tubaba, you check that winlogon.exe is running from system with LookupAccountSid, but I think it will not work with non-english OS. You can use IsWellKnownSid instead of LookupAccountSid. On autohotkey it will be like that: if DllCall("advapi32\IsWellKnownSid", "ptr", pSid, "uint", WinLocalSystemSid := 22) msgbox SystemSid

Your dll uses SetThreadToken function to set token. The same done via my link. Also you can use not-documented NtImpersonateThread instead of SetThreadToken.

For such a task you dont need dll.

Thanks for information! I will try.

1) Yes, It is good that You check that process runs from system account, but if there are several users on PC, then there are will be several winlogon.exe from system account with different TokenSessionIds. Will it be ok, that We will use token from different SessionId? 2) I tested on autohotkey. When You install it has an option run with ui access. If I run next script with ahk ui access and uac disabled then I will get TokenUIAccess = 0, but band = 2. Therefore I said that this function does not work. Code on ahk: DllCall("advapi32.dll\OpenProcessToken", "ptr", DllCall("GetCurrentProcess", "ptr"), "uint", 0x0008, "ptr*", hTokenSelf) ; TOKEN_QUERY DllCall("advapi32\GetTokenInformation", "ptr", hTokenSelf, "uint", 26, "uint*", TokenUIAccess, "uint", 4, "uint*", ReturnLength) msgbox % TokenUIAccess Gui, +HWNDhGui +AlwaysOnTop DllCall("GetWindowBand", "ptr", hGui, "uint*", band) msgbox % band Could You please give example how to create process with system and trustedinstaller permissions? Also I do not understand why do We need to call LookupPrivilegeValue, PrivilegeCheck and RevertToSelf functions.

Hi! I have some questions. 1) The author from github compares TokenSessionId of our process with TokenSessionId of winlogon.exe, but You dont. Is it not necessary? 2) The author from github creates process like this: GetStartupInfo(&si); if (CreateProcessAsUser(hTokenUIAccess, NULL, GetCommandLine(), NULL, NULL, FALSE, 0, NULL, NULL, &si, &pi)) You add "-s" to command line, add flags BitOR($NORMAL_PRIORITY_CLASS, $CREATE_NEW_CONSOLE) and add @SW_SHOW to $tStartupInfo structure. Why? 3) If You disabled uac then Func __CheckForUIAccess() will not work. But You can check TokenUIAccess with creating gui and calling GetWindowBand. On autohotkey like this: Gui, +HWNDhGui +AlwaysOnTop DllCall("GetWindowBand", "uptr", hGui, "uint*", band) Gui, Destroy hGui := "" if (band = 1) ; ZBID_DESKTOP

Just found a bug. Before calling JsDisposeRuntime We need to set set current context to not existent one with JsSetCurrentContext function.

Hi, smbape! Very interesting to test it. Thank You very much! Will You plan to add audio classifier example in future?

Hi, smbape! Will You plan to add object detection? https://developers.google.com/mediapipe/solutions/vision/object_detector/python Also here is new features like audio classifier, gesture recognizer, text classification... https://github.com/googlesamples/mediapipe/tree/main/examples

Great. Very good library for face recognitio!! Thank You! What the next? May be DeepFace? https://github.com/serengil/deepface

Thank You for explanation. Can We activate manifest only 1 time at start with DllActivateManifest, and deactivate it only before exit script with DllDeactivateActCtx? Can be some memory leaks? Also if We exit script without calling DllDeactivateActCtx, will be some memory leaks?

smbape, I think You have bug here: $sManifest = EnvGet("OPENCV_ACTCTX_MANIFEST") https://github.com/smbape/node-autoit-opencv-com/blob/main/autoit-opencv-com/udf/opencv_udf.au3#L123 Why user will have this environment variable? May be it is easier just use direct path to manifest?

Hi smbape! Sorry, but I dont know any other resources. Only some video tutorials like this: Thank You very much for such great work!

If You are interested here is dll https://github.com/HW140701/GoogleMediapipePackageDll

300ms - it is just an example. You can test like this. Exit all uia inspectors, exit skype, run skype, run AccExplorer32. https://github.com/blackrosezy/gui-inspect-tool/blob/master/AccExplorer32.exe Choose skype window, build tree with this utility -> as result You will see that Your tree will not have all child elements.
