Find out What fontdrvhost.exe is and Why it's Running on your Windows.

i. The "fontdrvhost.exe" process is a legitimate Windows component that manages font rendering and font driver-related tasks. However, if it is consuming an excessive amount of RAM, it could be indicative of a problem or an issue with the font rendering system.

Here are some steps you can take to address the high RAM usage of fontdrvhost.exe:

1. **Restart Your Computer:**
Sometimes, simply restarting your computer can resolve temporary issues and free up system resources.

2. **Check for Windows Updates:**
Ensure that your Windows operating system is up-to-date. Microsoft regularly releases updates, including fixes for various system components. Go to Settings - Update & Security - Windows Update to check for updates.

3. **Update Graphics Drivers:**
Ensure that your graphics drivers are up-to-date. Outdated or corrupted graphics drivers can sometimes cause issues with font rendering and lead to high RAM usage. You can usually update your graphics drivers through the device manager or by visiting the website of your graphics card manufacturer.

4. **Scan for Malware:**
Run a full antivirus or anti-malware scan on your system. Malware can disguise itself as legitimate processes and cause abnormal resource usage. Use a reputable antivirus program to scan and remove any potential threats.

5. **Check for Font Issues:**
Issues with specific fonts could cause problems for fontdrvhost.exe. Try disabling or uninstalling recently added fonts to see if it makes a difference.

6. **Use the Windows Font Troubleshooter:**
Windows has a built-in Font Troubleshooter that can help identify and fix common font-related issues. You can find it in the Control Panel under "Troubleshooting" - "View all" - "Font Settings."

7. **Disable Unnecessary Services:**
Some third-party applications or services might interfere with font rendering. Temporarily disable non-essential services and startup programs to see if the issue persists.

8. **Perform a System File Check (SFC):**
Open a Command Prompt as an administrator and run the command `sfc /scannow` to check for and repair corrupted system files.

If the issue persists after trying these steps, it may be helpful to monitor the fontdrvhost.exe process using the Task Manager to see if there are specific patterns or triggers causing the high RAM usage. Additionally, you might consider seeking assistance from Microsoft support or community forums for more specialized help.
