Yes, it can be safe to disable certain Windows services to improve performance, but it depends on which ones you're disabling. Some services are critical for system stability, security, or hardware functionality. Disabling the wrong ones might cause issues like network problems, missing features, or even system crashes.
If done carefully and with understanding, tweaking unnecessary services can free up memory and CPU usage — especially helpful on older machines or systems with limited resources.
Identify non-essential services before disabling
Before turning off any service, research what it does. You can check services via services.msc in the Run dialog (Win + R). Here’s how to approach this:
- Look for services related to features you don’t use, like Fax, Print Spooler (if you don't print), or Bluetooth Support.
- Avoid disabling anything labeled “Automatic” by default unless you’re sure — these often support core functions.
- Use tools like Black Viper’s Service Configurations or trusted tech websites to get safe configuration suggestions.
A few examples of commonly safe services to disable:
- Connected User Experiences and Telemetry
- Diagnostic Policy Service
- Downloaded Maps Manager
But again, only disable if you understand what they do and you’re not using those features.
Performance gains are usually minor
Disabling services won’t magically speed up your PC. Most background services consume minimal resources when idle. The real benefit comes from stopping resource-hungry ones that run frequently or keep your disk busy.
For example:
- Background services like Superfetch or Windows Search may help performance over time, so disabling them could actually slow things down initially.
- On low-end systems, turning off visual effects or telemetry services might offer a slight improvement in responsiveness.
So while there can be gains, especially on older hardware, it's not always dramatic — and it's easy to lose more than you gain if you're not selective.
How to disable a service safely
If you decide to proceed, follow these steps:
- Press Win + R, type
services.msc, and hit Enter. - Scroll through the list and double-click the service you're considering.
- Check the "Startup type" dropdown — if it's already set to Manual or Disabled, you probably don’t need to touch it.
- Change the Startup type to Disabled or Manual, depending on whether you want to block it completely or let it start only when needed.
- Click Apply, then OK.
?? Important: Don’t stop a running service unless you know what it affects. Stopping something mid-process could freeze apps or crash your session.
Also, consider creating a restore point before making major changes. That way, you can roll back quickly if something breaks.
Most people will find that a handful of services can be turned off without consequence, but it's not a one-size-fits-all fix. Know what you're disabling, and test your system afterward to make sure nothing important is broken.基本上就這些。

Is the performance of RTX5090 significantly improved?
Mar 05, 2024 pm 06:16 PM
Many users are curious about the next-generation brand new RTX5090 graphics card. They don’t know how much the performance of this graphics card has been improved compared to the previous generation. Judging from the current information, the overall performance of this graphics card is still very good. Is the performance improvement of RTX5090 obvious? Answer: It is still very obvious. 1. This graphics card has an acceleration frequency beyond the limit, up to 3GHz, and is also equipped with 192 streaming multiprocessors (SM), which may even generate up to 520W of power. 2. According to the latest news from RedGamingTech, NVIDIARTX5090 is expected to exceed the 3GHz clock frequency, which will undoubtedly play a greater role in performing difficult graphics operations and calculations, providing smoother and more realistic games.

Optimize PHP multi-threaded operations and improve database performance
Jun 30, 2023 am 10:27 AM
How to improve database read and write performance through PHP multi-threading. With the rapid development of the Internet, database read and write performance has become a key issue. When our application needs to frequently read and write to the database, using a single-threaded approach often leads to performance bottlenecks. The use of multi-threading can improve the efficiency of database reading and writing, thereby improving overall performance. As a commonly used server-side scripting language, PHP has flexible syntax and powerful database operation capabilities. This article will introduce how to use PHP multi-threading technology to improve

This article will introduce how to use PyPy to improve the performance of Python programs. 1. What is PyPy? PyPy is a just-in-time compiled Python interpreter
How is win11 better than win10?
Jan 04, 2024 am 08:28 AM
Presumably everyone's computer system has been updated to win11, so what are the advantages and disadvantages of win11 system compared to win10 system? This is what everyone wants to know. Let's take a look at the specific advantages and disadvantages together. What are the advantages of win11 over win10: 1. Smoothness. Win11 is better than win10 in terms of single-threaded and multi-threaded 3D operation. However, the response speed of win11 is relatively slow, and you need to wait for a while after clicking. 2. The performance of games is better than win10, and the average frame rate is also better than win10. However, the memory optimization is poor, the memory and CPU consumption are much higher than win10.3, and the operation interface uses too many rounded corners. Desktop ui mining
