Many of us use high-end digital equipment like laptops, tablets, and personal computers. To ensure the optimum functioning of these devices for a prolonged period, they need to be serviced and updated regularly. 

‘CULauncher.exe’ is one of the features that Windows 10 recently added to its updates. It is an executable file (.exe) meaning; it executes a series of codes and commands as soon as the system boots. This feature was integrated into the Windows operating system to provide a secure and authentic startup to the device.

Automatic updates are very beneficial. The computer ensures its optimization, and the user need not get into the hassle of sifting through programs that are to be updated. However, that very pro is also a con. The user is unaware of the programs and software that are added, removed, or upgraded in the system, and this could impact the device adversely and also negatively impact the user interface.

Why do users want to stop automatic updates, if generally, it is beneficial both for the user and the device?

There are several reasons why users prefer to stop automatic updates:

  1. They want more control over their device rather than handing it over to the operating system itself.
  2. Automatic updates run in the background of your primary functions on the device slowing down the system speed and processing as a whole.
  3. Removing software that is of a negative purpose to the device and user is reinstalled by Windows 10.
  4. Automatic updates often cause troubleshooting problems.
