All the important components and features for the good functioning of your Windows Operating System (for instance Windows 10) are made available to the end user through system services. Those services are making your system running smoothly with a lot of features making it very efficient in various situation.
*What is a bloatware
A software bloat (or bloatware) is a process making a system slower, use more memory, disk space or processing power, or have higher hardware requirements than its vanilla version, while making only minor user-perceptible improvements or even suffering from failures.
The term is often used to describe undesired features or changes, even if they have little or no effect on the system. Most end users will feel they only need some limited subset of the available functions in an operating system, and will consider others as unnecessary bloat (it is probably the case), even if different users with different configurations require those functions. .
*Why disabling unnecessary services and bloatware
You can disable unnecessary service in Windows 10 to improve your computer performance, security and system minimization. Moreover, some services may gives unexpected behaviors not explicitly requested by their system usage.
By default, the Microsoft Windows operating system embeds many components and functionalities which are not necessary for the good functioning of the system.
[II] Managing Windows 10 services
There are multiple ways to list Windows Services. An obvious one is by using the built-in GUI 'services.msc' into the Windows task bar. However, its is not very practical regarding system administration.
An other way (preferred by us) is by using the command-line prompt and the powershell toolkit...
Open a Windows Elevated BATCH command-line prompt (cmd as admin).
Typing the following command will gives you a list of all Windows Services including their status (Stopped or Running).
powershell -c Get-Service
Note the 2 distinct columns "Name" and "DisplayName". The "Display Name" is the usual name of the service that you may find reading the 'services.msc' GUI while the "Name" is the real "system" name of the related service.
The services listed in this article are named according to their "Name" (and not their "DisplayName").
With the following command, you will be able to list the "running" services
There are multiple ways to disable a service. However, disabling a bloatware may sometime become a touchy task due to permission issues, and this is why we also provide an « hard way » to force the disabling of a service.
The following table list some identified windows service, their description, and our recommendation to remove/disable them or not for removing bloatware while keeping the good functonning of the system.
Use the WinCleanSeckTo Script to automatically clean your system (based on this list).
Last Update: 18/03/2023. The list will be periodicaly updated. Keep watching it.

The Broadcast DVR server process is associated with Windows 10’s Game DVR feature. If you use Game DVR to record your PC gameplay or broadcast it online, the bcastdvr.exe process does the work. If you don’t use Game DVR for recording, this process sits silently in the background and does nothing.
The Base Filtering Engine (BFE) is a service that manages firewall and Internet Protocol security (IPsec) policies and implements user mode filtering. Stopping or disabling the BFE service will significantly reduce the security of the system. It will also result in unpredictable behavior in IPsec management and firewall applications.
Windows infrastructure service that controls which background tasks can run on the system.
AVCTP service is a Win32 service. In Windows 10 it is starting only if the user, an application or another service starts it. When the AVCTP service is started, it is running as NT AUTHORITY\LocalService in a shared process of svchost.exe along with other services. If AVCTP service fails to start, the failure details are being recorded into Event Log. Then Windows 10 will start up and notify the user that the BthAvctpSvc service has failed to start due to the error. Remove it if you don’t use Bluetooth Audio Device or Wireless Headphones

Some users that disabled the service went on to use their computers without any issues or side effects. However, some users have reported that they encountered some problems while connecting certain devices with the computer. Therefore, it is our recommendation that if you don’t use Xbox Live or any other Bluetooth devices with the computer regularly, you should disable the service.
if you don’t use Xbox Live or any other Bluetooth devices with the computer regularly, you should disable the service.
