Hi,

I read in some articles.

Please let us know, how it is recommended to install Windows 11 after removing appraiserres.dll?

What is this file for?

Moreover, please share correct way to install Windows 11 in any unsupported hardware by removing appraiserres.dll file.

With Regards

Windows 11 can be installed in any unsupported hardware by removing appraiserres.dll file.....

What is this file for?
This is the file that checks for Windows 11 compatibility (secure boot, TPM, CPU, etc.) when trying to upgrade from windows 10 to Windows 11. When deleted all compatibility checks are skipped. Example screenshots of how to do so in this post....

This is how I removed that .dll file whilst upgrading to Windows 11.

Download latest Windows 11 ISO and mount it (open with Windows Explorer). It will create a virtual DVD drive where you see the contents of the ISO. Run Setup, it will count to 100% and then show the first screen. Before proceeding open This PC and open C: then open the Windows.~BT folder, then the sources folder. Delete the file appreserres.dll Now check had been bypassed and you can proceed with the upgrade.

If you want to format and do a clean installation instead, the easiest way is to create a hybrid installation media. This is the same as a Windows 10 USB Flash drive, but with a specific file replaced. Download the Windows 10 ISO and create a USB Flash drive. Now download the Windows 11 ISO (make sure you download the same language), mount it and copy the file install.wim (or install.esd) from the sources folder into the sources folder of the USB Flash drive replacing it. Boot the target computer with this hybrid USB Flash drive. There will be no compatibility check, just proceed with the installation.

Your explanation goes a little over my head. I have no problem finding the appraiser file in the ISO but I can't delete it or change the read only status. I assume that your method resolves that problem but I don't understand how to get to the windows.-bt folder. Perhaps you could help me understand how to delete the dll.

I was referring to the appraiserres.dll file in the setup cache, in the folder C:\Windows.~BT\sources You should be able to delete that. I assume you are doing that from an administrator account. A standard user cannot do that.

PS: The Windows.~BT folder might be hidden. Change the Windows Explorer settings s you can see the hidden files.

Are you running the ISO from the win 10 drive? I have been running from a USB drive

The hack with the appraiserres.dll file applies only for upgrading Windows 10 to 11 or upgrading an old Windows 11 build to the newer build. For clean installation you need to either patch the Registry (if you start your computer with the Windows 11 USB Flash drive) or create a hybrid installation media. The latter is a Windows 10 USB Flash drive with the file \sources\install.wim replaced from the Windows 11 ISO. I find the hybrid installation media method much easier to install Windows 11 on non-compliant systems. You can even create a Legacy BIOS (MBR) Flash drive to install on systems without UEFI such as my test laptop (see my 1st PC specs)

easy to just copy the mounted iso files to a desktop folder, delete the dll, then run setup, and tell it not to check for updates.
That is what I did following the video in my thread. I did this while running win10.

Also Ventoy or Rufus will let you skip compatibility check, like you boot from a USB drive, no need for windows to be running.
No manual editing of files, etc...

link mentioning how it is bypassing the hardware checks, longpanda is the Ventoy developer.

I have not done this using Ventoy yet, but it may be just silently done, no user interaction.

I was successful with Spapakon's method once I understood where everything needed to be. I looked into Rufus but couldn't figure out which version I needed to download. ver. 3.17 doesn't have the feature and there is long list of 3.16 versions. I'm good but thanks. I did this on my wife's computer without her knowledge and it worked fine. She couldn't tell she was on a new version of Windows.

For the company computers I created a win 11 drive on a compatible computer, loaded our sofrware on it and cloned it onto each system just needing to change the validation key for each one. Much faster than a new installation but not for everybody since it requires having at least one compatible machine. I have two compatible desktops and 2 compatible laptops so the process of bringing the older computers up to grade was quick and painless.

You don't need a compatible computer. Just install Windows 11 on any computer and clone the disk for the others. If they aren't totally different (such as Intel vs AMD or AHCI vs IDE), Windows should find most drivers and boot successfully without the dreaded BSOD of older Windows versions when you tried to boot the disk on another computer.

You don't need a compatible computer. Just install Windows 11 on any computer and clone the disk for the others. If they aren't totally different (such as Intel vs AMD or AHCI vs IDE), Windows should find most drivers and boot successfully without the dreaded BSOD of older Windows versions when you tried to boot the disk on another computer.
The upgrade I did was pretty fast. Not a single issue, no BSOD, no quitting, no nothing. Helps tremendously to be using SSD on older hardware

We upgrade old computers with SSD in our Service. Most people prefer that than buying a new computer which won't really need for what they do.

The hack with the appraiserres.dll file applies only for upgrading Windows 10 to 11 or upgrading an old Windows 11 build to the newer build. For clean installation you need to either patch the Registry (if you start your computer with the Windows 11 USB Flash drive) or create a hybrid installation media. The latter is a Windows 10 USB Flash drive with the file \sources\install.wim replaced from the Windows 11 ISO. I find the hybrid installation media method much easier to install Windows 11 on non-compliant systems. You can even create a Legacy BIOS (MBR) Flash drive to install on systems without UEFI such as my test laptop (see my 1st PC specs)
Not so, using the official MS Windows 11 Installation media and creating a Bootable USB drive and removing the appraiserres.dll file from with in the 'Sources' folder. It is possible to refresh Windows 11 Pro from running setup from the USB Drive while logged in windows. The refresh is achieved without losing any files or installed programs and takes about 1 hour. I have successfully done this with the latest 21H2 build of Windows 11.

I'm running the latest Dev build of Windows 11 on an unsupported laptop. There are frequent upgrades to the next build through Windows Update, aka a Feature Update. This also uses appraiserres.dll and initially fails saying 'this PC doesn't meet the specs'. Windows Update then reports this as a failed update with a 'Retry' button.

Deleting appraiserres.dll from C:\$Windows.~BT\Sources is not sufficient to get the update to complete, Windows Update reports 'something went wrong' if appraiserres.dll is missing. I have to replace it with a dummy file named appraiserres.dll then click Retry before Windows Update will complete the upgrade properly.

Windows 11

In this video, i will upgrade Windows 10 to Windows 11 on unsupported computer hardware. Although Windows 11 has a higher system requirement, you may still be able to perform an upgrade on an unsupported computer. The Windows setup has an “appraiser” service that checks to see if your computer meets the minimum hardware requirements for that version. It’s possible to replace the appraiserres.dll file in the Windows 11 setup with one from an older build of Windows 10. In order to replace the Windows 11 DLL with one from Windows 10, you’ll actually need the setup files for Windows 10.

I did not mean 'Deleting appraiserres.dll from C:\$Windows.~BT\Sources', I meant removing the appraiserres.dll file from the Sources Folder of the Install Media USB Stick and kicking of the setup process from the USB drive while in windows, (not booting up with the drive). Works every time and have had no failed installations.

I'm curious, when you say unsupported, what hardware/software features are missing on your laptop?

It has no TPM, its Celeron N2930 is an unsupported processor, and it's using a Legacy bios install.
