If your Windows 11 PC has started feeling slower than usual, you may not need to install a PC optimizer or start changing advanced system settings just yet.
Microsoft has highlighted a simple step that is easy to overlook: checking which apps are allowed to launch when Windows starts.
Over time, it is common for applications to add themselves to the startup list. The more programs that launch automatically, the more system resources can be consumed in the background—potentially making startup and everyday use feel sluggish.
Check your Windows 11 startup apps
Windows 11 makes it relatively easy to see which applications are configured to start automatically.
Open Settings > Apps > Startup.
You’ll see a list of apps along with their startup status. If you spot programs that you rarely need immediately after signing into Windows, you can turn them off.
Another option is to open Task Manager and select Startup apps. Windows shows the startup impact of applications, making it easier to identify programs that could be contributing to longer boot times. Microsoft also recommends using Task Manager to disable unnecessary startup items when troubleshooting Windows startup problems.
Don’t disable everything
There is an important catch: don’t simply turn off every startup application.
Some programs may need to launch with Windows for features such as synchronization, security or hardware utilities to work correctly.
Instead, focus on applications you recognize and don’t need running immediately after you sign in.
For example, a messaging app, game launcher or software updater that you rarely use may not need to start every time you boot your PC.
Why startup apps can make a difference
Startup programs can consume RAM, CPU resources and disk activity while Windows is loading and immediately afterward.
That doesn’t mean disabling a few startup apps will magically turn an old PC into a new one. However, on systems with lots of applications configured to launch automatically, cleaning up the startup list can make Windows feel more responsive.
It can also reduce the number of programs quietly running in the background.
Your storage could also be the problem
If disabling unnecessary startup apps doesn’t help, Microsoft recommends checking your available storage as well.
A Windows PC with very little free disk space can experience slower performance, and Microsoft recommends using Storage Sense and other built-in cleanup tools to remove unnecessary files.
You can check this under:
Settings > System > Storage
Windows 11’s Cleanup recommendations can also help identify temporary files and other data that can be safely removed. Storage Sense can automate some of this cleanup.
A few minutes of maintenance can go a long way
The useful thing about Microsoft’s advice is that it doesn’t require downloading another “PC booster” application.
Before reaching for third-party optimization software, try the basic Windows tools already available:
- Review unnecessary startup apps
- Check how much free storage remains
- Use Storage Sense to remove unnecessary files
- Check Task Manager for unusually high CPU or memory usage
- Keep Windows and your drivers updated
- Restart the PC if it has been running for an unusually long time
Microsoft’s own Windows performance guidance recommends several of these steps as part of troubleshooting a sluggish PC.
Is your Windows 11 PC slow?
A slow PC doesn’t always mean that the hardware is reaching the end of its life. Sometimes the culprit is simply a growing collection of applications running in the background.
So, before considering a hardware upgrade or reinstalling Windows 11, take a couple of minutes to check your startup apps. It’s a small setting that is easy to forget—and it could make a noticeable difference on some PCs.
