A Beginner’s Guide to GPT vs MBR and How to find your Windows 10 Product Key


If you’re a beginner when it comes to computer terminology, the acronyms GPT and MBR can be confusing. What do they stand for? What’s the difference between them? And more importantly, which one should you use? We’ll answer all of those questions and more in this blog post. We’ll also show you how to find your Windows 10 product key so that you can activate your operating system.

GPT vs MBR: What’s the Difference?

GPT is an abbreviation for GUID Partition Table, and MBR is an abbreviation for Master Boot Record. Both are ways of storing partition information on a hard drive. GPT is the newer standard, while MBR is the older standard. 

GPT vs MBR is a common question when it comes to computer hard drives. GPT or GUID Partition Table is a standard for partition table layout on a physical hard disc. MBR, or Master Boot Record, is a legacy standard that was used for the layout of the partition table on early hard drives. GPT is now the preferred standard, as it offers several advantages over MBR. First, GPT allows for a larger number of partitions on a drive. MBR is limited to four primary partitions, while GPT supports up to 128. This can be useful if you need to create multiple partitions for different purposes, such as separating your operating system from your personal data. 

GPT also offers better protection against data corruption and malicious attacks. MBR uses a single sector to store its partition table, which makes it vulnerable to corruption if that sector becomes damaged. GPT protects against this by storing multiple copies of the partition table in different locations on the drive. Finally, GPT drives can be larger than MBR drives. MBR has a 2TB size limit, while GPT supports drives up to 8EB (Exabytes). If you need more storage space than MBR allows, GPT is the way to go.

Whether you should use GPT or MBR for your drive depends on your needs. If you need more than four partitions or want better protection against data loss, GPT is the way to go. However, if you’re using an older system that doesn’t support GPT or doesn’t need any of its benefits, MBR will work just fine.

The main difference between GPT and MBR is that GPT supports drives larger than 2TB, while MBR does not. GPT also supports more partitions than MBR (up to 128 vs 4). As a result, if you have a large hard drive or multiple partitions, GPT is the way to go. 

Converting Between GPT and MBR

If you have an older computer with a BIOS that doesn’t support GPT, you’ll need to convert your drive from GPT to MBR in order for it to work properly. Thankfully, this process is relatively simple and can be done using some free software like AOMEI Partition Assistant Standard Edition. 

Where I Find Windows 10 Product Key?

Windows 10 Product Keys are very important. By default, Windows 10 automatically activates itself when it is installed. Windows 10 will automatically connect to the Microsoft activation servers and activate itself without user intervention. However, some users may want to manually activate Windows 10. In order for Windows 10 to be manually activated, however, a product key is required. Product keys are usually found on the Windows installation media or in the confirmation email that was sent when Windows was purchased. If the product key cannot be located, there are a few ways to find it. The first way is to use a third-party key finder program. These programs scan the Windows registry and locate the product key. 

The second way is to use Windows PowerShell. Windows PowerShell is a command line utility that allows users to perform various tasks on their computers. To find the Windows 10 product key using PowerShell, open PowerShell and run the following command: Get-Windows Product Key. This will result in the return of the Windows 10 product key. Finally, another way to find the Windows 10 product key is by looking in the registry directly. The Windows registry is a database that stores information about all of your computer’s files and settings. To view the Windows registry, open the Run dialog box (press Windows + R on your keyboard) and type Regedit into the box. It is recommended that before making any changes, make a backup of your registry.

Your product key is a 25-character code that’s used to activate Windows 10. It looks something like this:  PRODUCT KEY: XXXXX-XXXXX-XXXXX-XXXXX-XXXXX. This code is usually on a sticker on your computer, or in the documentation that came with it. If you can’t find it there, you can use a free tool like Product Key to retrieve it from the registry. 


In conclusion, GPT vs MBR is mainly a matter of preference. If you have a large hard drive or multiple partitions, GPT is the way to go. Otherwise, either option will work fine. Be sure to convert your hard drive from GPT to MBR if your computer’s BIOS doesn’t support GPT. Finally, if you need help finding your Windows 10 product key, there are plenty of free tools out there that can help you retrieve it. Thanks for reading!
