SoftwareDistribution 485 MB
Any tools or suggestions for wiping at least some of it?
