Windows 11 known for many things. It’s still standard issue for most corporate computing systems, the OS most familiar to most users, and often the first choice for anyone building or buying a new PC. However, it has also developed a reputation for a proliferation of unnecessary features that abuse system resources.
I’m not disputing a lot of Windows and its features don’t do it if the right user has space on their desktop (or rather background), the problem is that it’s often enabled by default for them. everything. Most people never understand what they are doing on their computer, let alone deciding whether the memory, CPU time or data they are consuming is worth it. Here are a few things in Windows 11 background that the average user doesn’t think about at all.
Windows health and optimized experiences
It’s mostly only useful for laptops, so if you’re on a desktop, you don’t need it.
Windows Health and Optimized Experiences, which appears as WHESVC in Task Manager, is one of Microsoft’s new background services that debuted in 2025. It starts as a delayed startup service on every Windows 11 PC and its purpose is very narrow. It simply monitors CPU load, heat, power profile, battery, and screen brightness, thus recording a local performance trace when the system becomes sluggish.
There has been a lot of buzz in the tech community that this service was created as a way for Microsoft to “spy” on its users. later denied by Scott Hanselman in the statement. The Microsoft vice president added that this information is stored locally and the data is only sent to Microsoft based on the user’s consent.
Although not spyware, this service is better suited for laptops and mobile devices, and running it on a desktop will not benefit the average user. can be turned off by Services In Windows 11. After opening the application, you need to find “Windows Health and Optimized Experiences” in the list and set its startup type. Off.
Added user experience and telemetry
Turn it off for a little privacy
This is one of those services that hides in plain sight. I found this in the Processes tab of Task Manager, where it was listed as Service Host: UtcSvc, which doesn’t give much information about what it does. The service under this cryptic nomenclature is Connected User Experience and Telemetry, better known by its former name DiagTrack.
DiagTrack collects diagnostic and usage data, including application and feature usage, driver reliability, and performance metrics, and sends it to Microsoft in accordance with your diagnostic data settings. While the resource drain on a healthy desktop isn’t anything to panic about, it’s certainly the kind of service a privacy-conscious user might want to turn off. That said, on some laptops, it can contribute to increased background activity in some workloads and cause them to overheat as a result.
You can also turn this off by going to the page Services and look for “Enhanced User Experience” and “Telemetry” and then click Stopthen set the Run Type Off. However, if the option is grayed out, you can use the elevated command line and the key below.
sc stop DiagTrack
sc config DiagTrack start = disabled
SysMain
The activity of a bygone era, a bygone era
SysMain is one of the oldest background services in Windows and its origins can be traced back to the dark ages of Windows Vista. Back then, it was known as Superfetch and it worked by learning which apps you use most often, preloading them into unused RAM, and launching the app a little faster.
The problem with this service is that it was designed for an era when hard disk drives (HDDs) were the norm. On a modern computer with an NVMe or SATA SSD, this service is meaningless, but it still runs in the background and shows up as obscure disk or CPU activity. Disabling it through Services is as simple and easy as disabling other services on this list, and all you have to do is search. SysMain in the list.
Download Maps Manager
It stores offline maps that you have never opened
If this is the first time you’ve heard the term “MapsBroker” in this article, you’ve never used an offline map on your Windows computer. A desktop connected to the Internet throughout the day will certainly not be more than one search for directions using Google Maps.
This makes the operation of the service somewhat inconvenient. It updates and manages offline maps in the background, a feature that 99% of users with internet access will not benefit from. If you’ve never downloaded offline maps, it’s just a delayed start service that’s there. As a matter of fact, CIS standardsWindows, a set of enterprise security hardening guidelines used by IT teams, recommends disabling it to minimize the attack surface. You can do this by searching for “Downloaded Maps Manager” through the Services.
Windows 11 is required a lot cutting
Most of these background services are harmless, but that doesn’t mean they’re useful. Some of these are legacy features that don’t fit the needs of the times, while others are timeless in their ability to solve problems that most desktop users don’t have. Whether it’s to reclaim system resources, remove apps you never use, or reduce the bloat that’s become a staple of the Windows experience, it’s important to audit your device.
