Microsoft sells the same underlying Windows and Office software under several very different license types — and within Windows itself, several different editions. Understanding which type and edition you have, and what you're allowed to do with it, saves confusion and keeps you compliant. Here's the plain-English breakdown of everything: Essential vs Professional editions, and Retail vs OEM vs Volume license types.
Windows Essential vs Professional: What's the Difference?
"Essential" isn't an official current Windows edition name — it's a term people commonly search for when they actually mean Windows Home vs Windows Pro (Professional), or occasionally an older "Starter"/"Basic" edition from older Windows versions. Windows Home (sometimes called the entry-level or "essential" edition) covers everyday use: web browsing, office work, media. Windows Professional adds features Home lacks entirely: BitLocker device encryption, Remote Desktop (both hosting and connecting), Group Policy Management, the ability to join a Windows domain or Azure AD, Hyper-V virtualization, and support for higher RAM ceilings on certain configurations. If you work with company networks, need remote access into your PC, or want built-in encryption, you need Pro — Home cannot be upgraded to unlock these features without a separate Pro license or product key.
Retail (FPP) Licenses
Full Packaged Product licenses are the most flexible license type. You can transfer a Retail Windows license to a different PC once it's been removed from the original machine. They're the most expensive type — Windows 11 Pro Retail is ~₹14,999 from Microsoft directly. Our reseller keys fall under this category.
OEM Licenses
Original Equipment Manufacturer licenses come pre-installed on PCs and laptops. They're tied permanently to the hardware they ship with — if your motherboard dies, technically the license dies with it. OEM Windows licenses cannot be transferred to a new PC. They're cheaper because of this restriction.
What Is a Volume License (VL) Key?
A Volume License (VL) key is a bulk-activation license type sold to businesses, schools, and government entities rather than individual consumers, typically through Microsoft's Volume Licensing Service Center or an authorized Licensing Solution Provider. Instead of one key per device, a single Multiple Activation Key (MAK) can activate hundreds of machines, or a Key Management Service (KMS) key can activate devices against an internal company server that re-validates periodically. VL keys are licensed per-organization under a Volume Licensing Agreement, not sold as standalone retail products — which is why you generally cannot buy a genuine VL key as an individual consumer the way you can a Retail or OEM key.
VL vs Retail: Which Should You Buy?
For a single personal PC, Retail is almost always the right choice over VL: Retail keys are designed for individual ownership, are fully transferable once to a new PC, and are sold as standalone products. VL keys are licensed under organization-wide agreements, are not intended for individual resale, and typically require proof of organizational eligibility to obtain legitimately. If you're comparing the two because a VL-looking key was offered to you far below Retail price outside of a proper business licensing channel, treat that as a red flag on legitimacy rather than a bargain — see our section on Volume Licensing above for what a genuine VL key actually requires.
Windows License Types at a Glance
Quick reference for the three core license types covered above: Retail (FPP) — sold to individuals, transferable once, most expensive, most flexible. OEM — bundled with new hardware, permanently tied to that device, cannot transfer, cheapest. Volume (VL/MAK/KMS) — licensed to organizations under a volume agreement, activates many devices, not intended for individual purchase. Within any of these, you separately choose an edition — Home vs Pro (Professional) — based on the features you need, as covered above.
Which Type Should You Buy?
For personal use on a single PC: Retail keys from a trusted reseller are your best bet — genuine, flexible, and much cheaper than direct from Microsoft. For a business with 5+ PCs: consider Microsoft's own volume licensing portal for proper business compliance rather than sourcing VL keys through a reseller.
Frequently Asked Questions
What is the difference between Windows Essential and Professional?
"Essential" typically refers to Windows Home (the entry-level edition), while Professional (Pro) adds BitLocker encryption, Remote Desktop hosting, domain/Azure AD join, Group Policy, and Hyper-V — features Home doesn't include at all.
What is a volume license (VL) key?
A VL key is a bulk-activation license sold to organizations under a Volume Licensing Agreement, using either a Multiple Activation Key (MAK) for many devices or a KMS key that activates against an internal company server — it isn't sold as an individual retail product.
Is VL or Retail better for personal use?
Retail is the right choice for personal, single-PC use. VL keys are licensed to organizations, not individuals, and a VL-style key offered far below Retail price outside a proper business channel is a red flag, not a discount.
What are the different types of Windows licenses?
The three core types are Retail (FPP, sold to individuals, transferable once), OEM (bundled with hardware, non-transferable), and Volume/VL (licensed to organizations, activates many devices). Each type is separate from the edition you choose, such as Home or Professional.
Can I upgrade from Windows Home to Professional using a Retail key?
Yes. Go to Settings → System → Activation → Change product key, and enter a genuine Windows 11 Pro Retail key. This unlocks all Professional-only features without needing to reinstall Windows.
