You can use a utility like RW Everything to retrieve the license key stored in the ACPI BIOS table:
If the key isn't there, see above -- contact the seller to find out why. Chances are it shipped to them from Dell without a license key.
The currency code for Taka is BDT, and the currency symbol is Tk.
This is not the free windows keys for Bangladesh forum.
The site you reference DOES NOT SELL WITH WINDOWS 10 they CLEARLY STATE
If there is no COA key then you may need to check for the Key in Bios.
Windows 10 will install without a key and then activate based on the Key in Bios or on the COA. But you have to go online at least every 180 days to keep it active.
Its not even clear that you own a Legitimate Dell. More like a Knockoff.
The service Tag would show configuration and other specs.
Operating System for the DELL Inspiron 15 5567 is
Windows 10 Home
Windows 10 Pro
Which means that a Legit Windows 10 DVD from anywhere should reinstall without a key IF IT HAD one from DELL.
You cannot Activate unless you get ONLINE and touch microsoft at least one time.
There are no more permanent Offline Activations.

So what does that free-DOS means as you saw it from my reseller's website? And I used that tool of ShowKeyPlus was in my laptop it says at OEM Key section that "OEM key not present in firmware".
So I don't know how come my Laptop got shipped from Dell US to Bangladesh without an OS? Whats with Dell then about this matter? And as a consumer I have rights to get OS right? As I didn't purchase this laptop from the sky with free money!!!
And if anyone needs my service tag for confirmation of anything you can simply ask me.
Dell does not Export to Bangladesh. Free dos means you NEVER HAD legit windows. The referenced site is not an authorized Dell Reseller.
It is expressly forbidden to export DELL US Laptops with windows.
The U.S. export regulations restrict imports and exports to international destinations without a U.S. Government authorization (called "license").
You do not have "rights" from the U.S. in Bangladesh.
Note here is the difference in price including Windows makes. Without Microsoft’s operating system the final laptop price is $250 less. The n Series is a Dell product line that does not ship with a pre-installed version of Microsoft Windows. DELL does not ship computers without an operating system Dell instead ships these systems with the FREE DOS operating system. This has been the case since 2002.
This is not the Free windows 10 for Bangladesh forum.
Free DOS means the system comes from your reseller with a free DOS workalike OS - it does not include Windows.
Dell DOES sell systems without operating systems, if the resellers order them that way. The rules for shipment vary by location -- some markets preclude shipping Windows with new systems. At any rate, the rest of your questions are best directed toward the reseller. However, if you want Windows, you're going to have to purchase a full license for it, since it's clear now the system did not come from your reseller with Windows included.
So now the only way to get Windows in my laptop is to purchase it? Because my laptop didn't come with Windows installed on it so now Dell has nothing to do with my laptop nor they can give me free windows with license right?
Well if that's the case then, Windows is quite expensive so is there any way to use windows freely. And I have asked earlier that if anyone could give me an OEM of their laptop windows so that I can use it, anyone?
The system did not ship with Windows, so Dell cannot provide it. And OEM licenses require the product key that's embedded on the board when the system is shipped with Windows, so that won't help, either.
You need to purchase a license for Windows. If you're looking for a free OS to use, there are any number of variants of Linux that are completely free of charge. Windows however, is not.
Ubuntu 16.04.4 LTS
UEFI Secure Boot will need to be OFF and CSM ON for OS other than Windows. Knoppix is one of the easier ones to use without actually having to install it to get going.
If you do not have an optical drive you will need to make a USB installer.
