Windows 11 Upgrade TPM Module 1.2 - 2.0

Hi need some help here please. I am aware this year Microsoft will be stopping support for Windows 10 which I have quite enjoyed myself, I am planning to upgrade to Windows 11 at some stage, currently my Dell XPS 15 9550 model won't upgrade to Windows 11 due to the out dated TPM module. My current TPM version is 1.2 but I need to upgrade it to 2.0 to allow my laptop to run Windows 11. Everything else like CPU, RAM, HDD space etc is OK. Is it possible for me to upgrade my TPM from 1.2 to 2.0. I have downloaded the TPM update module software from the Dell website and when I try to run it, I get an error saying "your TPM is owned". Thank you.

To update your TPM, go to this page https://www.dell.com/support/home/en-us/drivers/driversdetails?driverid=rf87d&oscode=wt64a&productcode=xps-15-9550-laptop .  Download the firmware update utility, scroll down and expand Installation instructions.  Follow those steps to disable auto provisioning in Windows, and clear TPM in BIOS before running the firmware update.

Even with an updated TPM, the 6th gen Core i CPU does not have support for Windows 11, so you'll need to bypass the CPU/TPM check to get it installed.

I am sure my CPU which is a i7 Intel has passed the mark for Windows 11, looks like just the TPM module is the problem here. I ran a Windows 11 Upgrade check and the CPU passed.

Windows 11 support requires an 8th gen i7.  You have a 6th, so -- no, the CPU is not supported by Windows 11, unless the 9550 model number you supplied is not correct.

I think the current check for CPU support bypasses the requirement.

I just ran the CPU ID software on my Dell XPS 15 9550 and the CPU is a Intel Core i7 6700HQ Skylake.

Is there any way I can do a test to see whether this CPU is ok to accept Windows 11.

So is MS actually closing down Windows 10 or will they still keep supporting it and us users just need to pay for a yearly subscription for the updates and support

Ok update here, I just did a Windows 11 PC Health Check and your correct the CPU isn't compatible for Windows 11, damm what to do. Again I don't want to bypass it as I don't want the current CPU to get too hot and start to throttle.

You don't have a choice -- this system cannot be fitted with a CPU that supports Windows 11 officially.

Your system will take Win 11 24H2 without problem.  Head to MS and download the latest Win 11 ISO.  Then, create a USB installer using RUFUS.  For the bypass options, only select to bypass MS account.  That will allow you to install Windows 11 with a local account.  Any MS account can be added later.

Just remember do not connect to internet and you will see option to select I don't have internet.  The installation process will then give you option to create User Name and Password, instead of using Microsoft account. 

I was able to install Win 11 with TPM 1.2 without using any hardware bypass.

OK many thanks for the update, I will give it a go sometime. 

Questions

1. I have already created a bootable USB thumb drive

2. Does the bypass option come up during the installation process.

3. Suppose during the installation process I will need to turn off my Wi-Fi settings and add my Microsoft account later on to it. 

4. Do I really need to create a new user name and password since I've already have one 

5. Finally on a more serious note how do you compare it to Windows 10 and is it upgrade really well worth it 

I did see a guy on YouTube install Windows 11 and bypassed things but he used some DOS command to do the installation and was using some server install command, though it didn't actually install the server edition.

There are many different ways to bypass and install Windows 11.  The method I show you is to use RUFUS to create USB installer from Win 11 ISO.

When run RUFUS, it will offer a menu with bypass options.  Select only the option to bypass MS account.  To prepare the system hardware for installation, reset BIOS to default.  Then, verify UEFI is ON, Secure Boot is ON, and TPM is ON.  For desktop, ethernet cable needs to be unplugged, for laptop no need to connect to wifi network.  The installation will give option to create local account.  After installation is complete and the Windows is activate, you can add MS account using your MS account.

If you do not want local account, then select option to bypass CPU, TPM during RUFUS setup.  It will depend on each user preference.

Some users being forced to migrate to Windows 11, while some others prefer to upgrade.  Whichever the case, I suggest to install on a new, spare drive.  That way, you can reverse back to old system if you don't like Win 11.
