How can I reduce the amount of hard drive space Windows 7 uses? I've got my Win7 cramped into a 10GB virtual machine, and with Office installed, I’m running out of space. The short answer 'use a bigger virtual HD' is not working out for me. The host (Mac) is also pretty low on space, and if we can save space, why not do so?
nLite/vLite do only seem to be available for WinXP and Vista. I've already obviously disabled the trashcan. I've disabled hibernate to avoid the use of a 4GB hibernate.sys file. Any other tips? I'm primarily interested in post-install methods, but if we can save enough space during the installation, it will justify a fresh installation.
EDIT: this question is allmost a duplicate of what stuff can safely be deleted/uninstalled from a fresh windows-7 install. My question is more wide, because I would like to see more tips like deleting cached/temp update files.
