Windows 7: Switch to trial

15 Jan 2010   #1

Windows 7 Ultimate
Switch to trial

Hello guys,

I was wondering, is it possible to remove the Windows 7 CD key that you did put when you installed it to put the OS back in trial mode ?

I don't think it's possible...
You would probably have to save what you need ...wipe the drive and install the trial version all over.

Windows 10, Home Clean Install

Just so I understand. You are activated and you want to deactivate?

You could simply reinstall the os, but you would have to reinstall your apps as well..

Windows 8.1 Pro RTM x64

Hi Francois and welcome to Windows 7 Forums

Sorry, but that is not possible. The only way is to reinstall without the key (make sure that you select the correct version). You can extend the trial period (see, but after that period has expired you will either have to activate or reinstall. The question is why would you want to deactivate?

Windows 7 Ultimate

Well honestly what's happening is that my girlfriend might leave me and I installed an enterprise cd key on her laptop.

So for security reasons, I want to remove it from there without her having to loose all of her data, I just want her to be forced to buy Windows 7 by herself and do the activation on her own... This is why..

So nobody knows where is the license key stored so I can simply delete it?

PS: TY for the warn welcome Dwarf

I read that, and as I was reading it I was whispering it to myself as if she was listening.

Performing a Repair Install from the Win7 desktop will reset the activation. Just don't reinsert the key until the 29th day, or extend the activation up to 120 days using the popular workaround.

And/or if you feel generous perform the Repair install with the RC .iso...which will give her til May/June of next year...

Windows 7 Enterprise (x64); Windows Server 2008 R2 (x64)

Are you using Enterprise on a Domain or with a KMS server? If so it will expire on its own in 180 days. No problem. Enterprise needs to contact the KMS server every 180 days.

If you are not using a KMS server then you have a bigger issue because you have used your MAK key to activate it and that will take away one of activations from the 25 a MAK key gives you. If you are going to setup a KMS server you will be one short for the KMS Server to start working. If you are not using a KMS server then you are using Microsoft’s KMS server until yours is setup. Microsoft has done a great job of making sure you do not abuse your MAK and KMS keys with Windows 7 Enterprise.

All this will resolve when you setup your KMS Server then Microsoft will transfer the control of activation to your server after you install your 27th machine (plus 1 because of her laptop) and as long as her laptop never connects to your KMS Server, it will be automatically deleted after 180 days from your server. Since Microsoft’s server has given the control to your KMS server her machine will then expire 180 days after your server took control.

I hope that makes sense.

Hub vs Switch vs Router/ 2 Switch Story
I understand that a hub is more like a party line, where all devices hear and read data before sending it to next port, and a switch is advanced hub. But, what is a router. I know what a wireless router is, but they say a router is more advanced than a switch. Can you buy a non-wireless router? ...
