If you don't like the new Sticky Note that you got when you upgraded from Windows 10 version 1511 to Windows 10 version 1607 then here is a way to get the old Sticky Note back.
If you don't have win rar you download it and install it or you can download the zip version of StickyNotes.
1. Download StickyNotes.rar file and extract it. (For 64bit OS, use StickyFiles64 and for 32bit OS use StickyFiles86).
2. Create a folder "Sticky Notes" in Program Files. Copy StikyNot.exe and slc.dll files in it and create a folder "en-US" and copy StikyNot.exe.mui file in it.
Folder Hierarchy should be:
Program Files\Sticky Notes\en-US -> StikyNot.exe.mui
Program Files\Sticky Notes\ -> StikyNot.exe and slc.dll
Files should look like this:
3. Copy SNTSearch.dll in System32 folder (C:\Windows\System32)
4. Copy SNTSearch.dll.mui in System32\en-US (C:\Windows\System32\en-US)
You can create a shortcut to Sticky Notes by right clicking on the desktop and select new then shortcut,
After creating shortcut if you right click on the shortcut you can pin it to either the start menu or the taskbar.
