  • Windows 8.1 upgrade is not possible because win 8 is not enabled

    A few months ago, I bought a new laptop of Toshiba Satallite with 8 Windows preinstalled
    Now I want to upgrade Windows 8 to 8.1 Windows. But I don't see the upgrade of Windows 8.1 in Windows store. I think it's because my current installed windows seems not you be activated...

    When I try to activate, I get error: 0xC004F074.
    I found a solution using the command: SLUI 3 and then enter the product key to activate it, but I don't have a product key! There is no sticker with a product key on the laptop.

    Could someone help me with this question, so I can activate my current installation of Windows 8 and upgrade to Windows 8.1?

    Hello

    I had some problems with an upgrade to 8.1 to win in the past...
    Finally, I managed to install the Windows 8.1 update once the laptop has been set back to factory settings.

    I'm not sure if this should be done in your case, but where the 8.1 Win update is not possible after installing all the windows updates, you should reset the PC back to factory settings. After that the upgrade should work.

  • Pavilion 6650z: upgrade Windows 10

    I was wondering if an upgrade to Windows 7 SP 1 Windows 10 could prove useful. My desktop computer Pavilion meets all the hardware requirements to run Win 10. It's a CTO in January 2011.

    I've already tried an update to Win 10 on-site the weekend of the new year, earlier this year. While the update process, the indexing for my Corel Photo Paint Shop Pro X 3 process lasted several hours with no end in sight. It is at this time that I decided to go back to Windows 7. Could not find the link "back to the previous Windows" in the Windows 10 settings, I used my system recovery disks to reinstall factory on my Pavilion.

    Before considering a new attempt to upgrade Windows 10, I would like to know if it's worth my time and effort to install Win 10. Also, I would like to know which is better: an upgrade in place against the clean install.

    I read Windows 7 machines that met in the hardware configuration required to win 10 has failed as well in the upgrade process, that the results are mixed at best.

    Thanks for your help.

    You are right to be cautious about making the upgrade of Win10 on a Win7 PC.

    I did it on several\ PC Win7 and it completely trashed both of them - where they were to be restored to factory settings to restore operation.

    I wrote the following to inform people about the measures to be taken during the upgrade PC Win7 to Win10...

    Desktop computers older Win7 tend to fare badly when upgraded to Win10 - mainly due to lack of HP Win10 drivers for older hardware.

    If you are determined to upgrade to Win10, you must be willing to do four things:
    (1) do a full image backup of disk external drive or USB stick, capacity
    (2) changes to the reserved system partitioning hard disk recommandΘes mΘthodes,
    (3) use a different approach and maybe more than one, as Windows Update to do the upgrade,
    (4) prepare for a clean install.

    ---------------------------------
    1: backup of images:
    This is VITAL, because the machine is doomed to failure of the upgrade, and when that happens, you will learn that GoBack to Win10 function is NOT reliable, and that can leave you with a corrupt machine that will require the factory reset and lose all that on it, to get it working again.

    You can avoid this by making an image backup to an external hard drive or a USB drive using Macrium reflect (MR), which provides a FREE version that can be used to image and restore partitions or drives together.

    What I recommend is the following:
    (1) download and install Macrium reflect (MR)
    (2) run M. and choose the option: "Create an image of the partition (s) required to backup and restore Windows" to write a full backup to an external drive or USB key
    (3) use the option to create a CD or a USB startup key

    NOW, you have the means to restore a full system that works for the external hard drive or USB key in a few minutes.
    ---------------------------------
    2: System reserved for resizing:
    There is a small partition on the HDD with Win7 preinstalled machines known as system reserved.  It is something known as the boot loader code.  There is 100 MB format: all that is necessary for Win7.  But Win10 needs 350 MB and, in some cases, is NOT able to resize it on its own.  IF this happens, you must manually use a partitioning tool to resize it yourself.
    ---------------------------------
    3: use a different approach to upgrade:
    Windows Update is the simpler, but less reliable, way to do the upgrade from Win10.  A much better and more reliable way is to use Microsoft Media creation tool: http://windows.microsoft.com/en-us/windows-10/media-creation-tool-install?ocid=ms_wol_win10 choose the upgrade this option now PC.

    After all this, you know that MS install drivers with only the most basic features.  Given that HP does not have drivers for your PC Win10, this limited functionality is the best you're going to get.  HP does not actively write new drivers from Win10 for the old PC Win7.  To keep all the features of your PC, your best shot is NOT to upgrade to Win10.
    ---------------------------------
    4: be prepared to clean-install:
    If you do all this, and after the upgrade, your PC works partially, this means that the upgrade is not well and stuff is still there the previous OS corrupt the functionality of Win10.

    You MIGHT be able to solve the problem in fact a clean install of Win10. Problem is that, often, a clean-install does not recognize prior activation, even if it should. So, before doing the upgrade, follow these instructions on the community forums Win10 on creating a genuineticket.xml file: http://www.tenforums.com/tutorials/23354-clean-install-windows-10-directly-without-having-upgrade-first.html

    You need more later to activate your pc Win10 after the installation of clean.

    Good luck

  • Why is upgrade Windows 10 - not Dell Vostro 3550 on the list of Dell?

    I found this list on the Dell site that tells you if they tested a particular model for its ability to be upgraded to Windows 10.   The Dell Vostro 3550 is not on the list of 20 Vostro models, some wearing low model numbers, some superiors.   They will never test it?

    If you try to upgrade, windows 10 copies files and then in the 2nd of three main sections of the upgrade (where you have this big circle in the middle of the screen), it just goes to a blank screen and then ceases all activity of the disc, and it becomes well hung.   Of course, now the machine think operating system is win 10 and you cannot return to a recovery point 7 win.  If you lost all of your data and applications and restore the image and then install the windows 7 208 updates and it takes like 8 hours total.

    Looks like a similar problem that people with Vostro ranging from win 7 to win 8.   Why not fix it.

    Also, I fell into the same rabbit hole. But I realized quickly that it was a video problem and I hung on an alternative to the unit's LCD monitor... worked just fine, there has been able to do the update of bio and play with the drivers.

    There is no need to "reserve" anything.  This is purely marketing share MS to "encourage" users upgrade.  They will be happy to pass any OS eligible in the first year for free, and it will remain free for the life of the device when it was released on July 29

    There will be some ISO available when win 10 is out July 29
