Windows 7 Home Premium - what is - this OA in the license tag? Is it possible to install the OS [Home premium] 64-bit with the same key?

1 What is OA in the license tag
2. is it possible to install the OS [Home premium] 64-bit with the same key.

Hi adil13,

Adding to reply TrekDozer,

1 original Equipment Manufacturer (OEM) Activation is also known under the name of OA. It's basically OEM activation of basic input/output system (BIOS) - which means that they have already activated and you don't need to enter the key and activate yourself.

2. you will only be able to activate a copy of Windows 7 with the number of product key used for 64-bit or 32-bit version at the same time, not both. It will allow only a copy installed with him to be activated. If you try to do it on both versions 32/64-bit, you will probably get the message that your product key is already in use or The Windows 7 product key you typed is invalid for activation .

I hope this helps!

Kind regards

    Hello

    Depends on hardware configuration required on later operating systems, and also find out if the manufacturer of the laptop computer is supported and provides drivers for operating systems later as to whether it is possible or feasible to upgrade or not.

    There is no free upgrade Vista to 7, 8.1, or 10.

    Follow these steps before you buy Windows 7.

    Microsoft sells more than 7; Try Amazon.com.

    Go to your computer / computer laptop manufacturer Web site and see if Windows 7 drivers are available for your make and model computer / laptop.

    If this is not available, Windows 7 will not properly work for you.

    Run the "Windows 7 Upgrade Advisor.

    Hello

    There is no Windows Vista downloads available from Microsoft.

    You can contact your computer manufacturer and ask them to send you a set of recovery disks.

    They should do this for a small fee.

    And if you have never received a recovery disk when you bought your computer, there should be a recovery Partition on the hard drive to reinstall Vista on how you purchased your computer.

    The recovery process can be started by pressing a particular combination of the key or keys at startup. (Power on / start)

    Maybe it's F10, F11, Alt + F10, etc., depending on the manufacturer.

    Ask them to the proper key sequence.

    And if you do not score a manufacturer of recovery on your hard drive, you should be able to make your own recovery from her disks to reinstall the operating system.

    Go to programs > name of the manufacturer of your computer > then their system or recovery tools software topics for them, depending on how it is formulated.

    If you can't find any reference to it, contact the manufacturer for advice on how to make these recovery disks

    Some manufacturers have more available Vista recovery disks.

    If this happens, you may need to try this instead:

    You can also borrow and use a Microsoft Vista DVD, which contains the files for the different editions of Vista (Home Basic, Home Premium, Business and Ultimate) must be installed. The product key on your computer / Laptop box determines what Edition is installed.

    Other manufacturers recovery DVDs are should not be used for this purpose.

    And you need to know the version of 'bit' for Vista, as 32-bit and 64-bit editions come on different DVDs

    Here's how to do a clean install of Vista using a DVD of Vista from Microsoft:

    "How to do a clean install and configure with a full Version of Vista '

    http://www.Vistax64.com/tutorials/117366-clean-install-full-version-Vista.html

    And once the operating system is installed, go to your computer manufacturer's website and get the latest drivers for your particular model or laptop computer.

    And phone Activation may be necessary when you use the above installation method.

  • I need to know the file current date/time number stamp and the version of "spoolsv.exe" in Vista Home Premium 32-bit with SP2.

    I need to know the file current date/time number stamp and the version of "spoolsv.exe" in Vista Home Premium 32-bit with SP2. My spooler file got corrupted and I need to know what that the stamp of date/time on the latest version of the file: spoolsv.exe. I did a search on my hard drive and found 8 copies of the file with 7 different dates. I need to know which copy in my file C:\windows\system32\. I suspect that the problem was caused by some kind of malware. I think that some of the different versions on my machine of the initial installation of the Vista, SP1 and SP2. 3 copies that would explain. I tried all the suggestions in this forum and several others. I tried sfc/scannow and it simply replaces the corrupted file by another. I understand how works this file and a simple copy will do the trick if I knew that the file to use. I know that I don't want to go back to the first version of 2006.  BTW... my symptoms are all my printers have disappeared, and when I try to 'add a new printer' I get an error message saying that my spooler service does not work. When I opened my services window it shows that indeed, he is arrested, but I will not start because the description column contains only the code garbled machine indicating that the file is corrupted, or it may contain a virus. I had been using F-Prot until this virus got by and now I use AVG. I scanned my machine with several cleaning packages and it is is more infected, but I worry that from this corrupt file grow something. I know that the problem is not with my printers or drivers, because everyone on my home network can print on all of my printers. None of the people I know are on Vista 32 bit. They are all running System 7 or XP. I have XP, except that a few years ago I suffered from the "Syndrome of Pepsi" on my laptop and when I bought a new HP, it came with Vista.

    Right-click on the zt.exe file and choose "Run as Administrator" to launch the program.
     
    See if you are able to play the game.

    If this does not work, turn your computer to clean the start State and see if the fgame plays very well.

    To put your computer in a clean boot, follow these steps:
     
    Note: If the computer is connected to a network, network policy settings may prevent you from following these steps. We recommend strongly that you do not use System Configuration utility to change startup options on the computer, unless a support engineer Microsoft directs you to do so. This can make the computer unusable.
     
    1. sign the computer by using an account with administrator rights.
     
    2. click on start, type msconfig.exe in the start search box and press ENTER to start the System Configuration utility.
    If you are prompted for an administrator password or for confirmation, type your password, or click on continue.

    4. on the Services tab, click to select the skin all the Microsoft services check box, and then click Disable all.
    Note: Following this step lets services Microsoft continue to run. These services include networking, Plug-and-Play, record of events, error reporting, and other services. If you disable these services, you can permanently delete all restore points. Do not do this if you want to use to restore the system with the existing restore points.

  • Windows Vista Home Basic 64-bit

    I'm looking for customizable configurations, and I see that you offer with 8 GB of RAM, but it takes a 64-bit system to support it. At the same time, the only option that explicitly says it's 64-bit is the Business edition of Vista, which I certainly don't need. Is it possible to specify a command with Windows Vista Home Basic 64-bit?

    Yes, I know what I'm talking about and I need the power, but none of the administrative nonsense associated with the addition of the company. Wikipedia:

    «Similar to Windows XP Home Edition, Home Basic targets budget conscious users not requiring advanced do not support supports for domestic use.» ... Home Basic supports one processor physical, but with multiple cores. 64-bit Home Basic supports up to 8 GB of RAM. ... Comparable to Windows XP Professional and Windows XP Edition Tablet PC, Windows Vista Business Edition targets the business market. It includes all the features of the basic home edition with the exception of Parental control and the Windows Vista Standard theme. This edition can join and participate in a Windows Server domain. It includes Internet Information Services, fax support, Rights Management Services client, Encrypting File System, image system and recovery, offline files, backup a server to single user Remote Desktop , capabilities of collaboration ad hoc P2P cliché support that allows you to access previous versions of files, Tablet PCsupport and other features of business-oriented management. Vista Business edition supports up to two physical processors. 64-bit Enterprise supports 128 GB of RAM. »

    I am interested in a configuration with a high power, dual-core processor and 8 GB of RAM with the cache of 2 GB drive in addition to that, among other things, large volume, an intense audio processing. None of the additional costs related to the company are things that I need, but I need a 64 bit system to exploit the 8 GB of RAM. Frankly, I really don't want to pay $79 just for the support of RAM, I don't want to deal with it through Microsoft, and while the basic edition is apparently not a Windows 7 free upgrade, I can cross that bridge when I come to it.

    My questions:

    • If I set up a machine with > 3 GB installed memory, will there by default be configured with the 64 bit version of the edition of Windows, I chose?
    • If so, is there a cost difference? There is no difference in cost between the registered versions 32 - and 64-bit Enterprise edition.
    • If not, is it possible to make this simple change to my order? Levono is even included in Windows Vista Home Basic 64-bit?

    buzgun wrote:

    Ehh. The other side to this is that, when you try to maximize the efficiency of an audio production on the fly system, a huge amount of overhead of operating system is not desirable.

    If you after a clutter of OS (which is what you seem to be which means by 'efficiency'), you will need to do significant customization of the load of the installation of any  version of Windows, so it won't be fine well what version start you with.

  • Very big pointer mouse Windows 7 Home Basic 64-bit

    I've had Windows 7 for about 2 weeks now and I'm just in love. An annoying problem that I ask here is that the mouse pointer suddenly becomes very big and it's really a pain because it also becomes big in games, etc... I tried to use the easy access in Control Panel by checking the box for the extra mouse pointer roughly, it becomes larger and after unchecking it becomes the mouse pointer it is 'normal' large size. The only way to solve the problem is a reboot at this time. Please help me.

    I currently have the following machine:

    Windows 7 Home Basic 64-bit

    Intel i5 processor 2, 66 GHz processor

    Gigabyte P55-UD3R motherboard

    Gigabyte card graph HD5770

    Logitech MX518 Optical Gaming Mouse

    Keyboard Logitech G15 V1.0 game

    POWER SUPPLY 600W

    All my drivers are up to date and I can't figure out what is the cause of the problem, it can happen while using Word, play WoW or just surf the Internet.

    Never had the same problem in any other OS.

    PS My e-mail address has changed and has not found a way to change this, so I'll check this post from time to time :)

    Hey!

    After you start the program, click on "Update Bios gigabyte Server"... and follow the instructions...
    This update my bios from F2 to F4 and big the mouse cursor was gone for good...

    hope this helps

    So far so good you method works for me :) Finally something good.

    One thing I have to add that the update online has not worked for me (for reasons unknown, even uninstalled my anti-virus for it) so I'll break down what I did to make it work in case anyone else had similar problems :D
    1. download link Greev84 @BIOS
    2. extract and run the setup.exe
    3. after installation go to start-> all programs-> Gigabyte and made @BIOS right click and choose 'run as administrator '.
    4. click on Yes in the area confirm
    5. now, you should have @BIOS running :)
    6. go on the Gigabyte homepage and download the most recent BIOS for your specific motherboard (if it is more recent than you current which is displayed in @BIOS after 'BIOS sign the Message')
    7 extract the BIOS to a folder, I created a BIOS file on the desktop.
    8. now in @BIOS choose 'update the BIOS from a file' and navigate to the destination to which you extracted the BIOS you downloaded (in my case Desktop\BIOS)
    9. double-click on the file that is not an executable file (see photo). In my case it was the "p55ud3r.f4" - file.
    10. it will display a progress bar that said erase and write according to what he is doing.
    11. restart and run @BIOS to confirm that the update worked :)
    One thing I might add that both has not time my boot OS speed normal, but after that the updated BIOS to update my OS boot become lightning fast! : O
    Photo of the file to choose in part 9 to better understand :)

    You will need to do a clean install, there is no place on the way to upgrade Windows 7 32 bit to 64 bit.

    Using the disk of 64-bit Windows 7, install Windows 7 Windows Easy Transfer Utility from the DVD (to find it, simply navigate to x:\support\migwiz, "x:" is the name of your hard drive. (In this case, you will see a collection of files, the important"that you must search for and double-click is 'migsetup'.) run it and create a DAMP (Windows Easy Transfer file), if you have an external hard drive, you can access it later when you perform a clean install of Windows 7 64-bit disk so you can stored there.

    Once you have done this, just do a clean install of Windows 7 64 bit disc. In Windows 7 64 bit disk, start Windows Easy Transfer, follow the wizard screen, tap on which is stored the WET file (external hard drive) and it will restore your personal files and settings. Reinstall the applications needed.
