Operating Systems

[ezE]

sorry if this has already been answered but I have limited research time.
I'm looking for an operating system. I like win7 as its stable, familiar, and fast.
1) what would win8 have that win7 doesnt, that I would benefit from?
2) How is win8 on the WGA validation system? What is the risk now days?
I found one of the newest releases:

Windows 8 1 AIO 24in1 with Update x64 en-US Jun2014

3) What are all these new acronyms? What do I need to know?

Microsoft Diagnostics and Recovery Toolset (DaRT) 8.1
Added Info folder to Windows Setup dir to annoy credit theives
murphy78 diskpart/apply script v1.2.4

Features:
-NetFx 4.5.2
-Windows 8.1 with Update MSDN/ESD download
-Highly compressed ESD format.
-DaRT 8.1 integrated into boot.wim and winre.wim recovery options.
-UEFI bootdata in addition to BIOS bootdata
-Diskpart/apply script with recovery image and multi-boot support v1.2.4*
*To access, press shift-f10 during boot-setup and type: MENU

Notes:
-EI.CFG is present. *You will need to extract the iso and delete this
file to upgrade from a previous version of Windows*. You will also want to
allow setup to download updates during upgrade process.
-Further re-designed integration sources and methods to reduce chances of
install progress errors.

Changes:
-Removed sxs folder. Use the online script in the scripts folder to add
netfx 2-3.5.1 - The sxs folder only adds build 9600 base. The online
version adds the additional files to bring it up to 9600.17031. It should
also add any necessary language information for the feature.
-AutoCRC on the ISO to standardize to crc32: FFFFFFFF
-Added Embedded 8.1 Industry Pro and Enterprise*
*These Embedded versions are the same as their Pro VL or Enterprise
counterparts except that they do not have any APPX modern apps installed
and they have an iSKU feature package and gVLK installed by default.
-Added KB2969339 new servicing stack update to all boot/winre/install
images and upped the scratchspace to 256megs from the default 32megs.
The extra scratchspace just uses a little more ram for the ramdrive so
you can store things on the X: ram drive during winre or boot.

This is only for research purposes, as I (and everybody) already have purchased copies of windows included on purchased computers.
Will be looking at using RT se7en Lite Thanks!
