Summary of "11 dịch vụ Windows vô dụng đang ngốn RAM của bạn ngay lúc này (Cân nhắc tắt ngay)"
Overview
This video explains how to disable certain “unnecessary” Windows background services to reduce RAM/CPU usage and improve responsiveness. It stresses that you should not blindly disable everything—only turn off a service if you’re sure you won’t use the related Windows feature. It also notes that changes are reversible.
Main tutorial workflow (how to change services)
Open the Services console
- Press Win + R
- Type:
services.msc - Press Enter
Navigate the service list
- Press letters like C / W / D / P / B / S to quickly jump to services starting with those letters.
Disable a service
- Double-click the service
- Set Startup Type to Disabled
- Click Stop
- Click Apply
- Click OK
Changes described in the video are reversible (you can set the service back to Automatic later).
Services highlighted (what they do + who should disable/keep)
1) Connected User Experiences and Telemetry
- What it does: Tracks usage/diagnostics and sends data to Microsoft in the background.
- Disable if: You want less privacy/telemetry.
- Impact: Minimal daily user-facing changes; less background activity/data sent.
2) Windows Error Reporting Service
- What it does: Collects diagnostic data when apps crash/freeze and sends it to Microsoft.
- Disable if: You don’t want to send crash/bug data.
- Impact: Shouldn’t break normal app functionality or destabilize Windows.
3) Diagnostic Policy Service
- What it does: Monitors for issues (network/performance/account) and attempts automated troubleshooting.
- Disable if: You troubleshoot yourself or don’t rely on built-in troubleshooting.
- Keep if: You frequently use Windows troubleshooting tools.
4) Program Compatibility Assistant Service
- What it does: Detects compatibility issues for older software (e.g., suggests Win7 compatibility mode/admin).
- Disable if: You only use modern, updated apps.
- Keep if: You frequently run older Windows 7/8-era applications and need compatibility detection.
5) Windows Biometric Service (Windows Hello)
- What it does: Enables biometric login (fingerprint/face).
- Keep if: You use fingerprint/infrared face login.
- Disable if: You only use password/PIN and never use biometrics.
6) Windows Search
- What it does: Builds a search index for fast Start menu/file searches.
- Resource cost: Roughly 50–200 MB RAM and can cause CPU spikes. On HDDs, continuous reads/writes may slow performance.
- Disable if:
- You manually search folders, or
- You use alternative tools like Everything (or similar launchers), or
- You have low-spec/older systems—especially with HDD storage.
- Keep if: You frequently use Start menu search.
- Note: Disabling doesn’t remove the search bar, but Windows may search more slowly in real time.
7) BitLocker Drive Encryption Service
- What it does: Background service related to BitLocker (pre-loaded).
- Keep if: You use BitLocker on any drive (disabling may cause encrypted-drive issues).
- Disable if: You never use BitLocker and no drives are encrypted.
8) SysMain (previously Superfetch)
- What it does: Learns frequently used apps and preloads them into RAM (predictive caching).
- Keep if: You have an HDD (can improve app launch speed due to slow disk reads).
- Disable if: You have SSD/NVMe (benefit is smaller; it still writes/preloads and can consume RAM/IO).
Optional services depending on usage
-
Bluetooth Support Service
- Disable if you use no Bluetooth devices
- Keep if you use Bluetooth peripherals
-
Remote Desktop Services / Remote Desktop Configuration
- Disable if you never remote into/control the PC
- Keep if you frequently use remote access
-
Print Spooler
- Disable if you don’t have/connect a printer (or don’t print)
- Re-enable if software misbehaves, since some apps may rely on it
Extra cleanup: remove leftover third‑party startup services (MSConfig)
The video suggests using System Configuration to disable third-party services left behind.
-
Open System Configuration:
- Win + R →
msconfig - (Subtitles mention “machine config”.)
- Win + R →
-
Go to the Services tab
- Check: “Hide all Microsoft services”
This filters the list to third-party services only.
- If you see services from apps you no longer use (possibly after uninstalling software, update managers, or old hardware utilities), uncheck them.
- A restart is recommended to apply changes.
Verification / analysis steps after changes
After restarting:
Check performance (idle)
- Open Task Manager → Performance
- Watch CPU/memory graphs while the system is idle
Check process memory usage
- Go to Task Manager → Processes
- Sort by memory to see whether fewer background processes are consuming RAM
The video claims that fewer background services can improve:
- Idle responsiveness
- Boot time
- Overall resource efficiency, especially on older or low-RAM machines
Safety / reversibility guidance
- There’s no universal service list—decide based on your use case.
- If disabling a service causes weird behavior:
- Re-enable it by setting Startup Type back to Automatic
- Start the service again
