Find out What Windows' WMI provider host is.

i. High CPU usage by the WMI Provider Host (`WmiPrvSE.exe`) is a common issue that users may encounter on Windows systems. This problem can lead to performance issues, slowdowns, and increased resource consumption. Here are several steps you can take to troubleshoot and address high CPU usage by the WMI Provider Host:

1. **Check for Malware:**
- Run a full system scan using your antivirus or anti-malware software to ensure that your system is not infected.

2. **Restart the WMI Service:**
- Open the "Run" dialog (Win + R), type `services.msc`, and press Enter.
- Locate "Windows Management Instrumentation" in the list.
- Right-click on it, select "Restart," and see if the CPU usage returns to normal.

3. **Repair WMI Repository:**
- Open the Command Prompt as an administrator.
- Run the following commands to stop the WMI service and perform a repository repair:
```bash
net stop winmgmt
winmgmt /resetrepository
net start winmgmt
```
- Reboot your computer and check if the CPU usage improves.

4. **Identify Problematic WMI Provider:**
- Use the WMI Diagnosis Utility (`WMIDiag`) to identify and fix issues with specific WMI providers.
- Download and run `WMIDiag` from the Microsoft website.

5. **Disable Specific WMI Providers:**
- Temporarily disable specific WMI providers to identify if a particular provider is causing the high CPU usage.
- Open the "Run" dialog (Win + R), type `wbemtest`, and press Enter.
- Click "Connect" and connect to the root namespace.
- Click "Enum Classes," enter `__Win32Provider` in the "Superclass Name" field, and click "OK."
- Locate and disable individual providers to observe the impact on CPU usage.

6. **Update or Rollback Drivers:**
- Outdated or incompatible device drivers can sometimes lead to WMI-related issues.
- Update your drivers, especially graphics and chipset drivers, to the latest versions.
- If the issue started after a driver update, consider rolling back to the previous version.

7. **Check for Windows Updates:**
- Ensure that your Windows operating system is up to date.
- Install the latest Windows updates, including security updates and patches.

8. **Consider Professional Help:**
- If the issue persists, consider seeking assistance from Microsoft support or IT professionals who specialize in Windows system troubleshooting.

ii. When you're experiencing high CPU usage from processes like the WMI Provider Host (`WmiPrvSE.exe`) and Spooler SubSystem App (`spoolsv.exe`), it can impact system performance. Here are steps to troubleshoot and address high CPU usage for each of these processes:

### WMI Provider Host (`WmiPrvSE.exe`):

1. **Restart the WMI Service:**
- Open the "Run" dialog (Win + R), type `services.msc`, and press Enter.
- Locate "Windows Management Instrumentation" in the list.
- Right-click on it, select "Restart," and observe if CPU usage improves.

2. **Repair WMI Repository:**
- Open the Command Prompt as an administrator.
- Run the following commands to stop the WMI service and perform a repository repair:
```bash
net stop winmgmt
winmgmt /resetrepository
net start winmgmt
```
- Reboot your computer and check if the CPU usage normalizes.

3. **Identify Problematic WMI Providers:**
- Use the WMI Diagnosis Utility (`WMIDiag`) to identify and fix issues with specific WMI providers.
- Download and run `WMIDiag` from the Microsoft website.

4. **Disable Specific WMI Providers:**
- Temporarily disable specific WMI providers to identify if a particular provider is causing high CPU usage.
- Open the "Run" dialog (Win + R), type `wbemtest`, and press Enter.
- Click "Connect" and connect to the root namespace.
- Click "Enum Classes," enter `__Win32Provider` in the "Superclass Name" field, and click "OK."
- Locate and disable individual providers to observe the impact on CPU usage.

### Spooler SubSystem App (`spoolsv.exe`):

1. **Clear Print Queue:**
- Open the "Run" dialog (Win + R), type `services.msc`, and press Enter.
- Locate "Print Spooler" in the list.
- Right-click on it, select "Stop," and then navigate to `C:\Windows\System32\spool\PRINTERS`.
- Delete all files in the PRINTERS folder.
- Restart the "Print Spooler" service.

2. **Update Printer Drivers.**

3. **Isolate Printer Issues:**
- Disconnect printers one by one and check if CPU usage returns to normal.
- Reconnect printers one at a time to identify if a specific printer is causing the issue.

4. **Monitor Print Jobs:**
- Open the "Printers & Scanners" settings on your computer.
- Check for any stuck or pending print jobs and cancel them.

5. **Clear Temp Files:**
- Open the "Run" dialog (Win + R) and type `%TEMP%`.
- Delete all files in the temporary folder.

6. **Check for Windows Updates.*
