+## 1. Issue: Model Loading Stuck Due To Missing Windows Management Instrumentation Command-line (WMIC)
+
+Encountering a stuck-on-loading model issue in Jan is caused by errors related to the `Windows Management Instrumentation Command-line (WMIC)` path not being included in the system's PATH environment variable.
+
+Error message:
+```
+index.js:47 Uncaught (in promise) Error: Error invoking remote method 'invokeExtensionFunc': Error: Command failed: WMIC CPU Get NumberOfCores
+```
+
+It can be resolved through the following steps:
+
+1. **Open System Properties:**
+   - Press `Windows key + R`.
+   - Type `sysdm.cpl` and press `Enter`.
+
+2. **Access Environment Variables:**
+   - Go to the "Advanced" tab.
+   - Click the "Environment Variables" button.
+
+3. **Edit System PATH:**
+   - Under "System Variables" find and select `Path`.
+   - Click "Edit."
+
+4. **Add WMIC Path:**
+   - Click "New" and enter `C:\Windows\System32\Wbem`.
+
+5. **Save Changes:**
+   - Click "OK" to close and save your changes.
+
+6. **Verify Installation:**
+   - Restart any command prompts or terminals.
+   - Run `where wmic` to verify. Expected output: `C:\Windows\System32\wbem\WMIC.exe`.
+
+
+## 2. Issue: Model Loading Stuck Due To CPU Without AVX
+
+Encountering an issue with models stuck on loading in Jan can be due to the use of older generation CPUs that do not support Advanced Vector Extensions (AVX).
+
+To check if your CPU supports AVX, visit the following link: [CPUs with AVX](https://en.wikipedia.org/wiki/Advanced_Vector_Extensions#CPUs_with_AVX)
+
+:::warning [Please use this with caution]
+As a workaround, consider using an [emulator](https://www.intel.com/content/www/us/en/developer/articles/tool/software-development-emulator.html) to simulate AVX support.

+
+When you encounter the error of old threads suddenly disappear. This can happen when a new, unintentional file is created in `/jan/threads`.
+
+It can be resolved through the following steps:
+
+1. Go to `/jan/threads`.
+
+2. The `/jan/threads` directory contains many folders named with the prefix `jan_` followed by an ID (e.g., `jan_123`). Look for any file not conforming to this naming pattern and remove it.
