itunes 12.13.6 and apple devices app don't recognize my iphone on Windows 11

Hi! Thanks for your reply!

In fact I have already done most of these points in page "Troubleshooting issues with iTunes for Windows updates" (https://discussions.apple.com/docs/DOC-6562)

1) iTunes launch errors caused by QTMovieWin.dll => file not found => OK

2) Removing and reinstalling iTunes and other software components => I already went through these steps, I even saved and deleted extra entries from registry about ipod service, iTunes program....

3) iTunes launch errors caused by iAdCore.dll => file not found => OK

4) Install missing components => I went again now trough step 2 "Removing and reinstalling iTunes and other software components", I re-uninstalled everything.

Unipped iTunes64Setup.exe version 12.13.5.3

Reinstalled every msi components (Bonjour64.msi, AppleSoftwareUpdate.msi, AppleMobileDeviceSupport64.msi, iTunes64.msi), remark: Doing this way doesn't allow to execute msi files as Administrator ...

Did a shutdown of both my Computer and my iPhone 14 completely for at least 1 hour.

Connected my iPhone with lightning to USB cable, pressed yes to "Trust computer".

I can see, access and copy my picture files from Windows Explorer (This PC\Apple iPhone\Internal Storage).

Opened iTunes using "Execute as Administrator"

Got error "iTunes could not connect to this iPhone. An unknown error occurred (0xE8000003)"

Used Help > Run Diagnostics...

Selected 1) Network connectivity tests, 2) Device connectivity tests and 3) Device sync tests

Next >

1) Network connectivity tests => OK. Network interfaces verified OK, Internet connection veified OK and Secure link to iTunes verified OK => 3 green lignts Result: "All tests passed"

Next >

2) Device connectivity tests => KO. iPod support service not installed KO (red light). Apple Mobile Device is running OK. iTunes Helper is not running KO (red light). No USB ports found OK. No FireWire (IEEE 1394) ports found OK. No iPod, iPhone, or iPad found KO (red light)

Next >

3) Device sync tests => KO. No iPod, iPhone, or iPad found KO (red light)

Next >

After clicking last time on button "Next >" iTunes is freezing and can only be stopped using task manager > end task.

Restarted commputer

Opened iTunes normally, Help > Check for Updates

Downloaded and installed latest version 12.13.6.1 trough "Apple Software Update".

Restarted commputer one more time.

started iTunes.

Connected my iPhone with lightning to USB cable, pressed yes to "Trust computer".

Got again error "iTunes could not connect to this iPhone. An unknown error occurred (0xE8000003)".

Any other clue to resolve issue ?

Thanks for your next update....

Hello, i'm progressing a little bit on my way identifying root cause of iPhone not detected by iTunes on Windows11.

I'm getting error :

I can see in the Windows Event Viewer > Applications and Services Logs > Microsoft > Windows > CodeIntegrity > Operational:

Code Integrity determined that a process (\Device\HarddiskVolume3\Windows\System32\svchost.exe) attempted to load \Device\HarddiskVolume3\Program Files\Bonjour\mdnsNSP.dll that did not meet the Microsoft signing level requirements.

So my Question, when will Apple correct this issue and sign with correct required Microsoft signing authorizations file mdnsNSP.dll ???

I'm a bit surprised that not a lot of people are reporting this issue ...

Any clue about this issue and how to resolve it ?

Do I need to create a Windows 10 virtual machine on my Windows 11 computer to make iTune work again ?

I have just tried my son's computer with is Windows 10 and my iPhone is well recognized ...

I have been unable to make iTunes work under windows 11.... and THIS MAKES ME CRAZY after 5 weeks working on the issue ...

So my last idea and guess is to make it work using Windows10 virtual machine ...
