Take in all the Florida Keys has to offer on this epic road trip. The roughly 100-mile (one-way) route island-hops along the southern rim of the Everglades and Florida Bay from Key Largo south to Key West. Featured stops celebrate all things Keys: fresh-caught seafood, old-school roadside attractions, and unspoiled state and national parks. Following these steps on a Windows operating system, you can determine whether your computer is 32-bit or 64-bit: Open System by clicking the Start button, right-clicking Computer, and then clicking Properties. Under System, you can view the system type. If your computer is running Windows XP, do the following: Click Start.
How to View the Product Key in Windows 10
The Windows 10 product key is a sequence of 25 letters and numbers divided into 5 groups of 5 characters each (ex: XXXXX-XXXXX-XXXXX-XXXXX-XXXXX) that is used to activate the 32-bit or 64-bit Windows 10 edition that you have installed.
OEM PCs store and encrypt the product key in the UEFI firmware chip. The product key is no longer on a COA sticker to help prevent theft. When you reset or install Windows 10, the product key will automatically be detected from the UEFI firmware chip, and will be used to activate.
When you install an Insider Preview or retail copy of Windows 10, you will need to enter it's product key during installation.
Windows 10 Enterprise does not require you to enter a product key during installation. You will have a free 90-day evaluation period before you must change the product key to be able to enter your volume license product key and activate.
This tutorial will show you how to view the installed and OEM product key in Windows 10.
Starting with Windows 10 Insider Preview Build 14371, you can link your Microsoft account to the Windows 10 digital license (formerly called digital entitlement) on your device. This can help you reactivate Windows using the Activation troubleshooter if you make a hardware change later, such as replacing the motherboard.
Starting in Windows 10 Insider Preview build 10565:
Device activation improvements: Microsoft has received a lot of feedback from Insiders on making it easier to activate Windows 10 on devices that take advantage of the free upgrade offer to genuine Windows by using existing Windows 7, Windows 8 or Windows 8.1 product keys. If you install this build of the Windows 10 Insider Preview on a PC and it doesn’t automatically activate, you can enter the product key from Windows 7, Windows 8 or Windows 8.1 used to activate the prior Windows version on the same device to activate Windows 10 by going to Settings > Update & security > Activation and selecting Change Product Key. If you do a clean install of Windows 10 by booting off the media, you can also enter the product key from prior Windows versions on qualifying devices during setup. Refer to the Insider Hub for more information on these activation improvements including requirements.
Can I reinstall Windows 10 on my computer after upgrading with free upgrade?
Once you’ve upgraded to Windows 10 using the free upgrade offer or Media Creation Tool on an activated Windows 7 or 8.1 PC, you will be able to reinstall, including a clean install, on the same device. You won’t need a product key for re-activations on the same hardware. If you make a meaningful change to your hardware, you may need to contact customer support to help with activation. You’ll also be able to create your own installation media like a USB drive or DVD, and use that to upgrade your device or reinstall after you’ve upgraded.
Here's How:
Installed Key = This is the product key that Windows is currently activated with.
OEM Key = This is the key stored in the UEFI firmware chip on the motherboard. This key will not always be the same as the installed key. For example, when the PC came with Windows 8.1 originally installed.

I am lazy at home and use password authentication for my home machines. I am ready to move to key based authentication. There are many options on the web on how to do this, including catting then sshing the key over, scping the key over directly, etc.
I am looking for the easiest and recommended way to copy a key over, hopefully there is a convenience wrapper somewhere in the Ubuntu ssh package?
I'm already aware on how to shut off password logins.

The ssh-copy-id
command (in the openssh-client package and installed by default) does exactly this:
copies the public key of your default identity (use -i identity_file
for other identities) to the remote host.
The default identity is your 'standard' ssh key. It consists of two files (public and private key) in your ~/.ssh
directory, normally named identity
, id_rsa
, id_dsa
, id_ecdsa
or id_ed25519
(and the same with .pub
), depending on the type of key. If you did not create more than one ssh key, you do not have to worry about specifying the identity, ssh-copy-id will just pick it automatically.
In case you do not have an identity, you can generate one with the tool ssh-keygen
.
In addition, if the server uses a port different from the default one (22
) you should use quotation marks in this way (source):
I like the answer from Marcel. I did not know this command. I've always been using what I had found on a SUN web site:
I thought to post it here still, because it is a good illustration of what can be achieved in shell code with the power of ssh
. But using the ssh-copy-id
is definitively a safer way to do it properly!
Note that if the folder .ssh
does not already exist, the above command will fail. In addition, it might be better when creating the file to set a minimum possible permission (basically read-write for owner only). Here is a more advanced command:
Graphical method
- Open Applications ▸ Passwords and Keys ▸ My Personal Keys.
- Select your key and then click Remote ▸ Configure Key for Secure Shell.
On Ubuntu you can fetch your keys from Launchpad:
Details:
- You need a Launchpad account so login or create an account
- After logging in, click the button next to SSH keys:
Paste the contents of your public key file in that field (including comment). Such a key looks like:
Here,
ssh-rsa
indicates that the key is a RSA key,AAAAB3Nza .... UyDOFDqJp
is the actual key andlekensteyn
is the comment.- Save the key by pressing Import Public Key
- If everything went well, your key should now be listed under SSH keys:
The package ssh-import-id
needs to be installed on the machine which needs to be accessed from remote. This package is installed together with the openssh-server
package as it's a recommended package for openssh-server
. After making sure that ssh-import-id
has been installed On the client machine, run:
This will download the public key from the Launchpad servers over HTTPS which protects you from MITM attacks.
On Ubuntu Lucid and before, you can accomplish the same with:
The echo
command is needed to get an extra newline after the line with the SSH key.
for custom port
-i switch defaults to ~/.ssh/id_rsa.pub, if you want another key, put the path of the key after -i
WARNING: If you did not write the -i it will copy all your keys found in ~/.ssh
ssh-copy-id
does exactly that. I am not sure why some of the other answers here add inaccurate information. The help shows the following:
I just tried the following on Ubuntu 18.04 client with a CentOS 7.6 server and it worked like a charm. The example shows using a custom port of 2222
, and specifying a public key at ~/.ssh/path-to-rsa.pub
Before running the command, I actually used the -n
switch at the end to do a dry run which confirmed that the command will work as intended. Once I confirmed it I ran the command again as above, without the -n
switch.
