Solving the problem that Windows To Go U disk does not have a drive letter

A lot of people have tried Windows To Go and found that no matter how the U disk is formatted, the U disk cannot be automatically assigned a drive letter after being inserted into the computer.
This is because when you create a Windows To Go USB drive with a wizard, Windows sets the disk with the NODEFAULTDRIVELETTER flag. Therefore, when the disk drive is inserted at any time in the future, Windows does not assign a drive letter to the disk. This mechanism should be easy to understand, because, as a Windows To Go drive, it is equivalent to a C partition on a normal PC, which mainly stores the system, and people generally do not access the partition frequently through the resource manager (if your Most of the data is placed in other partitions). For a drive, the purpose of assigning a drive letter is to facilitate daily access. For such infrequently accessed drives, even if someone else plugs your Windows To Go U disk into their computer, it is reasonable to not assign a drive letter to it, and this is taken into account when designing. Formatting does not clear the flags in some of the properties of the disk, so a formatted Windows To Go USB drive cannot be automatically assigned a drive letter. How to solve this? We have to use the Windows built-in Diskpart command line tool to reset the disk: 1. Open the cmd command prompt window (run as administrator); 2. Execute diskpart, and list disk, find the number of your USB flash drive ( In this case, it is 1), then select the disk through select disk 1; 3. Execute the clean command to clear all data, format and initialization information of the disk (this step is to clear the NODEFAULTDRIVELETTER flag); 4. Next, you have to create a Disk partitioning is required to format Windows. For U disk, we default to a partition, so execute create partition primary. 5. To use the disk, you have to format it. However, if you are fed up with the command line, you can finally go directly to the resource manager to format it~ If you still like the command line, then we can continue to execute format fs=fat32 quick. Ok, execute exit twice. Just exit the diskpart tool and cmd. Now the U disk is back to normal, and the computer will get an automatically assigned drive letter.
