How to get old Sticky Notes back after December 2018 update to Windows 10?

To run old Sticky Note in Windows 10 Version 1809 aka. October 2018 Update, StikyNot.exe needs a compatible DUI70.DLL file (Windows DirectUI Engine). A fair bit of warning, there are many websites which provide DLL files (Dynamic Link Library) for free. DO NOT download them because they may contain harmful malwares.

There are many ways to download old Windows 10 ISO files. Here I have choose a tool from HeiDoc.net which uses official Microsoft link to download ISO files. For this procedure, I have used two Windows 10 versions --

• Version 1511 (November Update) for StikyNot.exe and StikyNot.exe.mui
• Version 1803 (April 2018 Update) for DUI70.DLL and DUI70.dll.mui

Extract those files from their ISO files respectively. Here are the list of what we need:

Win10_1511_English_x64.iso
|
+-- sources
    |
    +-- install.wim
        |
        +-- Windows\System32\StikyNot.exe
        +-- Windows\System32\en-US\StikyNot.exe.mui

Win10_1803_English_x64.iso
|
+-- sources
    |
    +-- install.wim
        |
        +-- Windows\System32\DUI70.dll
        +-- Windows\System32\en-US\DUI70.dll.mui

The en-US folder may change according to the main locale of that ISO file, for example, en-GB for UK English, zh-CN for simplified Chinese etc. Copy those above four files in any folder like this:

MyFolder
|
+-- StikyNot.exe
+-- DUI70.dll
|
+-- en-US
    |
    +-- StikyNot.exe.mui
    +-- DUI70.dll.mui

Alternatively, both files can be copied from Windows 7 ISO file. So how did I find the dependency of DUI70.dll? Answer, with Dependencies tool (open-source and free) and some trial 'n error. Open the StikyNot.exe in that tool. It will show many functions are imported from DUI70.dll library. The other imported functions are from System32 libraries.
