The Difference Between GPT and MBR and How to Find Your Windows 10 Product Key

When you’re installing a new operating system or formatting your hard drive, you’ll need to know the difference between GPT and MBR. GPT, or GUID Partition Table, is a more modern standard that’s slowly replacing MBR, or Master Boot Record. Keep reading to learn more about the difference between GPT and MBR as well as how to find your Windows 10 product key.

GPT vs MBR: What’s the Difference? 

GPT is a newer standard that’s gradually replacing MBR. It’s more flexible and allows for larger drive sizes. MBR is the older standard and can only handle drive sizes up to 2TB. Both GPT and MBR use a bootloader to start your operating system. 

GPT vs MBR is a debate that has been going on for years now. GPT is the newer standard and is slowly becoming more popular, but MBR is still widely used. So, what’s the difference? GPT stands for GUID Partition Table. It’s a newer standard that uses 64-bit addressing to allow for better compatibility with newer hardware. MBR, on the other hand, stands for Master Boot Record. It’s the traditional partitioning method and is limited to 2TB of storage. GPT is gradually becoming more popular as it offers more flexibility and scalability, but MBR is still widely used due to its simplicity and backward compatibility.

If you’re not sure which partition table you have, check in your BIOS settings. To do this, restart your computer and look for a message that tells you which key to press to enter BIOS settings. Once you’re in the BIOS menu, look for a tab or section called “Boot.” In this tab or section, you should see either “GPT” or “MBR” listed next to your hard drive. 

How to Find Your Windows 10 Product Key 

If you’re planning on reinstalling Windows 10, you’ll need to find your product key first. Your product key is a 25-character code that you can use to activate Windows 10. You can find it in the confirmation email you received after buying Windows 10 or on the sticker attached to your computer if you bought it pre-installed. 

If you can’t find your product key, there are a few other ways to get it. If you installed Windows 10 from an Anniversary Update or Creators Update ISO file, the product key should be stored in the registry. You can also use third-party software like NirSoft’s Product Key tool to recover lost product keys from Microsoft Office, SQL Server, Adobe Acrobat, and VMware Workstation installations. 

Recovering lost product keys from unbootable Windows installations is also possible with utilities like Magical Jelly Bean Key finder and Laze soft Recovery Suite Home Edition—but only if those installations were activated with retail keys in the first place. If they were activated with OEM keys provided by an original equipment manufacturer like Dell or HP, then those keys cannot be recovered because they are embedded into BIOS/UEFI firmware and aren’t stored anywhere on disk. You would need special hardware debuggers for that—and even then it wouldn’t be easy or guaranteed footage of success hospital ward if possible at all except for very experienced developers familiar with low-level PC internals. Conclusion: In conclusion, GTP is gradually taking over from MRB because it supports larger drives however MRB is still being used too. If installing Windows 10, ensure you have your 25-character product key ready beforehand!


GPT vs MBR GPT is the more modern standard and is required for booting Windows 10 on a UEFI system. GPT also supports larger hard drives than MBR. Test your computer to see which it uses. If you’re not sure, GPT is probably what you want. To find your product key, you’ll need to know which type of Windows 10 license you have. If you installed Windows 10 yourself, then you should have a digital license tied to your Microsoft account. 

If you have a retail license, then it will be a 25-character product key that you can find by going to Settings > Update & Security > Activation. If you purchased a new PC with Windows 10 pre-installed, then your product key will be on a sticker on the side or back of your computer case. If your computer came with an OEM version of Windows 10, then your product key will be in the BIOS or UEFI firmware. You can use the Belarc Advisor tool to scan your computer and find your product key (as well as a lot of other useful information about your system). Once you have your product key, you can use it to activate Windows 10. You can do this by going to Settings > Update & Security > Activation and selecting Change Product Key. Enter your 25-character product key and follow the prompts to complete activation.
