The official version is lightweight, but it still installs deep hooks into your Windows OS.
Yes, with caveats.
The Golden Rule: Always download portable tools from verified community sources. Do not grab random .exe files from banner ads promising "Baidu PC Faster Portable 2025 Extreme Edition." That is how you get ransomware.
This is Baidu PC Faster’s killer feature. Click the "Boost" button, and the software temporarily kills non-essential background processes. On a portable drive, this is incredible for gaming laptops at LAN parties—clean the RAM without installing persistence.
Portable tools that require deep system access have one major flaw: UAC & Process Killing.
Because the portable version doesn't "install" a driver or service, it sometimes fails to kill stubborn Windows processes (like svchost.exe). The installed version loads a kernel driver that gives it god-mode access. The portable version relies on standard user permissions.
Fix: When running the portable version, always right-click and select "Run as Administrator."
It is important to note: Baidu officially discontinued PC Faster several years ago.
