So I'll skip the sermon! Though next time you do bring your MiKTeX up-to-date, 
use the net installer to download a *complete* MiKTeX repository. This has two 
benefits:

1) Repeatability - any machine you install on using your local repository will 
behave in the same way; for perfectly understandable reasons, the quality 
assurance of MiKTeX updates is, in my opinion, low (if I had £1 for every time 
someone posts on the MiKTeX list "I ran the updater and now everything's 
broken" followed by one from an expert/maintainer "that'll be fixed in the next 
update tomorrow"...)
2) Longevity - you can carry on using that version after the mirrors have 
stopped supporting it (if you're very organised, you can download the complete 
repository on the last day of its availability and guarantee having the last 
version)

It's not about working fine - it's about using unsupported systems connected to 
the Internet which may contain vulnerability. MiKTeX 2.6 contains a security 
vulnerability (I know because I reported it), albeit an 
unlikely-to-be-exploited one. It was partially fixed in MiKTeX 2.8 (and 
possibly completely dealt with in MiKTeX 2.9, I haven't checked).

Have you tried Virtual Box (www.virtualbox.org)? Very easy to install and if 
you have your Windows CD/DVD to hand you can trivially activate the second 
installation (IIRC before Windows 8, it's ambiguous whether it's technically OK 
to install the virtual instance with just one licence - but you can always 
download a 180 day demo ISO for Windows 2012 from the Microsoft website if that 
worries you).

Having installed Windows, take a snapshot of the virtual machine. Now, every 
time you want to play with a new version, start the virtual machine, play with 
it to your heart's content and afterwards restore the snapshot (which will 
erase everything you did). It's a brilliant sandbox for trying out new 
versions, etc. without *any* risk of damaging your important main installation 
(and believe me, given the pages of instructions I have on installing and 
configuring TeX on each machine I use, I appreciate exactly what you mean about 
the time investment!).
