how do i go about doing this? replace C:\$windows.~BT\sources\appraiserres.dll with a zero byte sized file with the same name.

replace C:\$windows.~BT\sources\appraiserres.dll with a zero byte sized file with the same name, how do i do this and please show what the file should look like, thanks in advance.

Why do you want to do that?

to be able to upgrade dev build 23493 to 23506. if there is a better way, please advice.

im using an unsupported pc.

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.

That's not quite what jestrada47 is asking. They don't want to upgrade using an ISO. They want to let Windows Update upgrade their Insider Dev build on an unsupported device to the next build, something I have been doing now for months. With a new Dev build released about once a week that has become something of a routine for me now.

I have already told you how I do that here in post #6, but I'll repeat it here and expand on it a bit.

Let Windows Update start the download and install. At about 8% downloaded Windows Update will run the compatibility checks, which of course will fail.

After it has failed, you can replace C:\$windows.~BT\sources\appraiserres.dll with a zero byte sized file with the same name. You can make one by making a New Text Document on your desktop and renaming it.



Copy this file to C:\$windows.~BT\sources\ to replace the existing one, you will be asked to use your administrator rights to do so. Then click Retry in Windows Update, this time it will skip all the checks and the download and install will run to completion.
