Fix error 0X00000A3F RplConfigInfoCorrupted on Windows

Before you start

This error usually appears on older Windows machines (Windows 7, 8, 10) when you try to boot from a network. The error code 0X00000A3F means the Remote Program Load (RPL) config record is corrupted. This can happen after a bad Windows update, a power outage during boot, or if someone messed with the network settings manually.

The good news: you can fix this without reinstalling Windows. Follow the steps in order. Stop when the error is gone.

Fix 1: Quick check (30 seconds)

This is the simplest thing. No tools needed.

1. Restart your computer. Wait for it to fully boot into Windows.
2. Press the Windows key and type Command Prompt.
3. Right-click Command Prompt and select Run as administrator.
4. In the black window, type this and press Enter:

   sfc /scannow

5. Wait for the scan to finish. It checks system files. If it finds errors, it fixes them automatically.
6. Restart again. See if the error is gone.

What to expect: The scan takes 5-10 minutes. After restart, if the error doesn't show, you're done. If it still appears, move to Fix 2.

Fix 2: Reset the Remote Boot configuration (5 minutes)

This fix clears the corrupted RPL config using the registry. It's safe, but we'll back it up first.

1. Press Windows + R, type regedit, and press Enter.
2. In the Registry Editor, click File > Export. Save the backup somewhere (like your desktop) with a name like backup-before-fix.
3. Now go to this path in the left panel:

   HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\RemoteBoot

4. If you don't see RemoteBoot, skip to Fix 3. If you see it, click it.
5. In the right panel, look for a value named ConfigRecord. Right-click it and select Delete.
6. Close Registry Editor.
7. Restart your computer.

What to expect: After restart, Windows recreates the config record automatically. The error should be gone. If not, move to Fix 3.

Fix 3: Disable the Remote Boot service (15+ minutes)

If the first two fixes didn't work, the Remote Boot service itself is broken. Disabling it is the cleanest fix.

1. Press Windows + R, type services.msc, and press Enter.
2. Scroll down to Remote Access Connection Manager. Don't confuse it with something else.
3. Right-click it and select Properties.
4. In the Startup type dropdown, select Disabled.
5. Click Stop if the service is running (you'll see a button).
6. Click Apply, then OK.

Now disable the Remote Boot driver too:

1. Press Windows + R, type devmgmt.msc, and press Enter.
2. Click View > Show hidden devices.
3. Expand Non-Plug and Play Drivers.
4. Find RemoteBoot.
5. Right-click it, select Properties.
6. Go to the Driver tab, click Stop, then set Startup type to Disabled.
7. Click OK.
8. Restart your computer.

What to expect: After restart, the Remote Boot service won't load. The error 0X00000A3F shouldn't appear anymore. If you later need Remote Boot (unlikely for most people), you can re-enable it using the same steps but choosing Automatic.

What if none of these work?

If the error still shows up after all three fixes, try a System Restore to a point before the error started. Here's how:

1. Press Windows + R, type rstrui, press Enter.
2. Select Choose a different restore point, then click Next.
3. Pick a date when your PC worked fine.
4. Follow the prompts. Your PC restarts.

That's it. Most people fix this with Fix 1 or Fix 2. No need to reinstall Windows.
