Does it really need a fresh install, or could I simply go to Account, Activate Windows and feed it the OEM key there, just like if I had bought a key from the Microsoft Store ? I so don't feel like formating again and reinstalling all that software if it can be avoided.
Thanks in advance guys

Just reinstall, activation is taken care of via BIOS(No COA) or use purchased key if you upgraded.
Can anyone confirm/deny the validity of these methods or make suggestions on how to better accomplish activation after a reinstall? I am mainly concerned with XP since the information I have found is rather scattered and I am not sure if its possible to activate a 'royalty free OEM' using a generic OEM/retail disk install and Windows Key Update Tool or if I would need to use one of the old methods of backing up the files and altering the install disk.
If there are any known issues with activation on any version using the windows images/techniques I listed can someone please elaborate on them. I am asking because I started a new job that requires re-installing every version of windows on various computers that have OEM and retail versions.
The information I gathered on various forums is rather scattered and contradicting, this is why I am posting this seemingly stupid question that you may think has been answered a million times. I want someone to give me a definitive response so I don't screw someones computer up by remove necessary OEM files.

To install on 'royalty free OEM' machines (HP, DELL, etc.) you can get the vendor's oembios files from the oembios repository, or backed up from the current installation.
You then need to use the SLP (system locked preinstallation) key that corresponds to the installation media's product ID. These used to be archived on the My Digital Life forums, but were taken down due to DMCA request. I'm not sure if the particular vendor key is required, or if those provided by Microsoft will work. If you still have the original installation from the OEM, you can extract the SLP key they used for installation from the registry using a tool like produkey.
(Most antivirus seems to complain about produkey, but I've never had issues with it.)
nLite can help you create the ISO and be very useful for testing in a VM, but it's quite a bit more difficult to test the SLP activation with the VM.
Windows 8/8.1
After a fresh install, the system does not auto activate and when one tries to enter the correct OEM Product Key (extracted from BIOS), it is refused. The trick is to first remove the current Product Key with slmgr /upk, then the OEM key can be entered and activation works flawlessly.This idea comes from Clean install Windows 8.1 or Windows 8 from OEM key, which also describes how to get the OEM key using RW Everything (including video tutorial!). Really this has saved me several hours, maybe days of experimenting. If you find it helpful, please upvote that answer instead of this one.
I also created a small PowerShell script to accomplish all the steps in a fully automated manner, which is great for mass OS deployments (e.g. using the amazing OPSI):

Windows 7
I found this techdoors link on activating Windows 7 with OEM licenses to be invaluable.
If you have a computer that has an Windows 7 OEM license embedded in the BIOS SLIC area, and then reinstall a generic image, it will claim to be not genuine. To verify, run this command from a cmd prompt with administrator privs:
It will say 'License Status: Notification', and 'Notification Reason: 0xC004F063'.
To fix that, find the proper OEM key file from this repository from the link above, and then run:
Windows 7 Pro Key Free Activation Keys
where [VENDOR] is the name of your computer vendor.
Now run
again, and it should say 'License Status: Licensed'.
To check your BIOS SLIC area, you can use the Microsoft Genuine Diagnostics Tool and look in the 'OEM Activation 2.0 Data' section.
