Windows 7 activation key works on 32 bit and 64 bit?

Hello, I bought an Ideapad U350, which came with a preinstalled copy of Windows 7 Home Premium 32-bit. Because I upgraded the RAM to 4 GB, but my 32-bit OS architecture use only 2, 84GB, so I want to install a new copy of Windows 7 Home Premium, but 64-bit version. The question is (to avoid buying a whole new Win 7 license) will be the product key that came with my copy of Windows 7 Home Premium 32-bit also work on a copy of Windows 7 Home Premium 64-bit? Thank you.

You can use windows 7 key to 32 or 64 bits.

(if you have the key to the home edition, you cannot use for ultimate)

  • HP 350 G1: 8.1 Windows OEM Activation not working anymore?

    Hello

    After asking here on the forum about the restore a deleted partition, what issue has been resolved. We are facing another problem.

    My sister has recently infected laptop computer at a point, it has become UNUSABLE! Kept complete HARD drive, she had more than 400 GB remaining (girl stuff, unlike the guys, they don't download a lot of things); but all of a sudden the drive HARD filled with 400GO remaining at 5 GB

    And... the computer is VERY SLOW at the beginning, it used to take a few seconds to start, but it took almost 5 minutes to start when it has been infected. We tried many antivirus software, the laptop came with a preinstalled (can't remember which), beside that, we tried other software Antivirus, Avast, Kaspersky, Eset and Avira.

    Most of them don't have a scan of C: / drive with an error message such as "unable to scan the c drive".

    Our best option was to reinsert the system.

    I first backep keys of Activation OEM (supposed to be encrypted in the BIOS). I found useful tutorials online which allowed me to show how activation key is beinf used, so I just copied it in a safe place, just in case something goes wrong. I didn't not use a third-party software to view the key! Just Windows tools. A third-party application can not be VERY trustfull in terms of license keys.

    I then downloaded a genuine 8.1 Windows Pro MSDN Web site with a product key.

    The installation went without problems, but when I rebooted I noticed that Windows has not been activated!

    I tried to use the saved key more early, unfortunately it does not work, windows said I can't use this key with this edition of windows.

    My questions are:

    -Can someone tell me WHY I can't use OEM Activation on any edition of windows?

    -Is it possible to make it work on all editions anyway?

    -A complete reinstallation of version 8.1 of Windows non-Pro is automatically enabled by the BIOS?

    -If I buy an activation key for windows pro 8.1, this key somehow will interfere with that in the BIOS?

    Thank you

    It has been activated automatically after I installed a version of windows not pro 8.1.

    Now I understand how it works

  • Windows Vista activation key is invalid.

    We've had this laptop for about 3 years now.  We recently had to take in our repair guy and he re-installed Windows Vista for us.  The laptop worked great since then (several weeks) until the end of last week.

    We started getting a pop up notice to activate Windows.  I was hesitant to click on it until I could talk with our guys from the computer.  In the meantime our wallpaper would disappear anytime we stop or restart the machine.  Then this morning when I started the computer upwards the lower right got the message: "Windows Vista (TM) Build 6002 this copy of Windows is not genuine".

    I called our repair guy and he said that happens sometimes with a re - install.  He said to go and activate Windows.  When I do, before I even get to a place to enter the activation key, the box that opens shows "Windows Vista home premium product key you typed is invalid for activation".

    It follows with the options: "Buy a new product key online", "Type a different product key" or "Contact Microsoft to help solve this problem."  I chose the second option, using the product key on the bottom of our machine and got the message "the product key you entered is not a valid Windows Vista product key.  Please check your product key, and then type it again. "I checked the key and spruced up and got the same message.

    Can someone help me please understand what is the problem and how to fix it?  Or at least provide a way to talk to a living person as the "Contact Microsoft to help solve this problem" option in my head of activation window me to a page that had me trying to activate, which opened in the same window that I had already opened.

    So, after all the time that I spent to fight with this problem and check and recheck the product key, it seems I should actually check the prescription of glasses - I was confused with a 'B' for '8 '.  Once I typed the key * correctly * everything was fine.  I even restarted my computer twice to be sure that all "stuck".  Sheesh, I feel stupid.

    Thanks for your help. :-)

  • Windows 8 CD - Key works only with windows 7.

    Hello

    I had my old computer, windows 7 Home premium installed by default. However, on the launch of windows 8, I paid for the upgrade to windows 8. I have recently bought a new computer, uninstall windows of my old computer (I formatted). And then install windows 7 pro (I watched the downgrade right and that was supposed to work). However, when I try to use my license of windows 8, it says that my windows key 7 is incorrect. Why is - it does not, I do not envy pay for a product that I already paid for.

    Thanks for your help,

    Thanks for the quick response!

    I am a little disappointed by that. It seems that there is practically no way to get windows 7 back. In this case, I could install windows 8.1 from an ISO and use my windows 8.1 CD - key to activate it right? Do you know where I can get an ISO appropriate to do the installation?

    Thank you

    You can use the Windows 8.1 Upgrade Wizard to download the installation files and create a. ISO for which you can use your retail key.

  • How to get rid of the virus Windows 7 activation key product? (Solved)

    Yesterday my laptop ran fine, I was connected to the House of a friend playing a game online with no problems of virus said. Then when I take my computer laptop home and run it a strange thing happened on start up. He said that the program 'autochk' is not found while he was going to skip this program and continue the startup of Windows 7.

    Then I logged in and as soon as I connected the screen said there have been changes to the Windows system and shortly after that pops up another window saying that my Windows 7 was not authentic and that I need to provide my product key to reactivate. I do not give him the key because I knew it was a virus attack, so I do not suspect that I caused the problem to get worse (at least not yet).

    The strange thing I noticed when using my laptop, it's that when I bring up the Task Manager (I used this to try to find any unusual programs running) my username and one other 'user' unspecified wrote in Japanese, Chinese or Korean (I can't tell the difference on a computer). The strange thing is that I have no problem, most of the programs running and in fact have little or no consecutive effects, but I don't want to let this virus stick long enough to prove me wrong.

    I used several programs antivirus and anti-malware, including my own purchased CA security, as well as Trojan Remover, Malwarebytes and Windows security scanner to find the virus said and NOTHING turned up. I fear that this program that has infected my computer could steal personal information so I have really limited my use of games and whatnot, I'd be worried about this information? If so I would like to know ASAP if I change just in case such information. Finally, I'll give you my card to my system if necessary below to help solve this problem. Thanks in advance to all who help, I really appreciate it.

    System Specs:

    Model: Lenovo B560
    Hard drive: 250 GB
    RAM: 4 GB
    OS: Windows 7 64 bit Home Premium edition

    EDIT: I forgot to add that I do not have a background on my laptop nor can I ask my screen and it says in the lower right corner Windows 7 Build 7601 this copy of Windows is not genuine. I also cannot display my internet connection or battery life in the status bar down in the lower right and can not use my laptop built in touchpad.

    I actually ended up having a restore point system a few days before I got the virus, so I ended up just to help that, since I don't have many files added/deleted my account. In this situation, it is what I would recommend to anyone else that it will save you a lot of time and effort. If for some reason you can't use a Hitman Pro system restore point allows you to find the virus (I ended up using that before I decided to use the system restore). This will fix not damage to your computer, but if you want to ensure that it is safe to do something before you use so the anti-virus software, I described previously, he was the only of what I have listed who found the virus.

    @ Sathish S V Thanks for the help despite the fact that I don't end up using your advice, I was surprised and confused at all first when the virus struck but then figured out on my own since it took time to get a response then I needed to solve this problem as soon as POSSIBLE.

  • How can I activate windows no activation key?

    I have an original windows 7 family license premium that came with a used laptop that I bought, but she does not have the activation key, how can I activated the operating system?

    computers that are preinstalled with Windows 7 often 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.

    This is how the recovery partition is accessible to most popular brands...

    For Dell, press CTRL + F11 directly after switching on the device

    For HP, press F11 directly after switching on the device

    For LG, press F11 directly after switching on the device

    For Toshiba, press and hold "0" BEFORE and during the power upward

    For Acer, press and hold ALT + F10, as soon as you see the logo

    For Asus, press F9, as soon as you see the Asus logo.

    For Samsung, press F4 to the power upward...

    For Fujitsu, press the F8 key directly after the power

    Advent, restart your computer. Then, press F10 repeatedly until the message "Starting system recovery"

    Sony VAIO, reboot and press "F8" or "F10" repeatedly until the screen "Advanced Boot Options".

    Apart from that:

    Recommended action would be to contact the computer manufacturer and a recovery of demand media. This will allow that you reinstall Windows 7 Home Premium without requiring a product key.

    This is a random error that continues to be. I wonder if I want to seek a solution, when I do, it seeks a minute then quits or restart the program, when I do closes.

    Hello

    The problem is probably AVG which has caused a lot of problems lately for 8.x and 9.x.

    Frankly, I would delete it. Download but do not install the replacements until AFTER you remove AVG
    and restarted.

    For ALL - download - SAVE - go to where you put it-right-click on Reboot - RUN AS ADMIN - when you have finished

    AVG removal tool
    http://www.Avg.com/us-en/download-tools

    -------------------------------------------------

    Here's what I use and recommend:

    Avast and Prevx proved extremely reliable and compatible with everything I threw at them.
    Microsoft Security Essentials and Prevx have also proven very reliable and compatible.

    Avast Home free - stop any shields is not necessary except away from Standard, Web and network is working.

    Prevx - Home - free

    Windows Firewall

    Windows Defender (is not necessary if you use MSE)

    Protected IE - mode

    IE 8 - SmartScreen filter WE (IE 7 phishing filter)

    I also IE always start with asset if filter InPrivate IE 8.
    (Sometimes you have to temporarily turn off with the little icon to the left of the + bottom right of IE)

    Avast - stop home - free - all shields you do no need except leave Standard, Web and network running.
    (Double-click the blue icon - details look OK. - upper left Shields - those that you do not cancel).
    http://www.avast.com/eng/avast_4_home.html

    Or use Microsoft Security Essentials - free
    http://www.Microsoft.com/Security_Essentials/

    Prevx works well alongside MSE or Avast

    Prevx - Home - small, fast, exceptional CLOUD free protection, working with other security programs. It comes
    a scan only, VERY EFFICIENT, if it finds something to come back here or use Google to see how to remove.
    http://www.prevx.com/   <-->
    http://info.prevx.com/downloadcsi.asp  <-->

    PCmag - Prevx - Editor's choice
    http://www.PCMag.com/Article2/0, 2817,2346862,00.asp

    Also get Malwarebytes - free - use as scanner only. If you ever suspect malware, and that would be unusual with
    Avast and Prevx running except a low occasional (not much), updated cookie and then run it as
    a scanner. I have a lot of scanners and they never find anything of note that I started to use this configuration.
