Why does a window pop up in windows?

Question

Windows

Hello.
Once a day at 12:35 on my computer, a small window pops up for about 5 - 10 seconds and hides.
I checked my computer with kaspersky and found nothing.
In the event log at this time, only this thing
Log name: Windows PowerShell
Source: PowerShell (PowerShell)
Details:
CommandInvocation(Add-Type): "Add-Type"
ParameterBinding(Add-Type): name="MemberDefinition"; value="[DllImport("user32.dll")] public static extern int SendMessage(int hWnd, int hMsg, int wParam, int lParam);[DllImport("user32.dll")] public static extern IntPtr GetWindow(IntPtr hWnd , uint uCmd);[DllImport("user32.dll", EntryPoint = "FindWindowEx")] public static extern IntPtr FindWindowEx(IntPtr hwndParent, IntPtr hwndChildAfter, string lpszClass, string lpszWindow);[DllImport("user32.dll", SetLastError =true)] public static extern bool SetWindowPos(IntPtr hWnd, IntPtr hWndInsertAfter, int X, int Y, int cx, int cy, uint uFlags);[DllImport("user32.dll")] public static extern bool ShowWindow(IntPtr hWnd , int nCmdShow);[DllImport("user32.dll")] public static extern int SetWindowLong(IntPtr hWnd,
ParameterBinding(Add-Type): name="Name"; value="NativeMethods"
ParameterBinding(Add-Type): name="Namespace"; value="Win32" Of
course, the window does not interfere, but I would like to know what it is
Thank you.
