Advice Request Refreshing windows 8

[ElectricSheep]

Not sure if this is right section, but as I want to refresh my OS, thought I'd get some feedback.
I run windows 8.1 but as my system has 8 built in, if I refresh, I have to reinstall 8.1 which takes ages to do... You know, all the "setting up", multiple restarts, etc.
Has anyone got any faster method of reinstalling 8.1 as I don't want to sit around for 90 minutes just waiting for it to finish configuring and all that?

If there's no quicker way, fair enough. Just on the off chance one of you guys has a shortcut kind of thing

Any advice would be appreciated

You could download the 8.1 ISO image from Microsoft (Google this), but you'll need a spare License Key. The Win 8 license won't work on 8.1.
However, the upgrade from 8 to 8.1 via Windows Store is free, but it takes a lot of time depending on your Internet connection and / or any driver updates.

Don't tell the security freaks, but I'm still using Windows 8.0.

Exactly what I've done in the past, using the free upgrade from the Store, but it takes aaaaaaaages
