How do I do a fresh install of Windows 10 if it is a free upgrade from Windows 8/8.1? - Page 2

post #11 of 20
Windows 10 has a built in reset that basically does a fresh reinstall... with the options of either keeping some files or deleting and reformatting all drives.

That's not really comparable to a true clean install. It retains drivers,at the very least.

Well as I said "basically"... I did not use the word "exactly". Depending on the why he is doing the reset the built in reset could be all he needs.

Have you managed to fix this? I am planning on following Oubadah's advice and skipping everything involving the key.

Nope, Basically told by MS I have to buy a new key or put up the Nag that pops up a little warning every 2 hours.

In case of a board failure, you can call the activation line and explain that it is a replacement board due to defect. You can of course lie about this, but that is a completely different discussion.

I had to do this when replacing a failed mobo in my Dell PE2900 server. Its running on an Win10 installed using a win7 key so it's considered a retail upgrade. If you are not attached to a windows live account you are hosed.

This might help someone.

I think it was a success. I didn't realize that my HDD was an SSHD. Now, I am thinking of replacing my 500 GB HDD on my PS4. I just need to retrieve some music files I forgot. Is it safe to just plug the SSHD into my computer and take the files from thre?

How should I format the SSHD for the PS4, if at all?
post #17 of 20
Just like a normal drive, the harddrive itself will identify what files the PS4 uses often and move them to the SSD part of the drive.

I cannot seem to access my SSHD. When I plug it in, it doesn't show. When I restart my computer, it seemed like the computer was booting off it. What can I do to access the storage of the SSHD without purchasing a USB SATA connector?

Edit: Maybe I should put it back in my laptop and retrieve the files from there.
post #19 of 20
The way I do it seems to work great for my mutiple machines that I change hardware in often. If you change hardware, your Win 10 actiavation won't work most of the time. As long as you have the anniversary OS update, you can link your specific Win 10 key to your Microsoft account. Once that is done, reinstall Windows and go to Activation. There will be a list of all machine IDs that you have linked. Select the one you want to use and then pick the option for Hardware change. Windows will then hit MIcrosoft's activation service and will reset the unique hardware ID linked to that particular license.

Note that you can only reset the unique hardware ID connected to that Win 10 key a certain amount of times within a given time period. This shouldn't be a big issue for 99% of people, but it is an inconvience for people who do a lot of hardware reviews and such.

My Windows 10 is from a Windows 8 upgrade to a Windows 7 Ultimate full license. I did a fresh install of the Creator Update of Windows 10 while also upgrading to a new video card. I found that you can now tie your Windows 10 install to your Micro$oft account. I followed this process here and had no problems activating my install. it automatically activated. I did not enter a product key during the initial install:
