Fixed a bug with C drive with yellow exclamation on Windows 10

Yellow exclamation is the most hated exclamation point for computer users. When the network symbol is exhausted, it means that you cannot connect to the network, when the drive is subject to regular gold exclamation, it will be formatted and lost.

The yellow exclamation mark on Windows drives often appears when the drive capacity is low, but if you are installing Windows 10, the possible cause is that Bitlocker drive encryption is turned off. Some users said they had this error after updating Windows 10 several times without success.

1. How are BitLocker and EFS different?

If your drives C, D, E have yellow exclamation points as shown below, try checking to see if Bitlocker is turned off and follow the instructions in this article to turn on Bitlocker.

Enter PowerShell in the search box.

Right-click PowerShell in the search results and select Run As Administrator .

The PowerPoint window will appear.

You enter the Get-BitLockerVolume command

The list of Bitlocker drives will be displayed. Notice that Protection Status is Off . Now we just need to turn it on.

Enter the Resume-BitLocker -MountPoint command 'C:' (or if the drive is yellowed not C, you replace C with the drive letter listed in the list above).

You will see Protection Status is now On. Open My Computer and see if the yellow exclamation mark on the drive disappears.
