Creating portable applications for a cleaner system

I'm pretty new to portable applications and came across software such as cameyo and thinapp that uses virtualization but in order to create a portable application it requires the use of a virtual machine with a fresh operating system install to capture changes before and after each software that is being made portable.

Seems like a lot of hassle and even more so to keep those applications up to date as would require creating a new portable app version. I only want to use it with software that I rarely use like the list below. Is their a more simple way to better managing installed software ?

Drive partitioning software
Extended registry search software
File size explorer like treesize
Advance uninstaller software like revo uninstaller
Google Earth
Speed Fan / CPU-Z / Everest / belarc advisor / hd tune

This won't help much, but I know for a fact that CPU-Z doesn't have to be installed. Here's the standalone "version" (it's not really a different version though):

Direct download of the 32-bit version in a .ZIP file: CPUID - System & hardware benchmark, monitoring, reporting

I just wanted to point that out because I didn't want to go away from this thread knowing that I could have contributed something.

Take a trip to PortableApps.com. It'll be cloud nine, if not heavenly. Down to earth, a real smorgasbord.

I found portableapps didn't have that many applications, however I found a website similar called thinstallsoft which seems to create a lot of portable versions of applications

Since you have Factory OEM the tools and methods which work best with it based on countless thousands of installs we've helped with here are in Clean Reinstall - Factory OEM Windows 7.

If you still have the corrupt factory preinstall I would treat yourself to Win7 native performance by doing the reinstall, taking your time to get it perfect, then capture an image and never have to do it again.
