Cache Clearing on Xiaomi RedmiBook 9 Pro: A Complete User Guide

Over time, any laptop starts to work slower — programs open longer, the system “hangs”, and free space on the disk mysteriously disappears. The culprit of these problems is often hidden in the cache: temporary files that create the operating system, browsers and applications. Xiaomi RedmiBook 9 Pro is no exception: even with its powerful “iron” (Intel Core i5-10210U or i7-10510U, up to 16 GB of RAM), the accumulated cache can slow down.

Cache cleaning is a simple procedure that requires no technical skills, but has nuances. For example, removing the system cache through Disk Cleanup is safe, but cleaning the AppData\Local\Temp folder manually can delete important temporary files of active programs. In this article, we will discuss how to properly clean the cache on RedmiBook 9 Pro without risking data, what tools to use, and what to do if problems remain after cleaning.

Xiaomi RedmiBook 9 Pro features Windows 10/11 preinstalled with Xiaomi-branded utilities (such as Mi Bluetooth or Xiaomi PC Suite) that also create cache that standard Windows tools don’t always remove, so below you’ll find ways to both clean and “deep” – with Xiaomi devices in mind.

1.What is cache and why should it be cleaned on RedmiBook 9 Pro

Cache is a temporary file that is created to speed up programs. For example, browsers save copies of images and scripts of sites so that when you visit the page again, the operating system caches frequently used data, and games - textures and levels. On RedmiBook 9 Pro, the cache can take from 500 MB to 10+ GB, depending on the intensity of use.

However, over time, the cache turns from assistant to enemy:

📉 Slows down the system: fragmented temporary files cause the hard drive (SSD or HDD) work harder, which slows down the laptop.
🗑️ Occupying space: on the system drive C: can accumulate up to 20 GB of unnecessary files.
🔄 Causes errors: corrupted application cache (e.g, NVIDIA GeForce Experience or Microsoft Store causes crashes.
🔒 Security threat: browser cache can store authorization data, history of visits and even passwords.

On RedmiBook 9 Pro, cache accumulates faster due to:

Xiaomi proprietary software (such as Mi Share or Xiaomi Cloud) that runs in the background.
Pre-installed games (such as League of Legends or PUBG Lite in some regional versions) that actively cache data.
Features of drivers for NVIDIA MX350 (in versions with discrete graphics), which create large temporary files.

⚠️ Note: Do not confuse cache with hiberfil.sys and pagefile.sys files, which can be deleted without preparation, and can lead to inability to exit from sleep mode or performance decline.
