Please check the if Acrobat is updated to the latest patch or not.
You were experiencing this with Acrobat X as it is not a compatible version with Windows 10.
Also, if you see thumbnails, close them.
I have version 11.0.13. No updates are available for this version
Only the embedded thumbnails can be removed. I removed them but I still cannot delete pages.
I can delete a page only when I shut down Acrobat XI and restart Acrobat. But then the deletion of a page becomes impossible again if I navigate through the document or edit some text.
Disable the thumbnails view in Windows Explorer or close Windows Explorer.
I closed Windows Explorer and Windows 'Edge'. But this has not changed the situation. I still can delete a page only after shutting down Acrobat and restarting it. But the deletion becomes impossible again after I have navigated through the document .
