Oh good gosh! Listening to all these upgrade problems sends a chill unto my spine. The issue was because I am still maintaining an in-house old system, the newer ones aren't as friendly as intended.

Wanna hear something funny?
Most of the hospitals are actually still using XP because they never wanted to upgrade because the system they used is stable. Anything that requires online, they use their phones to download.

Hence this is kind of my office's own thought process as well. Don't mess with the current system as long as it is still working 😅
