Hello! Here is my problem. The window titles no longer display in the taskbar. This means I have to navigate between different windows using the Task Manager.
I would like to know the cause of the problem and of course the solution. Thank you in advance.

I have solved the problem. Thanks to Mrihon, here is the solution:

1) By pressing Ctrl+Alt+Del simultaneously, access the Task Manager.

2) Select the process explorer.exe, then click the End Process button.

3) Click on File/New Task (Run…).

4) In the Open text box, type regedit and confirm by clicking OK.

5) In the Registry, delete these four keys:
- HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\StuckRects2
- HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\StreamMRU
- HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Streams\Desktop
- HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\Explorer Bars\{32683183-48a0-441b-a342-7c2a440a9478}\BarSize

6) Open HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer.

7) Check that none of these DWORD values contain the number 1 as the value data: NoBandCustomize - NoMovingBands - NoCloseDragDropBands - NoSetTaskbar - NoToolbarsOnTaskbar - NoSaveSettings - NoToolbarsOnTaskbar - NoSetTaskbar - NoActiveDesktop - ClassicShell

8) Open HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Group Policy Objects\LocalUser\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer.

9) Check that a DWORD value named NoCloseDragDropBands indeed has the number 0 as the value data.

10) In the same tree, delete a DWORD value named NoMovingBands.

11) Open HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion\Winlogon.

12) Ensure that the String value Shell only contains this in the Value Data text box: explorer.exe.

13) Open HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\Explorer Bars\{32683183-48a0-441b-a342-7c2a440a9478}.

14) Delete a binary value named BarSize.

15) Go back to the Task Manager, then click on File/New Task (Run…).

16) In the Open text box, type explorer, and then confirm by clicking OK.

Good evening Adkiks
Thank you very much for the explanations regarding the disappearance of the windows from the taskbar. I applied the method, with some fears, I must admit, as modifying the registry is not my strong suit.
However, I encountered a problem, which seems to have no consequences for now
Steps 8, 9, and 10 did not yield the expected results:

8) Open HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Group Policy Objects\LocalUser\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer.

9) Check that a DWORD value named NoCloseDragDropBands indeed contains the number 0 as its data.

10) In the same tree structure, delete the DWORD value named NoMovingBands.


I did not find the Group Policy Objects key.
After noticing the windows reappearing, I went back into regedit to check if, by chance, Windows had recreated this key and all its content. I found nothing.
Should I do something?
Thanks in advance for any additional advice.
