One of the system requirements of Windows 11 is that your computer has TPM version 2.0. See how you can check if you have TPM or not.
What is TPM?
The Trusted Platform Module (TPM - Reliable platform unit) is a device security that can be integrated into the motherboard of your computer but can also be installed afterwards, if of course there is a suitable slot.
Computers from 2016 onwards have the largest percentage of TPM. This device also offers unique encryption codes on operating systems such as Windows 10, is used in functions such as BitLocker, to encrypt and decrypt the hard disk.
There are several versions of TPM but the one Windows 11 requires is 2.0. When Windows 8 was first released, it required version 1.2 for BitLocker and if you didn't have it the problem was solved with corresponding software.
See if you have a TPM and if so, which version
1st way: Press Win + R at the same time and in the Run window that appears type tpm. msc and press Enter or do click to OK.
But in this case you may just not have it enabled by the BIOS or UEFI. You need to enter the BIOS of the computer and look for where the TPM is mentioned and make it Enable.
If you have and it is activated you will see something like this:
Στο παρακάτω παράδειγμα, η κατάσταση είναι: \”Το TPM είναι έτοιμο για χρήση\”. Και οι information κατασκευαστή είναι η έχει την έκδοση 2.0. Αυτό σημαίνει ότι το PC είναι κατάλληλο για την εκτέλεση των Windows 11.
2 Way: You can find out if you have TPM or not through device management. Right-click the Start button, and then click \ "Device Manager \".
Once Device Manager is open, scroll down and click on \ "Security devices" (or Security devices, if you have English) to expand the menu and see if there are any TPM entries.
3 Way: Use the command line. Open a command prompt as an administrator and type:
wmic /namespace:\\\\root\\cimv2\\security\\microsofttpm path win32_tpm get * /format:textvaluelist.xsl
If you have TPM and it is enabled it should return the TRUE value and you can see the version where it says SpecVersion.
Of course you can easily enter the BIOS or UEFI and see if you have TPM, but it is not as easy as the above methods. You can also use it Windows PC Health Check application to make sure your system supports Windows 11.
