DownGrade Windows 8 Pro 64 bit on 4540 s HP Probook Windows 7 Pro 64-bit


can someone tell me the correct procedure to downgrade pre-installed 64-bit Windows 8 Pro that came on my laptop 4540 s newly purchased to Windows 7 Professional 64-bit? Machine itsself comes not with any media. I also read the key is now also integrated into the BIOS. As I intend to replace the 500 GB HDD with a SSD 250 GB, I would like to re - install windows 7 at the same time. I know that you can download the vanilla windows versions 7 of and others and then install but I wanted to know if there was a formal process for HP machines. It would be also good to know that the process of extraction of the COA, so I can activate Windows 7 installation completed.

I am based in the United Kingdom (and an employee of HP)

(it seems I'm not the only one having this problem - I guess this method works )

but before could someone confirm that part "call microsoft" will be ok for me if I have no physical cost... also what can I do if I have not a pro windows 7 product key to enter during the installation of windows 7 - because obviously I intend to use the rights to downgrade to windows 8 pro key!).

advice appreciated.



so having figured out that I can downgrade sounding MS I took the lead and mounted my new SSD drive and installed Windows 7 Pro 64 bit. Everything is good. What I need now is some of the correct drivers to get me going.

If someone could point me to the right for the following, I'd be grateful so I don't waste time to download everything. My version is HP Probook 4540 s C4Y79EA (i5-3210/4 GB RAM/15.6 inches) model British.

Some of the choices pilot have several versions of pointers to good enjoyed.

It is mainly in the field of the network drivers for the Wifi and fixed ports.

Thank you.

I determined what hardware is in this model.

WIFI/Bluetooth - download drivers Ralink

Ethernet card integrated - download the Realtek drivers.

The rest should be pretty straigtforward...

  • Satellite T230 - Downgrade Windows 7 64 bit to 32 bit


    Can you please help. Just a week before I bought the Toshiba Satellite T230-10j. The laptop comes with Windows 7 64-bit edition. It has the recovery partition and no other support provided with the same. Is it possible to downgrade from 64-bit to 32-bit OS. If so can someone please provide the *.wim image. There are a many applications doesnot support 64 - bit os and the only way for me would be the Windows 7 32 bit.

    Can someone guide me how to proceed further with this.

    Kind regards

    Hi mate

    As much as I know the laptop won't was delivered with any disk recovery because you could create a clean recovery disc image using the Toshiba Recovery creator software that was preinstalled on your laptop.

    In addition if you want to downgrade the Win 7 64 bit to 32 bit then you will need to purchase the 32 bit version.

  • Can I downgrade my Satellite Pro P200 for Windows XP?


    I bought my Satellite Pro P200 (PSPB7E) a week ago and I love it. I have an unused XP license, so I would like to downgrade.

    Is this problem? I don't see xp for a Chicony webcam drivers or the HD-DVD player.
    I'd really appreciate some feedback. There must be someone out there who has tried to do.

    Thank you in advance!


    Of course you can downgrade the satellite Pro P200 for Windows XP.

    When installing XP, you need to install the Intel Storage Manager. It is a SATA driver that is needed to activate the HARD disk.

    Regarding the webcam driver.
    I checked the page European driver of Toshiba and the Chicony webcam driver is certainly available.

    The HD DVD driver is not necessary because the Windows XP must use an own ODD driver.

    See you soon

  • Can I downgrade Windows 8 64-bit for Windows 7 64-bit?

    Can I downgrade Windows 8 64-bit for Windows 7 64-bit?

    And also my drivers continue to operate?

    I have only one installation of Windows 7 disk and want to make sure that I could use it incase if my computer goes down / gets corrupted / ect. Since I formatted acccidently my OEM drive when I take away a lot of partitions, I did.

    My computer:

    Model: HP 2000 Notebook PC

    Model No.: C2N26UA #ABA

    OS: 8 64-bit Windows

    Additional info: my computer came with Windows 8 64-bit pre-installed.


    First of all, make your game of W8 recovery discs before proceeding.

    All the W7 x 64 drivers of this Associates model should work on yours.

    The driver is missing (and is for any laptop AMD) and it's the chipset driver that installs the SMBus Controller and the USB 3.0 controller.

    You should download and install this driver first and then restart. First download listed is what you need.

    Then install the graphics driver and restart, then install the audio driver and restarted.

    Is it possible to downgrade Windows XP Professional 64 bit to 32 bit? How? Please advice. Thank you!

    There is no downgrade option, you must perform a clean install of Windows XP 32-bit and reinstall your applications. Don't forget to back up your data files and check that you have the product keys and installation media for even before you start.

    How to do a clean install of Windows XP

    Start by changing the BIOS setting to start from the CD drive first.
    Then see below:

  • Devices Satellite Pro L300D-110 - downgrading to XP Pro - HARD drive missing?

    Hello to everyone in the Toshibe Satellite Pro - my first post forum.

    I was one proud owner of other portable Tosh without any problem, but this time, I'm miserable: (o)

    For professional use a few days ago, we bought a laptop Satellite Pro L300D 110 (AMD Athlon Dual Core). We bought it with the understanding that it could be brought back to XP Pro - mainly because some of the software that we use on a daily basis does not work reliably on Vista, but also because all other laptops to desktop computers in our network (including a WLAN) all running XP Pro, adding another machine that it should have been easy.

    The need to do so has been confirmed by the fact, nevertheless, I tried, we could just not get the new Toshiba L300D connection through our routers so that under Vista. At the same time, we also bought a new Dell with no o/s. I installed a new copy of XP Pro SP2 OEM - and it runs under the sweet as a nut! Sorry, I digress:

    I reduced the L300D to XP Pro very well using the XP Pro provided - Toshiba Recovery disk no problem at all. I had the computer connected to the network too, but then I realized that the DVD (Pioneer DVD - RW DVRTD08A ATA) is not found by Windows.

    Logged in the BIOS setup - Yes, he was listed there OK, but tried some tongs and tricks I have learned over the years, I still couldn't XP Pro to the discovery of the device.

    I have now reinstalled Vista on the machine and he found the DVD burner.

    If it's a PC, I shut down the computer, open the case, disconnect the writer, start, stop, reconnect the device, close case and bingo. But not with perhaps a laptop...

    Someone has ideas how (reliable!) downgrade to XP Pro without devices being endangered? Any help would be greatly appreciated.

    I have two copies again more XP Pro SP2 at my disposal, if that's any use.

    Kind regards


    (> I'm happy again now: o)
    Great to hear that!

    Just for info:
    The most recent series of portable supports the newer SATA HDD controllers and so the operating system can be installed if the SATA drivers are not included and preinstalled.

    So if you want to use the SATA features you must first install the SATA driver.
    But you can also activate SATA mode to compatibility mode (in BIOS) and this would install the Win XP without the necessary SATA drivers.

    Good bye

    Thank you very much.

    I searched the net and I found no official sort of downgrade WMP 12 WMP 10 so officially, that you can not downgrade Windows Media Player

    In any case I found a site where apparently someone has found a way to downgrade, , but the procedure is not only allowed and supported by Microsoft but it is also very dangerous and I have not yet test (and I think it should work only in the 32-bit version), so do it at your own risk!.

    Good bye.
