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.
