How do I get my old Post-it notes back after the December 2018 update to Windows 10?

To run old sticky notes again in Windows 10 version 1809. October 2018 update, StikyNot.exerequires a compatible DUI70.DLL file (Windows DirectUI engine). A little warning, there are many websites that provide DLL files (Dynamic Link Libraries) for free. Do not download them as they may contain harmful malware.

There are many ways to download old Windows 10 ISO files. Here I have selected a tool from HeiDoc.net which downloads the ISO file using the official Microsoft link. In the process, I used two Windows 10 versions -

• Version 1511 (monthly update) for StikyNot.exeandStikyNot.exe.mui
• Version 1803 (updated April 2018) for DUI70.DLLandDUI70.dll.mui

Extract these files from their ISO files, respectively. Here is 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

This en-USfolder may change depending on the main locale of the ISO file, eg, en-GBfor British English, zh-CNfor Simplified Chinese, etc. Copy the above four files into any of the above folders as follows:

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

Alternatively, both files can be copied from the Windows 7 ISO file. So how do I find the dependencies DUI70.dll? Answer, use the " dependencies" tool (open source and free) and some trial 'n errors. Open StikyNot.exein that tool . It will show that many functions are imported from the DUI70.dlllibrary . Other imported functions come from the System32 library.
