Unofficial English patch for Xiaomi PC Manager

Unofficial. This project is not affiliated with, endorsed by or supported by Xiaomi. "Xiaomi" and "Mi" are trademarks of Xiaomi Inc. No Xiaomi software is distributed here: the tool modifies the copy of Xiaomi PC Manager that is already installed on your PC.

XpmTranslator.exe translates Xiaomi PC Manager 5.8.1.130 (Chinese only) into English and fixes a few bugs that show up on non-Chinese Windows. It patches the files of your own installation; nothing is downloaded and Xiaomi's servers/updates keep working.

Download

Get XpmTranslator.exe from Releases. It is built from this repository by GitHub Actions; the SHA-256 of every build is listed in the release notes.

Use

1. Run XpmTranslator.exe (it asks for administrator rights — it writes to C:\Program Files\MI\XiaomiPCManager).
2. Keep the components you want ticked and press Apply. PC Manager is closed and started again.
3. Restore originals puts every original file back. Unticking a component and pressing Apply restores just that one.

Originals are backed up to %ProgramData%\XpmTranslator\<version>\ before anything is replaced, together with a manifest of what was written. The tool only patches files whose SHA-256 matches the stock 5.8.1.130 files; if a file was changed earlier (e.g. by a manual translation attempt) it looks for the original in its backup, in <file>.bak* next to it, and in a backup\ folder next to the tool.

Command line (for scripts): XpmTranslator.exe status | apply [all|ids…] | restore | build <dir> [ids…], options --app <dir>, --originals <dir>, --store <dir>, --no-restart.

Before you use it

• Use at your own risk. Modifying PC Manager may be against its license terms.
• Patched .dll files lose Xiaomi's digital signature; some antivirus programs may complain about them or about the patcher itself.
• Updating PC Manager replaces the patched files — run the tool again. Files of other versions than 5.8.1.130 don't match the known hashes and are not patched; a new version needs its dictionaries checked first (see Source).

Components

id	What	Files
web	Main window: all 831 texts of the web UI, plus PC Cleanup group/item names (they come from the native cleaner at run time, Data\cleanup.json)	dist\static\js\main.js
pri	Control Center (tray), Mi File Transfer, pop-ups, update/exit dialogs, subtitles window — 540 strings	resources.pri
asm	Texts built into code: transfer notifications, earphone hint, subtitle defaults	PcControlCenter.dll, SubtitleTranscriptor.dll
osd	Fn-key on-screen pop-ups (captions are drawn into the images)	476 × res\Image\*.png
skin	"Non-original charger" warning window	skin\xml\LowPowerAlertWnd.xml, skin\image\NoLongerRemind*.png
privacy	Privacy policy shown on first start and the "withdraw consent" notice (unofficial translation, marked as such; the Chinese original remains the binding version)	Assets\privacy_content\privacy.txt, cancel_privacy.txt
layout	Layout fixes so English fits: cards, sidebar, header, drop-downs, buttons	dist\index.html, new dist\static\css\custom.css
mui	Crash fix. WinUI loads its own strings from <lang>\Microsoft.ui.xaml.dll.mui; only zh-CN is shipped, so on other Windows languages every WinUI dialog (e.g. "new version available") throws 0x80073B01 and the app closes. Copies the genuine en-US file from the Windows App Runtime 1.4 installed on your PC after checking its MUI checksums match.	new en-US\Microsoft.ui.xaml.dll.mui
otalog	"????" in the update window. Xiaomi's native code converts the release notes through the ANSI code page, so Chinese text arrives as ?. Such unreadable notes are replaced with "Bug fixes and improvements."; readable text is shown as is.	XiaomiPcManager.dll

Not covered: the AI File Search window (Search\), the clipboard window (PcClipboard\), a few strings inside the signed native OSDUtility.exe.

src — C# (.NET 10, WinForms, Mono.Cecil). Build:

dotnet publish src -c Release -o publish

• Patches\WebBundle.cs — finds every \uXXXX-escaped Chinese literal in the minified bundle by expanding to the enclosing quotes, skips logging calls / the weather city table / Lottie layer names, replaces whole literals from Data\web.json.
• Patches\PriFile.cs — rewrites [mrm_dataitem] sections of the PRI file (UTF-8/UTF-16 strings, also short strings stored as blobs) and recomputes the TOC; resource maps reference items by index.
• Patches\Assembly.cs — string literal replacement and the injected __SanitizeUnreadable filter.
• Patches\Mui.cs — MUI checksum check and framework lookup.
• Data\ — embedded dictionaries, CSS, pre-rendered images, originals.json (hashes of stock files).

tools — how the data was made:

• translations\ — source lists (js_todo.json + js_en.txt, pri_todo.json + pri_en.txt, assembly maps). In the *_en.txt files a trailing § means a trailing space.
• scripts\make_data.py regenerates Data\; extract_js.py/filter_js.py/pri_todo.py list strings of a new version; osd_render.py/skin_render.py redraw captions with MiSans/Segoe UI.
• harness\shot.js — renders the web UI in headless Edge with a stubbed WebView2 bridge and reports text that overflows its box (used to tune custom.css).

The scripts work on files taken from your own PC Manager installation; those files are not part of this repository and must not be committed.
