Better To Upgrade Install Or Clean Install ?
Oct 23, 2009
I'm finding this decision quite hard to decide on and can't decide what to do. I am very picky about wasted space or unnecessary stuff on my hard drive, yet I'd rather not install everything all over again which will take about 20 hours or so.
My question is...if I do an upgrade-install, can I just delete everything in the Windows.old folder and have everything practically the same as a clean install? Or will there be still be some left over things from the hundreds of programs I've installed and uninstalled?
Edit: I've ran the Windows 7 Upgrade Advisor and everything seems ok.

Does anyone know whether there is a difference in performance between doing a clean install of Windows 7 vs upgrading Vista? Any better stability? I'm just wondering whether it's worth the trouble of the clean install.

I originally did the upgrade install of Windows 7 from Vista to Windows 7. I am seeing that I now am running "ChkDsc" every time that my computer is shut down. I was told that I would be better off to do a clean install and reinstall programs and files. Can I do a clean install with my upgrade disc, or will I be creating additional problems ?

I have a couple questions I have been trying to hunt the answers down for. Im super paranoid considering the not so easy to find rules and regulations Microsoft has for its software.I currently have an OEM version of Windows 7 Home on my laptop. I was wondering if:
1. I can upgrade from a Windows 7 Home (which was pre-installed on my laptop) to Windows 7 Professional using Windows Upgrade Anytime? If so,
2. Will problems that I have on my current windows transfer to the upgraded version? If not,Is it possible to do a 'clean install' of the upgrade?

Anyway, I am running build 7022 x86 and was planning on upgrading my maching and going with x64. First, is this possible as a simple upgrade? If so, are there any concerns or issues I should know about when attempting this? A clean install is not out of the question but obviously when testing these new builds, its nice to be able to just upgrade.

We already tried the link for the steps to do a clean install. Clean Install Windows 7 We still get 0xC004f061 The software licensing service determined that this specified product key can only be used for upgrading, not for clean installations.
We have a full older version & hoped sticking it in the hard drive would allow Windows 7 to find it. We really don't want to have to install the old one then the new one.
Problem with the detailed instructions was we got to the Activate window and we never got the Automatically activate Windows when I'm online checkbox. Just typed in key hit (Next) and it went through it's activation check & didn't like us.
Problem is we have been at it all day and this is like the 10th time we installed it. Computer had a virus. Took it a while to confirm the Bootable section of the hard drive was fried.. So we really don't want to take it down again, in order to install an old OS so the upgrade can "see" it.

I have an acer laptop which came with vista, i then upgraded it to 7 with the upgrade that acer sent me. I made an image of it which i had to use after getting a virus. I now want to install a clean installation of 7. After reading some of the other tutorials which said you can use the upgrade dvd to do this, i tried it but with no joy. I changed the BIOS to boot from DVD drive but the upgrade DVD does nothing.
I have the acer recovery discs but they were made when the machine had vista on it. i've used them but after i use them the "bootmgr is missing" and i have use my image again to get the computer up and running again.

Ok, now that Windows 7 is out "officially" who do you guys think?
I installed fine using Upgrade from Vista SP2 Ultimate. Everything worked fine without any new driver install. All my programs worked right away.
I like the system, I like the speed. So I keep asking myself will it be better if I install again in a "clean install" way?
What's your opinion, what's better? And what you did?

Can you fresh install with an Upgrade version of Windows 7? I want to save some money by buying the Upgrade. However, if I have to install my old OS first then upgrade, that isn't really a clean install. I'm wondering if you simply have to prove you have an older Windows version so that you can upgrade, or if it literally has to be on the PC for it to work.
Second, does anyone know if the Upgrade trick works with Win 7? As in, you install the Upgrade without entering a key, then "upgrade" your upgrade?

What is the received wisdom on upgrading from Vista to Windows 7? I have always been in favor of clean installing but is there any advantage in reformatting and clean installing in this instance?

i like fresh installs on a Zeroed hard drive. i got win7 64bit but its an upgrade disk only. i have legit xp64bit right now. my question is this. the option that says " all information will be lost" or something like that is that a fresh install where it formats the drive and then installs a fresh windows 7 install? or does it just convert the old files and like a normal install?

Clean installing Windows 7 x86 is no problem. But
1) upgrading Vista x86 to Windows 7 x86 fails and automatically rolls back to Vista, and
2) attempt to clean install Windows 7 x64 results in BSOD when rebooting to finalize the process.
Any suggestion would be appreciated.

With VISTA, you could not install a fresh copy, you needed to upgrade your existing OS. (unlike XP, 2000, etc.)
Did this change with 7? Can you do a clean install from an upgrade 7 DVD?

I did a reformat of my hard drives, completely clean, recently, and reinstalled my copy of Windows 7 without problems. However, the activation did not go smoothly, my key is a Windows 7 Home Premium 64bit UPGRADE key, and it told me that it couldn't be used.
I have read the other threads on this subject, but couldn't figure out if there was another way or not to deal with this situation, other than buying another copy of windows, or wiping again, installing xp or vista, and then upgrading.If possible, I would prefer to not have to reinstall windows, or move my files around, because I was borrowing the external drive I used to reformat the first time, and I'm currently in college.

Is there a difference between a clean install of Windows 7 Professional and upgrading from Windows 7 Home Premium to Windows 7 Professional?I ordered a computer and I require Windows 7 Professional, but they accidentally sent me one with Windows 7 Home Premium. They have offered me a Windows 7 Professional Upgrade disk as a resolution to the problem, but I'm worried an upgrade may not be as stable as a clean installation and I'm not sure if I should accept this resolution.

I'm currently running Vista Home Premium 32-bit.
I'm going to buy Windows 7 Home Premium 32-bit upgrade.
I want to do a clean install on a new hard drive I just bought.
I'm going to put the current Vista hard drive on SATA 1
The new hard drive for Win 7 will be on SATA 0
I can't figure out what procedure to use so Win 7 Upgrade sees the old activated Vista to activate Win 7.
In short, I want a clean install via Win 7 upgrade media on a seperate hard drive.
Can anyone help with this?

I have never done an in-place upgrade, so I am a little confused. One very knowledgeable friend told me that the in-place upgrade essentially runs a Windows Easy Transfer, does a clean install, and unpacks the transfer file, all automatically. Is it true? Is there a difference between doing an in-place upgrade and just using Easy Transfer?

As you're aware, Vista had the 'capability' to do a clean install using the Upgrade DVD.
You could boot from DVD, do a clean install, not validate, then when in Windows, go to the DVD drive and install again, this time doing an upgrade and then validate.
This seemed to be kosher as reported on many sites. I know people who did it and all was well. Their Vista PCs run fine, and are completely up to date with regards to SPs and updates.
So, for an Upgrade price, it was possible to do a fresh install...will Windows 7 have this capability do you think?

I have Vista Ultimate installed today. I intend on buying Windows 7 Home Premium upgrade. I would like to install 7 on a new WD Caviar Black I just ordered as a clean install.
1) Is this possible or will Win 7 flag this as a new install because of the new HD and not let me proceed since I plan on buying an upgrade disk?
2) If not, what options do I have?
3) If I can do this, can I plug my old drive in as Drive D: or E: to transfer the data over?

Just to let you all know that I have confirmed that you can do either a clean install, custom install, or upgrade install with a retail Upgrade version of Windows 7 and activate it on a clean unallocated (blank) drive or partition without any other OS installed or with one installed. It does not matter.
WARNING Â
Remember that you need a valid qualifying previous version of Windows to use a Upgrade Windows 7 copy legally. Microsoft only made doing a clean install from a upgrade Windows 7 possible to make it more convenient so you do not have to reinstall both the old Windows version (ex: Vista) and upgrade to Windows 7 everytime you needed or wanted to reinstall.
If you do not have a valid qualifying previous version of Windows, then you are violating the terms of Microsoft's Windows 7 End User License Agreement and could get your product key number invalidated by Microsoft. Plus, it is considered illegal.
For more about this, please see: Microsoft SMB Community Blog : Regardless of what any hack says, a Windows 7 Upgrade is an Upgrade. What you need to know.

I plan to perform a clean install using a Windows 7 Professional
upgrade disk.
- I have a laptop that originally came with OEM Vista Home Premium.
- Subsequently, the O/S was changed to Vista Ultimate (full version)
I would like to be able to install Vista Ultimate on another PC; to do so,
should I install (full format) the OEM Vista Home Premium prior to
attempting the upgrade to Windows 7?

i am planning to buy the upgrade version of Windows 7 (i have genuine vista) but im planning on buy it online from the microsoft store, i read the clean install from upgrade sticky but i noticed this; ' This will show you how to do a Clean Install using a retail Upgrade Windows 7 installation disc.'
I notice the words 'retail' and 'disc' i am wondering if i download the official version is that considered retail? and im not really sure how it works, i have never downloaded an OS before, do i need to burn it to a disk once its downloaded?
If so will it then work like the regular disk allowing me to do what the sticky then goes on to explain, or will it know its my home made 50cent disk and think my copy is fake?

My question is Can You Do A Custom Clean Install Using A Upgrade Version of Windows 7? I already have a valid OS installed on the hard drive. I am using Windows Vista Home Premium right now. I am wondering if I can do a custom clean install of Windows 7 from an upgrade disk of Windows 7 Home Premium? I don't want to upgrade because I am afraid I won't get the best performance and I want to have a 'fresh new OS'. It is cheaper to buy the upgrade then the full.

As you may know, you can purchase Windows Vista Upgrade Edition at half the price of the full version, and do a clean install from a blank system pretty easily - you do a clean install but do not enter the product key, then do a re-install from boot and this time enter your upgrade key - voila, a clean full install of Vista.
This is useful for those of us who own a previous version of Windows but want to do a clean install (previous versions of Windows allowed us to insert previous CD to prove ownership but Vista doesn't for some reason).
Does anyone know if this trick will be available for Windows 7? As a genuine owner of Vista, I aim to buy the upgrade edition of Windows 7 but always do clean installs and never 'soft' upgrades so I don't want to have to install Vista first each time.
