[Solved] Difference in space usage between W7 Home Premium & Ultimate Hi There, Can somebody please explain why Windows 7 Home Premium ( on my laptop ) is taking up more space than the Ultimate version on my desktop ? Both systems are installed, along with the application software, in the C partition of 30 GB with W7HP taking up nearly 4GB more then Ultimate. I have more applications, taking up more space, under Ultimate. Both systems have 2GB RAM, all System Restore points have been deleted, Hibernate is on and I have run both Disk Cleanup ( as Administrator ) and CCleaner to clear out any junk. It’s no real problem but it is annoying me, I would have thought that the Ultimate version would take up more space. Thanks for any info.
