• XP Professional x 64 Edition for Windows 7 Professional 64-bit upgrade. The best way?

  Hi you all, experts,

  I want to spend my edition of Windows XP Professional x 64 (legit) to Windows 7 Professional 64 bit. I don't think I need additional options in 'Ultimate', but I need, I am sure, XP mode that comes with "7 Professional".

  Maybe I should mention at this point that I am a member of the program saved Reacondicionador, until you feel that I was fully authorized to "renovate" my own PC.

  First of all a question about Windows 7 itself: -.

  As I said, I need to be able to run certain programs that have been written for XP. The expression "run several Windows XP programs in Windows XP Mode (separate download) company" in "features" means that I have to pay extra for this option? If Yes, how and where to go?

  Is there a reason why my 2D design program which works perfectly under XP Pro x 64 (WOW64) should not be running in the above "Windows XP Mode"?

  Furthermore, I believe that I have several choices on how how to get 'XP' ' 7'.

  1) "OEM", the less expensive but, I understand, once installed on a clean hard disk only, that is all. End, end of story! What should I do if my motherboard fails and needs to be replaced? Can I get a replacement license or I have to buy an another OEM?

  2) 'Upgrade' which I believe will overwrite an existing operating system (matter if it's XP or Vista?) and install "Windows 7". Here are all my existing files maintained? If this is not the case, can I 'restore' to a 'Backup' created by XP?

  3) "Retail", the more expensive but, I understand that, can be transferred or installed on a PC refurbished, although it is only has a license valid on a PC at the same time. Is there a difference between "Retail" and "Upgrade"? Can I use one over the other? If so, why? Is there a difference?

  4) authentic software. Is it possible that I can know without having the product in my hands, or installed on my system, whether or not an article supposed to be "Microsoft Windows 7 Professional 64 bit" is actually authentic. Is there a relevant question, can I ask which would identify a fake before I part with my money?

  Thanks in advance for any help you are able to offer.

  No, Windows Virtual PC with Windows XP Mode is free for users of Windows 7 Professional. To learn more:

  Is there a reason why my 2D design program which works perfectly under XP Pro x 64 (WOW64) should not be running in the above "Windows XP Mode"?

  Personally, I've used several graphic programs 2D and 3D even on Windows XP Mode, include The Print Shop, PhotoDraw 2000 v2 and they work very well to this topic. The article I linked to provide instructions how to publish your applications, you can use alongside Windows 7 applications.

  Furthermore, I believe that I have several choices on how how to get 'XP' ' 7'.

  1) "OEM", the less expensive but, I understand, once installed on a clean hard disk only, that is all. End, end of story! What should I do if my motherboard fails and needs to be replaced? Can I get a replacement license or I have to buy an another OEM?

  No, you will need to purchase a new license if your Windows 7 OEM System Builder License fails. You could of course try install and reactivate the components on the new motherboard before buying a new license, because some people have been 'lucky' get it reactive but is is not a guarantee. If the motherboard is replaced based on a defect or warranty, you should be able to reactivate the replacement motherboard.

  The OEM of Windows 7 versions are identical to the versions commercial full license with the following exception:

  -OEM versions don't offer any free direct support from Microsoft technical support Microsoft

  -OEM Licenses are tied to the computer first you install and activate it on

  -OEM versions allow all hardware upgrades except for an upgrade to a different model motherboard

  -OEM versions does not move directly from an older Windows operating system

  2) 'Upgrade' which I believe will overwrite an existing operating system (matter if it's XP or Vista?) and install "Windows 7". Here are all my existing files maintained? If this is not the case, can I 'restore' to a 'Backup' created by XP?

  If you do not want to restore Windows XP someday, I suggest that you backup before migrating to Windows 7.

  EaseUS TODO Backup free - CNET Download.com

  You cannot upgrade Windows XP to Windows 7. Especially in the case of Windows XP Professional x 64, you need start a custom Setup by booting from the Windows 7 DVD.

• Maximum memory for Pavilion DV7t special edition running Windows 7 pro 64-bit with Intel i7 Q720

  I have an entertainment 2009 Dv7t Special Edition running on Windows 7 64 bit with intention processor i7 Q720 @1 .60GZ. I have 8 G of ram now but need to go to the top. Can I put two 8 G in the slots. Read some reviews say the software works and Windows 7 pro 64-bit can take up to 132 G RAM, if that was even possible. I run two internal drives. But with the addition of the cloud and running photoshop on cloud too much memory is used, slow down the computer. You want to go to 16. Everybody does and no problem?

  Thank you

  Hello

  As mentioned previously, there are SEVERAL dv7t editions and special editions. We have dv7t-3000, 4000-dv7t... and it is very difficult to find the right plug. Please use the following link to find the product/model number:

  http://support.HP.com/us-en/document/c00033108

  Your machine could be the following:

  http://h10025.www1.HP.com/ewfrf/wc/manualCategory?cc=us & dlc = in & lc = in & product = 5292645 &

  If so, the #4 on the following manual page it support 16 GB max:

  http://h10025.www1.HP.com/ewfrf/wc/manualCategory?cc=us & dlc = in & lc = in & product = 5292645 &

  You can have 2 x 8 GB, no choice. Only a few portable computers that have 4 slots and supports up to 32 GB. No way on this earth at this time, you can find a laptop that supports the 132 Gb of RAM.

  Kind regards.

• Validity Sensor does not not in dv7t - 6 c 00 CTO Quad Edition using Windows 8.1 Pro 64-Bit

  Hello

  I have a Pavilion dv7 (dv7t - 6 c 00) CTO Quad Edition (product # A1L77AV) I can't get the validity fingerprint sensor to work after installing Windows 8.1 Pro 64-Bit from scratch.

  Windows 8 drivers that are available for this model do not seem to work. Other drivers Windows 8.1 available in the HP site do not seem to work either.

  The unit shows in the management of the computer as a work, I guess by using a Microsoft Driver. The Unit presents itself as "validity sensors (WBF) (PID = 0018)' in the biometric devices topic."

  Any help will be appreciated.

  Thank you

  Hello SauveDuro, welcome to the Forums of HP.

  I see you are trying to install the drivers for the fingerprint reader on the laptop for Windows 8.1, you've seen questions get this working.

  Unfortunately, HP does not drivers for Windows 8.1 for your laptop.

  The most I can recommend in this case, check the manufacture of each component for Windows 8.1-compatible drivers.  Here's a link of validity, you may be able to get drivers that work for him: http://www.validityinc.com/software/hp/wbf.php.

  This can also help you to: Troubleshooting a (Windows 8) fingerprint reader.

  Sorry for the inconvenience that this may cause. I hope that something can help you.

• I am running Microsoft Windows XP Home edition Version 2002 Service pack 3, use the 32-bit or 64-bit upgrade to Windows 7 Home Premium?

  running Microsoft Windows XP Home edition Version 2002 Service pack 3, used the 32-bit or 64-bit Windows 7 Home Premium upgrade?

  I followed the instructions on the card that came with the software... indicating that, if I look at my computer it was telling me that my computer works... either 64 or 32, but it does not work.  So my question is, how do you know?

  You probably have the 32-bit version of XP (in most individuals, and if your system properties page does not have 64-bit, then you have 32-bit.)

  However, if you now have XP 32 - bit or 64-bit XP isn't the issue that relate to your decision to install 32-bit or 64-bit Windows 7.  This decision depends on the question to know if your hardware can support a 64-bit operating system.  In this regard, the main reason for users to install a 64-bit operating system is to allow the use of more than 4 GB of RAM.  If your hardware does support more than 4 GB of RAM, there is no interest to install the 64 bit version of Windows 7.

  You run the Windows 7 Upgrade Advisor?  With what results?

  Click Start > run and type msinfo32 in the "Open" box and click OK.
  After the system information window has had time fill, click Edit > select all, and then click Edit > copy.

• I have Windows XP Home Edition SP3, 32-bit and IE8. Do I need to upgrade to Windows 7?

  I have Windows XP Home Edition SP3, 32-bit and IE8.  Do I need to upgrade to Windows 7?

  The upgrade to Windows 7 is a personal decision.  Chances are that if you can do what you need to do on Windows XP then it is 'useless' to upgrade.  If you plan the upgrade anyway, you should first check to see that your hardware is supported under Windows 7.  To do this, Microsoft has provided a program of "Windows 7 Upgrade Advisor" to run on your current computer.

• Windows 7 Pro Full Retail Edition - building a new 64-bit machine.

  I installed and registered Win 7 Pro on a 32-bit computer. I have the full retail version, which includes a 32 and 64-bit installation cd

  Now, I want to build a machine separate 64 bit of all new components. I would like to install the 64 bit, Win 7 Pro just to the point where I can check that the construction of material and install Win 7 Pro worked.  I should be able to do it from the 64-bit installation CD.

  When a system of work is done, I can remove my 32-bit computer, install the software on my 64-bit computer and switch the recording of my 32-bit to my new install Win 7 64-bit.

  When I did my 32-bit installation on my current machine, I think I got a 30-day grace period to register for my 32-bit installation of Windows 7.

  This strategy works? Is there a grace period of 30 days? Who should I contact at Microsoft to move to the record?

  Ed Perry

  It would be helpful to know what version of W7's retail, you have (?)

  For example, I have W7 Pro retail.

  The COA license key is good for installation on my computer or any other 'one' computer.

  With retail W7 pro, I can use it to upgrade to a new computer, if my old one died or I just want a new computer (the old OS is more usable however).

  If the HARD disk drive dies I can replace the HARD drive and reinstall without worries.

  I can install 32-bit and in a year I can change to 64-bit (and vice versa if I want). There is no time limit on this for 30 days.

  There is a period of 30 days at the entrance of the key to the COA on the 32 bit or 64 bit OS, and not on the ability to switch.  32-bit is certainly 'old technology' now and also really limits your choice of 3 GB usable RAM Max!

  If your building a new computer, see my article "pinned" Tech PC first about 'breadboarding' a new build :)

  New generation of computer? Test the material first.
