Stuck desktop when i create multiple desktop.

This behavior is consistent with known desktop and Explorer-related issues rather than expected virtual desktop behavior.

Two relevant causes are documented:

1. Virtual desktop interaction issues have existed in Windows desktop implementations On Windows 8.1 and Windows Server 2012 R2, Microsoft documented a problem where mouse actions could be blocked when creating a new virtual desktop. The cause was that mouse hooks were invoked across desktops, and the fix was included in security update 3002885.
2. Explorer desktop rendering issues can occur when desktop resources are stressed or corrupted Microsoft also documents cases where the desktop is not shown correctly and Explorer resource usage increases significantly. In addition, File Explorer and desktop icon problems can be caused by corrupted icon cache or shell component issues.

For a practical fix path on a Windows client:

1. Restart Windows Explorer Since restarting Explorer already restores the desktop, that strongly points to an Explorer or shell-state issue.
2. Clear the icon cache This is a supported fix when desktop, Start menu, or taskbar icons behave incorrectly.
   • Open Task Manager with Ctrl + Shift + Esc.
   • In Processes, find Windows Explorer.
   • Right-click Windows Explorer and select End task.
   • In Task Manager, select File > Run new task.
   • Type cmd.exe and create the task with administrative privileges.
   • Run:

          CD /d %userprofile%\AppData\Local
          DEL IconCache.db /a
     

   • In Task Manager, select File > Run new task again.
   • Type explorer.exe and press Enter.
   Note: save open work first, because Windows Explorer must be restarted.
3. Optimize virtual memory settings If the desktop starts lagging or becoming unresponsive when multiple desktops are open, check the paging file setting:
   • Open Control Panel.
   • Go to System and Security > System > Advanced system settings.
   • On the Advanced tab, under Performance, select Settings > Advanced.
   • Confirm Adjust for best performance of is set to Programs.
   • Under Virtual memory, select Change.
   • Make sure Automatically manage paging file sizes for all drives is selected.
   • Select OK > Apply.
   • Restart the PC.
4. Run Disk Cleanup Freeing resources can help if Explorer is becoming unstable:
   • Search for Disk Cleanup.
   • Select a drive and choose file types to remove.
   • Empty Recycle Bin only if nothing important is needed.
5. Run the System Maintenance troubleshooter
   • Open Control Panel.
   • Set View by to Large icons or Small icons.
   • Go to Troubleshooting > View all > System Maintenance.
   • Select Next and, if prompted, Try troubleshooting as an administrator.
6. Check for corrupted system files Microsoft recommends using System File Checker when File Explorer does not open or start correctly.

If the issue started after a Windows update, install the latest available Windows updates because Microsoft has previously shipped fixes for virtual desktop and desktop rendering problems through updates.

Also, if Sysinternals Desktops is being used instead of the built-in Windows virtual desktops, that tool has design limitations: windows cannot be moved between desktop objects, most tray applications appear only on the first desktop, and the recommended way to exit it is to log off.

• Mouse actions are blocked when you create a new virtual desktop
• Desktop isn't shown correctly when network icon in notification area is changed repeatedly in 64-bit version of Windows
• Fix File Explorer if it won't open or start
• Application shortcuts on the desktop, Start menu, and taskbar show blank icons
