I want to ignore the solutions that I have mentioned below and focus on the ultimate solution. I will show you how to download the Windows 11 compatible audio drivers from the official site, uninstall the existing audio drivers from the machine then reinstall them.

Step #1: Download Audio Drivers from the Official Site

Your laptop drivers are available on the manufacturer’s site. Pre-build desktops have the drivers on the seller page or manufacturer page. I have an assembled Windows gaming machine and you can download the latest drivers from the motherboard manufacturer site. Let me show you the way and save Windows-compatible drivers.

  • Open the browser and search for the motherboard page.
  • Type the motherboard/laptop model number/pre-build desktop model number and open the official site page.

Step #4: Reinstall Audio Drivers

Almost all drivers are bundled in a ZIP archive and extracted the files in the local storage. Make sure to switch to an administrator account because Windows requires admin access to install drivers in the system.

4. Run Full System Scan

You should subscribe to a premium security solution and if you have one installed, then that’s a bonus point for you. Many users ignore the full system scan because it takes longer than an hour to finish the scanning process. However, I recommend you do it because the malware might be destroying the system files as we speak.

I will show you a method to scan the entire machine using Microsoft’s Security program. Disable Wi-Fi or remove the LAN cable before beginning the process.

  • Search for “Windows Security” and open the program.

1 - Open Windows Security

  • Choose the “Virus & threat protection” option.

2 - Select Virus & Threat Protection

  • Click on the “Scan Options” button.

3 - Choose Scan Options

  • Select the last fourth “Microsoft Defender Offline scan” option.

4 - Offline Scan Windows Machine

  • Click on the “Scan now” button.

Windows Security shuts down the computer and runs the scan in offline mode. The security scanning process takes less than fifteen minutes on modern computers with NVMe SSD. You can expect the security scan to be higher if the machine has older components.

5. Update Windows Software

Windows Update

Newer software always has drawbacks and the in-house developers take time to release patches. You should miss quality and security updates specially designed for Windows 11.

I recommend the users reinstall Windows 11 operating system from the bootable USB drive. You can watch any YouTube tutorial to install fresh Windows from a bootable USB drive and I have done it hundreds of times.

Bottom Line

You can solve “Can Not Connect RPC Service” by restarting the PC or reinstalling the drivers from the system. However, it’s not easy to fight against malware that is hiding in the storage drive, so you should consider reinstalling the OS to resolve the issue.
