Can I upgrade from Windows 7 to Windows 11 using the official method?

Windows 11 Installation Assistant only supports upgrading from Windows 10 to Windows 11. That is why upgrading from Windows 7 to Windows 11 is more difficult as there is no direct way to do that.

Installing an update freezes at 51–99%. What’s wrong?

The time required to download and install updates will depend on the speed of your connection, your network settings and the size of the update file. If the installation has slowed down, try checking update availability one more time, or run Windows Update troubleshooter. To check for update availability, select Start > Settings> Update & Security > Check for updates.

How to Upgrade Windows 10 to Windows 11 on a Compatible Device and on a Computer Which is Not Supported?

All users of Windows 10 have been offered the opportunity to upgrade to Windows 11 for free since 5 October 2021. In today’s article, we will explore two methods of upgrading to Windows 11: one for compatible, and the other for incompatible desktop computers and laptops.

While trying to update to the latest version of Windows, many users had to face a compatibility error saying “This PC doesn’t currently meet all the system requirements for Windows 11”. This means that such computer doesn’t satisfy the requirements necessary to complete the upgrade and support the new features, as listed in Windows 11 hardware specifications.

As the Microsoft official website says, “If you see the warning that your device is incompatible with Windows 11 system requirements, the operating system cannot be upgraded”. If you are sure that your PC meets all the requirements, use the PC Health Check app to determine if your device is eligible to upgrade to Windows 11. Your device must be running Windows 10, version 2004 or later, to upgrade. Free updates are available through Windows Update in “Settings”. – “Update and Security”.

To find out if your computer is compatible with Windows 11, use the official Microsoft utility – PC Health Check. You can download the latest version of this program from the official website.

The official utility by Microsoft, PC Health Check

Run PC Health Check. After installation, the utility window opens to give you a brief overview of your computer’s condition.
You’ll be offered to check your PC for compatibility with the system requirements. Click “Check now”.
In a few seconds, you will see that your computer is fully compatible with Windows 11.
Another possible result is that your computer doesn’t currently meet the system requirements for the upgrade.

That is why I’m going to show you two ways of upgrading Windows 10 to Windows 11 – for compatible and incompatible devices.

Your device is compatible with Windows 11

If your device is compatible with Windows 11, do the following to upgrade:

Go to the special page in Microsoft’s official website and download Windows11 Installation Assistant. It will help us complete the upgrade.

Install the program and launch it. Accept the License Agreement. After that, the Windows 11 download will start. To accommodate the files for Windows 11, your computer should have at least 9 GB of free space.

The required files will be downloaded, prepared and installed automatically. When step 3 is complete, you’ll be suggested to reboot your computer so that the installation can be continued.
For some time, the screen will remain black while your computer is working on the updates, and it may have to restart several times.
After the final restart, you’ll see the sign-in screen, and when you log on, the operating system will get ready to start for the first time.
When all updates are installed, you’ll see Windows 11 desktop.

Your computer doesn’t meet the system requirements for Windows 11

Now it’s time for the second method you may use when your computer doesn’t meet the requirements for upgrade.

There are many ways to do it, and some may work on your specific computer, and some may not, so it all depends on many factors. Our team has selected two options that worked fine on all computers used for the testing, and seemed the easiest and safest to use.

With the help of Windows 11 Installation Assistant

Although the first option is not an official one, it still lets you upgrade to Windows 11 even if your computer is not compatible, as long as you use the officially provided tool, Windows 11 Installation Assistant.

Go to the special page in Microsoft’s official website and download Windows11 Installation Assistant.

Run Windows 11 Installation Assistant in compatibility mode for Windows 7. Right-click on the Installation Assistant file, Select “Properties” — “Compatibility”. Check the box for the option “Run this program in compatibility mode for” and select Windows 7 from the list of available operating systems. Click Apply/OK.

Running a program in compatibility mode for Windows 7

After that, Windows 11 Installation Assistant will run without checking hardware compatibility of your computer. However, it doesn’t mean that you’re safe from any issues or additional checkups at some later time. The most amusing thing here is that we’re actually using an official Microsoft tool. With all that, we should remember that the company has declined all responsibility for any problems that users may encounter while trying to install Windows 11 on incompatible computers.

With the help of Universal Media Creation Tool

For the second option, you’ll need a third-party software tool, which makes it absolutely unofficial. You are going to perform all these actions on your own responsibility. Nevertheless, it worked fine on all the computers involved in this test.

To upgrade your operating system in this way, you need to download Universal Media Creation Tool. With this utility, you’ll be able to upgrade to Windows 11 without checking the computer for compatibility. To get Universal Media Creation Tool, visit the corresponding page on GitHub. Click “Code” and choose “Download ZIP”.

Extract the archive to any folder and run the file “MediaCreationTool.bat” As a result, you may see the system warning from SmartScreen. If it happened, click “More info” and then “Run anyway”.

The PowerShell window appears, with a list of Windows 10 versions which can also be downloaded by using Universal Media Creation Tool.

In the MCT Version window, choose item 11 which stands for Windows 11.

Another menu with a list of actions appears.

To perform an automatic upgrade to Windows 11, choose the line “Auto Setup”. It will start MediaCreationTool and begin upgrading your operating system to Windows 11.

All these steps are performed automatically. When working on them, the computer will restart several times. When the updates are complete, you’ll get a freshly installed Windows 11.

This is the method for upgrading to Windows 11 automatically with Universal Media Creation Tool. What is more, in the folder containing this tool you can also find a file that can disable checking your computer for compatibility with Windows 11. It removes another file with the name “appraiserres.dll” and creates a registry branch that allows to install Windows 11 without TPM 2.0.

Open the folder “MCT” and select a file with the name “Skip_TPM_Check_on_Dynamic_Update_v1.cmd”. Right-click on it and choose “Run as Administrator”. After that, start Windows 11 Installation Assistant. It will upgrade the operating system, and do it without checking your computer for compatibility.

Conclusion

If you lost some files as a result of installing, reinstalling, updating or resetting Windows, you can bring them back with Hetman Partition Recovery.

Partition Recovery™ 4.9

The tool recovers data from any devices, regardless of the cause of data loss.
