How to prevent arbitrary changes to drive-letters and removal of desktop icons. Also why still updates to Windows 10?

To address the issues you're experiencing with missing desktop icons and unexpected changes to drive letters, here are some insights:

1. Missing Desktop Icons: The disappearance of the desktop icon for your external drive can occur when the drive is not properly recognized by Windows. This can happen if the drive is disconnected improperly or if there are issues with the drive itself. When you reconnect the drive, Windows may not assign it the same drive letter or may not recognize it at all, leading to the icon being removed from the desktop. If the drive is not in the Recycle Bin, it may simply be that Windows is not currently recognizing the drive.
2. Changing Drive Letters: Drive letters can change for several reasons, including:
   • Windows Updates: Sometimes, updates can affect how devices are recognized and assigned drive letters.
   • Device Management: If multiple devices are connected, Windows may automatically assign letters based on availability, which can lead to changes.
   • Group Policy Settings: If you are in a managed environment, group policies can affect drive mappings.

To prevent these issues from recurring:

• Ensure that you safely eject your external drives before disconnecting them.
• You can manually assign drive letters to your external drives using Disk Management, which can help maintain consistency. However, be cautious when changing drive letters for drives that contain applications or the operating system, as this can lead to problems with those applications.
• If you are using Group Policy Preferences, be aware that certain settings can clear manually mapped drives, which may contribute to the issues you're seeing.

As for updates to Windows 10, Microsoft continues to provide updates to ensure security, stability, and performance improvements. Keeping your system updated is important for maintaining security and compatibility with new software and hardware.

Hi Byff,

Windows doesn’t permanently keep shortcuts for removable drives. When the drive is disconnected, the system may remove the icon instead of leaving it with a question mark. This usually happens because:

Shortcut type: If it’s a direct link to the drive, Windows may delete it when the target is unavailable.

System refresh after restart: Windows cleans up invalid shortcuts during boot.

No recycle bin entry: Since the shortcut is considered invalid, it’s deleted outright, not moved to the recycle bin.

drive letters change

Windows assigns drive letters dynamically. If the original letter is taken by another device or the system reorders devices during boot, your external drives can get new letters. This often occurs when:

Multiple external drives or USB devices are connected.

Fast startup or power management resets the mount order.

Windows updates or driver changes trigger hardware re-enumeration.

to prevent this:

Assign permanent drive letters

Open Disk Management (Win + X → Disk Management).

Right-click your external drive → Change Drive Letter and Paths → Assign a letter that’s unlikely to conflict (e.g., X:, Y:).

This setting is saved and should persist across reboots.

Disable Fast Startup

Go to Control Panel → Power Options → Choose what the power buttons do → Change settings that are currently unavailable.

Uncheck Turn on fast startup. This reduces hardware reordering during boot.

Create a persistent shortcut

Instead of linking directly to the drive, create a folder shortcut or use a symbolic link that won’t disappear when the drive is disconnected.

I know this feels like something Windows should handle better, but the system prioritizes dynamic hardware management over static shortcuts. Setting permanent letters and using stable shortcuts will save you from having to fix paths repeatedly. Let me know how it goes, Happy to help!
