วิธีเพิ่ม pinned taskbar พิมพ์

1. Open regedit

2. Browse to the following key

   HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Advanced

3. Add a new DWORD (32-bit) entry named JumpListItems_Maximum

4. Set the value of JumpListItems_Maximum to the number of items you want to see in your jumplists (e.g., 19 (if hex) or 25 (if decimal))

Alternatively, you can make the registry change by saving the following text into a file named jumpList.reg and then importing it into the registry using File > Import... within regedit:

Windows Registry Editor Version 5.00

[HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Advanced]
"JumpListItems_Maximum"=dword:00000017

Sometimes the change takes effect immediately, but if not, don't forget to restart/new login!
