How to reinstall your Express upgrade

Until you do, what I recommend is, after you did the Express of Home Premium Professional upgrade and activate. You should back up your installation as a system. So when you decide you want to start over, everything you do is restore the system image. This will exempt things as the relocation of the base license, reactivation, redo the Express upgrade, then turn it back on again.

http://www.notebooks.com/2009/10/24/how-to-backup-your-installation-of-Windows-7/

The first thing you need to do is to get your key to Windows 7 Professional upgrade Express:
 
An e-mail containing your product key will be sent to the e-mail address associated with your Windows Live ID account or e-mail address you provided if you ignored the account configuration. Note: If you use an email tool or spam blocker spam filter, be sure that you can receive e-mail messages from microsoft.com.
 
What happens if I lose my product key?
 
If you lose your product key, you can return to

www.Windows7.com/GetKey and sign in using the "Sign In" link in the upper right of the page. This will allow to recover your product key if you have established your account with your Windows Live ID. If you do not configure a Windows Live ID account initially there is no record of your online product key. Check your e-mail since it is the only trace of your product key.

The next thing you need to do is to ensure that your data is backed up:

-------------------
 
The next thing you need to do is to reinstall the base license that you upgraded, Windows 7 Starter Edition or Home Premium.
 
If your computer is pre-installed with Windows 7:
 
New computers coming often pre-installed with Windows 7 have what is called a recovery partition. This is used to reinstall an operating system in the case of a system failure. To access it, you need to start when you start your computer by pressing a function key. This can be either F1, F2, F9, F10, F11, F12 key DEL or tab. See the manual that came with your PC for instructions on how to reinstall Windows.
 
 
 
-Samsung uses ESC on most of its systems
 
-HP use F9 on most of its systems
 
-Fujitsu uses F12 on most of its systems
 
-Acer use F12 on most of its systems, but often you need to go into BIOS to allow

-Dell uses F12
 
 
 
In general, look at the screen during the POST for a tip for what is possible.
 
 
 
If your recovery partition is not available or damaged, you must contact the manufacturer of your computer, and request that a defined recovery disk you can use to reinstall Windows 7. They could practice a small shipping and handling.

  • I have Home Premium and want to upgrade to Ultimate.iAm of the India, so not Anytime Upgrade available. Then?

    I have a Home Premium and want to upgrade to Ultimate. I am from India, not Anytime Upgrade available. So? is it cheaper to upgrade to windows 7 ultimate or go to windows 8 is no more information in the microsoft Web site? Is there a upgrade option?
    If Yes, which is cheaper. I have an offer to win 8 Pro only 699 INR. Win 8 Pro is equivalent to Win7 Ultimate? What are the prices for the upgrade from home premium to ultimate victory?

    Windows 7 Anytime Upgrades are no longer available.

    Windows 8 Pro is the ultimate value.

    The only features that you won't find in Windows 8 Pro are Direct, AppLocker and BitLocker Drive encryption access, some of these functions are dependent on Windows Server 2008 R2 or a later version.

  • can upgrade you vista Home premium to vista professional in order to install windows 7 Professional upgrade?

    Husband bought the windows 7 Professional upgrade.  Of course when it did not work and the message was to do a "clean install", we both had type light headed as we thought it that will take all day and probably does not work smoothly since is the most "literate" computer.  I did some internet research and according to microsoft, windows vista business upgrade to windows 7 Professional is an upgrade and not a clean install.  Is it useful to try and uprade my 64-bit edition windows Home premium windows vista professional in order to upgrade to windows 7 Professional?  I don't think we can get our money back because the packaging is open or I would say just that we trade it for ultimate.  If anyone can help I would really appreciate it.  Also I don't know even where to download vista business or haow only as much as it would cost.  Thanks in advance.

    N ° there is no way to go from Vista Home Premium to Windows 7 Professional OR Vista business without what you call a 'clean install', so there is no point in spending money to upgrade to Home Premium to business before the upgrade to Windows 7 Professional.  Upgrade Vista Home Premium only allowed on-site is ultimate.

    Use Windows Easy Transfer to keep your files and settings.  Then, start the computer with the Windows 7 dvd installation and moving forward.  Do not remove Vista.  Windows 7 upgrade installation should detect a copy installed Windows so that you can use the upgrade product key.  Once you reach the installation type selection screen, you will see the upgrade option is grayed out.  Choose the custom option to continue.

    If you want to do a clean install, you can use the tools on the installation type selection screen (until you click on custom) to reformat, etc., but this is not necessary if you don't mind remove the old Windows folder later.  If you start with a blank hard drive your upgrade license will be a problem then don't attempt is not a clean install of the old way.

  • Upgrade Windows 7 Home Premium with the Professional Windows 7 upgrade software?

    I got a deal to get the Windows 7 Professional Upgrade for $ 100, thought that I get it.  Only now I realize that I had Vista Home Premium on my laptop, and so impossible to move to Windows 7 Pro.  I went out and bought the Windows 7 Home Premium Upgrade today for another $ 100 to upgrade.

    Basically, can I use this software to upgrade Windows 7 Professional upgrade the copy of Windows 7 family upgrade that I just bought. If I can do:

    Windows Vista Edition Home Premium< windows="" 7="" home="" premium="" upgrade="">< windows="" 7="" professional="">

    I hope I explained this correctly.  I don't want to really not get stuck with a copy of Windows 7 Pro upgrade software that I can't do anything with.  Any help would be incredibly useful.

    If the license for Windows 7 Professional, you have access to is a retail version update or complete, you can use the product key and the Express upgrade to Windows 7 Edition Home Premium to Windows 7 Professional. Click Start, type Anytime Upgrade, follow the on-screen Wizard, enter the key to Windows 7 Professional on demand, click on, and then restart your computer when you are prompted. Less than 10 minutes, you should be upgraded to Windows 7 Professional and your files and settings retained. Andre Da Costa http://adacosta.spaces.live.com http://www.activewin.com

  • Reinstall windows 7 Home premium 64 more Professional 32-bit I

    I'm in trouble. Recently, I paid a techie local to reinstall Windows.  I had W7 Home Premium 64-bit installed but it installed W7 32-bit professional.  I am trying to reinstall Home Premium 64bits but the installation process will not work

    I get a message saying that the version on the disc is not compatible. He said that I should reboot with the installation disc, but it doesn't work either. The installation process does not start.  Research on the net, it seems perhaps not possible to move from a 32-bit to a 64-bit if it is a different level of Windows. Is there a way to turn it?  If this is not the case, can I initialize the C drive and reinstall W7 Home Premium 64-bit from the installation disc?  Finally Microsoft support say Icould upgrade to W8.1 64-bit. Would this work?

    I just upgraded my Windows 7 64 bit Home Premium computer to Windows 7 64 Bit Ultimate Edition.

    Vista Home Premium to Vista Business is NOT an upgrade path.

    You will need to purchase a FULL version / license of Vista professional and do a clean install of it.

    How to do a clean install:

    Go to your Bios/Setup, or the Boot Menu at startup and change the Boot order to make the DVD/CD drive 1st in the boot order, then reboot with the disk in the drive.

  • Cannot switch to WIN7 Home Premium to WIN7 Professional

    All trying to solve a problem with Windows Update will not download updates, I fear that a cleaner spyware I used at the time, this problem occurred firstly has deleted some registry information (and I thought that that may have caused problems with Windows Update), so I decided to try upgrading my Windows 7 Home Premium to Windows 7 Professional (64 bit).  I have the DVD upgrade, because a year or two ago I upgraded my computer to Windows 7 from Windows XP.  When this desktop computer began to die a slow death, I uninstalled Windows of the player and the computer put on the scrap heap.  With this update has been successfully uninstalled, I thought that I could use it to upgrade my Windows 7 Home Premium (OEM came on my laptop which I use exclusively now), but when I tried, installing told me I could do only either a "custom installation" that would have wiped out any and all other programs and files on the laptop , or use the Express upgrade.  When I tried the Express upgrade, he initially asked me my product key I then typed in and validity verified, began the upgrade process and then told me that he could not put to Home Premium upgrade to the professional version, even if also seem to indicate that he might.  Maybe that's a problem with my Windows 7 Upgrade DVD that was used before and the product key being somehow in the system as "being used?"  If so, what are my options?
