Hey everyone! I'm having a frustrating issue trying to upgrade my system to Windows 11. Each time I try, the installation fails around the 30% mark and I get hit with error code 0xc1900204. I don't have any antivirus running in the background, so I'm stumped. Does anyone have a clue about what might be causing this and how I can fix it? Thanks for any help!

Error code 0xc1900204 usually means there's a problem with the update process itself or some faulty configurations. Since you've already turned off your antivirus, there are a few other things you can try. First, you might want to clear your Windows Update cache. Just run 'services.msc', stop the Windows Update service, and delete everything in the 'C:WindowsSoftwareDistribution' folder. After that, restart the service and give the update another shot. You should also run the SFC and DISM tools. They can help fix any corrupted files that might be causing the issue. If that doesn't work, check your program installation directory in the registry to make sure it's set to the correct path, which should be 'C:Program Files'. Lastly, using the Windows 11 Installation Assistant directly from the Microsoft website can be a great way to bypass this issue entirely.
Just to add on, I had a similar experience and changing the installation directory fixed it for me. Make sure the values for 'ProgramFilesDir' in your registry are correct. If it's pointing somewhere else, that might be causing the update to fail. Good luck!
