I've a problem within update

Question

Within an update, my laptop ask me an bitlocker number. But haven't this code, and i've not activate the device encryption.

In my Microsoft account, in device section, manage keys, your site tell me that it cannot find key?

How can I recover the operation of my computer ?

Answer 1

Step 1: Verify Your Microsoft Account

Go directly to https://aka.ms/myrecoverykey (Microsoft's official recovery portal)

Sign in with the exact same account used on your laptop

Try both personal and work/school accounts if you have multiple

Step 2: Check for Auto-Enabled Encryption

Even if you never activated BitLocker manually, Windows 11 automatically enables device encryption on most modern laptops (especially those with TPM 2.0). This explains why you're suddenly seeing this prompt after an update.

If Recovery Fails:

I'm afraid this means your data is no longer accessible. Your only option is a clean reinstallation:

Use another PC to create a bootable USB via Microsoft's Media Creation Tool

Boot from the USB and reinstall Windows

Note: This will erase all existing data on the laptop

Prevent This in the Future:

Once reinstalled, go to Settings → Privacy & Security → Device encryption and either:

• Disable it if you don't want encryption, or
• Back up your recovery key to a USB drive or print it for safekeeping
