Cannot Activate After Upgrade From OEM
Jul 31, 2015
I did the upgrade with the media creation tool - "Upgrade this PC" option and my Windows wasn't activated. Using the "Activate" button gets me a "Windows can't be activated. Try again later" message (I'm on Brazilian Portuguese language, so the actual English message may be a little different).
After some web searching, I tried a variety of slmgr commands that all return error messages saying I'm on a "non-core edition" and none of the slui options give any result (not even errors, they just don't do anything). Clicking on the error detail link on the activation page shows a blank popup.
Product key information shows *****- opposed to *****-XXXXX I've seem in many screenshots of other people having activation problems.
My previous OS was Windows 7 SP1 OEM that came shipped with the laptop and was never formatted (and the hardware was never changed). I kept my personal data while making the upgrade.
Another issue I'm having which I don't know if it is related or not to the activation problems, is that Window Update have tried and failed many many times to install package KB3074683.
For the record, the activation screen was different and I haven't received any message about the system not being activated before creating a Microsoft account in the XBox app (and I still log on the computer with my local account).
How to activate my Windows 10? I'd like to make a clean install but I'm afraid of doing so before my I get my license and not be able to roll back to Win7 if I can't activate it.

I upgraded from 8.1 (genuine Sony Vaio ) using the media creation upgrade option, it installed and activated to windows 10 pro.
I then used the same media creation tool to download the iso and used Rufus to put it onto a usb so that I could do a clean install.
I installed it and skipped the parts prompting for a product key, however once it loads up when I try to activate it states 0xC004C003 details section says the key has been blocked?
Have I missed something?

Last night I finally decided to backup all of my files on my Windows 7 desktop machine and wanted to do a clean install of Windows 10 (I had been wanting to reformat for a while, this seemed like a good time to do it). I noticed after starting the free activation of Windows 10 (through Windows Update) that it would only update to Windows 10, so I let it proceed.Once 10 finished and booted up, everything was great. At this point, I went into settings and chose to Reset this PC, and made sure to select only to remove files - not fully clean the drive.
After being stuck at only 2% for 4 hours, I decided to give up on the reset completing. I turned off my desktop, and then downloaded the Windows program that creates the installation on a USB drive from my laptop. Once completed I inserted the USB drive into my desktop and installed Windows 10 as a clean install without any issues.After all of this, I cannot activate my Windows 10. Is my only option to use my old Windows 7 installation/key to do another clean install, then go through the Windows 10 update again?

I recently upgraded my CPU, Motherboard, Ram, and HDD to SSD. I upgraded my genuine copy of windows 8.1 to windows 10 about 3 weeks prior. I didn't want to install windows 8 all over again only to then have to update to windows 10 right after. So I just cloned my HDD onto my SSD. It worked fine for a day, but now its telling me I need to activate windows.
What do I do, is there any way to activate without having to reinstall windows 8 then upgrade to windows 10? I know my windows 8 product key will not work.

I originally got win10 through the free upgrade from 8.1 and did the install that only replaces system files etc. Some things weren't working correctly such as the sleep function and I kept being unable to login due to the start menu and Cortana not starting, so I decided to do a reset of the OS.
I managed to reset and get a fresh install of win10 but now I can't get activation to work. I've run all the windows updates and tried the slmgr.vbs /ato command but it says my product key is blocked.

I've recently been trying to upgrade from Windows 7 to Windows 10. I have tried to use the installer provided by Microsoft but the installer hangs on Checking For Updates. This doesn't end and I cannot pass it. I cannot use windows update to get the update as it just keeps searching for hours on end. I have tried to install the OS from USB and click 'Upgrade the System' but the OS will not activate; I guess it does not count as upgrading my OS so the key is not registered.
I have tried following this (Windows 10 - Upgrade Installation) and I have downloaded the ISO stated in Step 6 using option 1 (Windows 10 ISO Download) but then when I get to Step 7 #8, the ISO does not have Setup.exe?

So i have 2 hard drives. one is an old one with windows 7 still on it, and the other was new with nothing on it. I took out the old one with windows 7 on it but didn't wipe it, and put in the new one. I installed windows 10 on the new one via bootable usb. Now windows says it can't activate. I've already downloaded 100gb of games and i REALLY don't want to do that again.
How can i get the new hdd to activate windows without wiping it? will the product key be the same for both versions? Can I update the old drive then swap it out with the new one and it be activated?

I have been an Insider since the very first Insider build was released. I had installed each and every build first being on the Slow ring and the on the Fast. I had upgraded from a genuine Windows 8.1 Pro.
When the final RTM build TH1 Professional 10240 was released to Insiders ahead of schedule, I readily installed it and my machine was permanently activated at that time. The product key used was a generic one ending in 3V66T. Many of you may be knowing this.
Today, in fact just now, I formatted my system partition and installed a clean copy of Windows 10 Pro from USB which I had created using the Microsoft Creation Tool. When the setup asked me for a product key, I entered the same generic key as stated above. But now when I go to the Settings, it says the key doesn't work and hence, my machine cannot be activated. I signed-in using my Microsoft account before using the PC.
What the heck! I am an Insider. And didn't expect this to happen. What should I do next? Would the machine get activated itself after some time?

I am eligible to use Office 365 Pro Plus through my University and was able to use it with no issues on Windows 7, but upon attempting to install the programs on Windows 10 I am unable to activate the programs through the Microsoft Activation Wizard. I consistently receive error code 0x8004FC12 and am unable to continue with the activation process.
I have run sfc /scannow and even did a fresh install of Windows 10 to no avail. I've also tried the quick repair and online repair options using Add/Remove Programs with no success and I keep getting the same error. Running as administrator also does not solve the issue.
From what I remember from installing on Windows 7, I did not even need to undergo the activation process and the programs worked perfectly after installation, so my guess is that the programs are unable to connect and validate my license for some reason. I have tried disabling antivirus programs but this did not work either. Office 365 Online clearly shows I have it activated on my Windows 10 installation but repeated attempts at reinstalling have not fixed the issue.

My computer's SSD failed, and I just bought a SSD and installed Windows 10 on it. However, it is not activated. I originally had Windows 7, then installed Windows 8 Pro, then upgraded to Windows 10. This is all legal.
However, I ran a BIOS product key checker on my computer, and it shows that I don't have a product key in my BIOS. Is there anything I can do?
This is also quite an old machine (from 2007), would it support BIOS product key?

I'm having the same issue and Option 3 in that tutorial is not working for me. Should I start a new thread?
Mouse Hover Makes Window Active - Enable - Windows 7 Forums
My situation: in Win7, I had the option checked to 'Activate window on mouse hover' and just upgraded to Win10, and having no delay before the window gets active.
I went into the registry and for
HKEY_CURRENT_USERControl PanelDesktop
UserPreferenceMask the value there after the upgrade is DF 7E 07 80 12 00 00 00
I changed this to the suggested: 9F 3E 07 80 12 00 00 00 and after logging back in, on hover, the window gets active but not focused - not what I'm looking for so I have left this value at DF...
for:
ActiveWndTrkTimeout
I changed the decimal value to 150 and still no delay. Even at 500, still no delay.

I just upgraded to Windows 10 from Win 7, and am having the following problem:
After sitting idle for several hours, the screensaver never activates and the display doesn't go into power save mode. I've tried numerous settings to resolve it, but with no luck so far. Currently the settings I'm using are the same as they were in Windows 7, where everything functioned correctly. These settings are:
Power options: High performance (modified)
HDD set not to turn off
USB selective suspend disabled
PCI Express link state power management disabled
Minimum CPU state 100%
Screensaver to activate after 15 minutes
Display to shut off after 30 minutes
These may not be the optimal settings, but they worked in Windows 7, and even using more restrictive power settings hasn't resolved the issue since the upgrade.

how to reactivate my copy of Windows 10 if I make hardware upgrades that would make me need to format my hard drive (Motherboard, CPU, etc.). In other words say if I need a new motherboard down the road and once it is installed and I cannot boot into windows, how would I get my copy of windows 10 back after I format all the old drivers and such off and reinstall windows? Would I have to then buy a whole new copy? The only thing I could think of would install my version of windows 7, activate it, then upgrade back up to 10.

I need to re-activate Windows after a hardware change and was wondering if I could purchase an OEM license and use the key it gives me to activate it? I'm aware that using an OEM key means there will be troubles upgrading in the future, however I don't plan on changes for quite some time. Bottom line: Could I buy an OEM Windows 10 and go into the store, activate it and have it work?

If I understood this : clearly, then does it mean that Windows will activate itself from some Windows activation servers that are somehow written into my hardware even if I do a clean install deleting everything in my Windows partition?
Also, since the built-in "Create a Recovery Drive" will take forever or display an error when ''Backup system files to the recovery drive' is checked", I'm trying to create an Installation media. But I'm stuck with which ISO I should download. Now, there's Windows 10, Windows 10 Single Language, Windows 10 Home, Windows 10 Home N. I'm running Windows 10 Home at the moment. Which was upgraded from Windows 8.1(I think there was ''Single Language'' written after "8.1", not sure though). Which Version should I download. And if I install the wrong version by chance, will Windows still activate after I find out and install the right version? Please clarify these.... I'm really looking forward to do a clean-install to get rid of all the errors and bugs with drivers and just start over.
*DETAILS: Windows 10 Home Build 10240 [Upgraded via free upgrade, had an OEM version of Windows 8.1 when first bought]

Windows is frustratingly taking up all of my time and I have tried everything google has to offer to try and fix it but it seems like no one has screwed up as much as I have on whatever forum.I'm trying to set my account to administrator because I can't install programs, change account settings, make any changes through CMD without getting the system error 5 access denied message and I can't set the administrator account through CMD either. I also don't have the permission to change anything in regedit and I can't even reset my pc because it requires an administrator password which I don't have, is not "nothing" nor is it administrator or admin or password and I can't change it through cmd either.I can't even access the administrator account because it is disabled and even with an elevated cmd I can't activate the "hidden" administrator account.

i got a brand new computer recently that came with windows 10. i had to reinstall it a few times because of issues i thought were related to the installation (plus the first attempt asked me for a key which i didn't have, the second one didn't). i didn't activate right away. i got two BSOD in 24 hours and thought it was my computer but found out online that it's windows 10's fault so i went to update windows. the update i got took so long it almost looked like a whole new installation though it said updating. when i came home i went to activate and got this message windows is not activated as your previous version of windows on this device was not activated prior to upgrade to windows 10 error code 0x803f7001.
i am nearly 100% positive that error wasn't there before the update. how the hell can i have a previous installation when this is an windows 10 oem computer?
