Doing a Clean Install with a Upgrade Windows 7 Version

[gregrocker]

Unless you wipe the HD first, when you boot from the DVD it will see the OS to allow use of Upgrade version key upfront during install. If not, leave the key blank until after install then do the quick registry workaround given, activate at Computer>Properties>scroll down.

Adapt these steps to get a Perfect Reinstall.

Thanks! So no need for the double install, but do I still proceed with Manual activation?

 

[gregrocker]

I never uncheck auto-activation unless there's a need to wait the full 30 days to activate. You should know in a day or two if this is the install you want.

Hello. I need some clarification. When I bought my pc, it came installed with Win Vista Home 32 Bit. I have since then upgraded to Win 7 Home 32 Bit using upgrade discs provided by the Mfg. Will I be able to do a clean install of Win 7 as well even though I have a vista COA?

 

[gregrocker]

Yes, as long as you saved the Product Key for your Win7 Upgrade version.

When you boot the DVD to clean reinstall, it will see an OS on the HD and allow use of Upgrade version key during install. If there is no OS on the HD then you'd leave the key blank during install and afterwards do the quick registry workaround given in this tutorial to activate Upgrade version on new or wiped HD: Clean Install with a Upgrade Windows 7 Version

I apologize if this question has already been answered, but I am guessing it hasn't:

Currently, I have the OEM license (different from the retail license on the sticker on my comp) active, but the ability to change it to the retail license on the sticker. I haven't tried because I didn't know if it was necessary/safe/possible, but would doing this assuming it works, have any effect positive or negative on the upgrade clean install process?

Thanks in advance!

P.S. Do you have the words "Boot From CD" assigned to some sort of hot key or shortcut for this forum? I am just trying to understand how you have the patience to literally say the same thing for approximately 33 pages?

The license on the COA sticker affixed to computer would be Factory OEM if you have a computer which came with preinstalled Win7. The Product Key on sticker is used to clean reinstall it - otherwise running the Recovery partition or Disks will auto-activate using factory mass activation method. To clean reinstall Factory OEM with the Product Key on COA sticker follow these steps: Clean Reinstall - Factory OEM Windows 7 - Windows 7 Forums .

A retail license is Full Version, Upgrade version or Builder's OEM which come with COA sticker in package. Is this what you have now? You can change a retail install of the same version to Factory OEM using the COA sticker Product Key, or vice versa. Just let us know which exactly you want to do as it isn't yet clear.

Well I'm not quite sure really. I just really want to make sure that my upgrade from Vista x32 to 7 x64 goes as smooth as possibly, and I am leaning towards going with your method here, of purchasing just the upgrade license. Let me illustrate what I mean about the differences without actually posting a product key here.

When I go to system information, the system key reads: XXXXX-OEM-etc... (it's visually segmented differently than the sticker on my tower)
The sticker on my tower reads: XXXXX-XXXXX-etc... (no "OEM")

I have the option to change the key in system information. What is the difference between the two keys, as they are obviously different keys...but do the function the same? Are they connected to one another? Should I activate the sticker key before attempting to upgrade or at any point in time?

 

[gregrocker]

That isn't the key in System Information, it is the Product ID. The OEM means it is factory preinstalled.

No key is used or in any way referenced during upgrade except the one which comes with the Upgrade. You don't even need to have the qualifying OS installed to use Upgrade version as you can get a superior clean install even on a blank or new HD using a popular workaround given out by MS.

Otherwise the Upgrade installer when booted sees an OS and allows use of Upgrade version key during clean install. Clean Install Windows 7

Hello Warlockz,

Did you also try OPTION THREE in the tutorial below for the error?

[Warlockz]

Im probably going to try this one in the pic, "Control Panel\All Control Panel Items\Recovery\Advanced Recovery Methods" but not atm, The Netflix silverlight error, media Protection crap after I changed motherboards to a working MB, how annoying....Netflix isnt so important to me anymore, what a crappy selection, im just using a VM to view them atm instead......

I bought and downloaded the upgrade version of Windows 7 Ultimate 64-bit years ago and upgraded over my Windows Vista Ultimate 64-bit.

I just upgraded my motherboard, processor, etc. and decided that I should reformat my hard drive to clean up old junk and get the most out of my new setup.

Today, I downloaded the upgrade version of the Windows 7 Ultimate 64-bit iso and burned it to a DVD. Just so I understand, can I run the setup.exe on the DVD while in Windows 7 and do a clean install? Or, do I have to boot from the DVD and clean install that way?

Thanks in advance for the advice

 

[gregrocker]

It's best to boot the installer so you can use Custom install Drive options to delete all partitions and create new ones as you wish. The installer will see an underlying OS to allow use of Upgrade version key during install.

These steps to get a perfect Clean Reinstall - Factory OEM Windows 7 are the same for retail.

Do I need to find an XP disc?

I'm sure the answer to this is in here somewhere but struggling a bit to find it.
I bought a dell laptop with XP pre-installed (didn't come with a disc...) and then bought a Win 7 upgrade disc and have upgraded. I now want to replace the hdd but do a custom install. Will I have difficulties activating after the custom install on the new hdd? I have the XP sticker with code on the bottom of the laptop, but I assume this would only work for a new XP installation.
Do I have to try and find a Dell XP installation disc, do the XP install on the new hdd and then the win 7 upgrade - or can I just use the win 7 upgrade disc.

Apologies for the laziness of this post as I'm sure the answer is on the forum somewhere - if someone could point me in the right direction I would be most grateful....

You won't have difficulties activating the custom install of Windows 7 if you have a 25 character Product Key from the Win 7 upgrade disc you bought.

The XP sticker is uselss for a Windows 7 installation.

You don't need a Dell XP installation disc. You don't need to install XP. Just go directly to the Win 7 upgrade to the new HDD with no other HDD connected.

 

[tlondon]

Thank you for your swift reply ignatzatsonic.
Out of curiosity, if you can do a custom install and activate it from the win7 upgrade disc key, what differentiates the win 7 upgrade disc from the full win 7 disc?

 

[gregrocker]

The Upgrade version Product Key is only good to use if you have a qualifying XP or Vista which came with the PC, or a retail copy of either on hand. The installers are all the same, with certain versions unlocked.

The qualifying OS doesn't need to be preinstalled but if you install to a blank or wiped HD you'll need leave the Product Key blank during install then aftewards do one of the workarounds in this tutorial. This workaround is provided as a convenience to avoid having to double-install.

If there is an OS on the HD then the booted installer will see it to allow use of Upgrade version key during install, even if you then use Custom>Drive Options to delete partitions and/or repartition during install.

So will this work? I have a friend who has 7 Home Premium x86 installed using an upgrade disk that does not have SP1 onboard (he upgraded from Vista). The OS is messed up and he wants to format and reinstall. I offered to burn a copy of 7 Home Premium w/SP1 x86 for him to save a lot of updating. Will his key work?

 

[theog]

Will his key work?

His key should work for Windows 7 Home Premium x86 & x64.
