Disable new addressbar & searchbox feature of Windows 10 1909:
Windows 10 1909 aka 19H2 features an addressbar & searchbox which is wider than any before. To restore the old searchbox & addressbar, from inside the 
'Disbale Enable 1909 New Search' folder, run the 'Disable New Search.cmd' file to disable & alternatively run the 'Enable New Search.cmd' file as administator to 
re-enable the new addressbar & searchbox.
Big thanks to Mr GRiM @ Virtual Customs for sharing these.

Extras:
Lockscreens @ 1920x1080 & 2560x1440 resolutions.

Bugfix:
Getting rid of white areas in themes after coming out of lock or sleep in Windows 10
Windows 10 loads theme color defaults from:
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Themes\DefaultColors] after every lock/sleep/hibernate.

Hence any time you put your pc to sleep/ hibernate or use Ctrl+Alt+Del to go to the lock screen & then resume back to windows,
certain areas of task manager & other windows turn white while using custom dark themes

Fix:
Open regedit & navigate to
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Themes\
Under themes you'll find a folder/registry key called: 'DefaultColors'
Make a backup of that key, take ownership of it, and then delete that whole key.
The bug should be fixed now.

Enjoy.
