File Path in UserForm connected to macros

Actually this works, but this opens and closes the workbook, not the best. :/

Any idea how to let it be closed?

Sub WriteValue()

    Dim MyPath          As String
    Dim MyFile          As String
    Dim Wkb             As Workbook
    Dim Cnt             As Long
    
    Application.ScreenUpdating = False
    
    MyPath = "C:\Users\molnar_a\Desktop\LW110\Support\" 'change the path accordingly
    
    If Right(MyPath, 1) <> "\" Then MyPath = MyPath & "\"
    
    MyFile = Dir(MyPath & "*.xlsx")
    
    Cnt = 0
    Do While Len(MyFile) > 0
        Cnt = Cnt + 1
        Set Wkb = Workbooks.Open(MyPath & MyFile)
        Wkb.Worksheets("Path").Range("B2").value = "Szöveg" 'change the new value accordingly
        Wkb.Close savechanges:=True
        MyFile = Dir
    Loop
    
    If Cnt > 0 Then
        MsgBox "Completed...", vbExclamation
    Else
        MsgBox "No files were found!", vbExclamation
    End If
    
    Application.ScreenUpdating = True
    
End Sub
