Copy and paste stopped working

Copy and paste failing usually means the clipboard manager got stuck or a specific app is blocking clipboard access, not a system-wide fault. Restarting the affected app or the clipboard service resolves most cases.

Symptoms

  • Ctrl+C/Ctrl+V or Cmd+C/Cmd+V does nothing
  • Paste option greyed out in right-click menu
  • Copy works in one app but paste fails in another
  • Clipboard history shows nothing after copying

Likely causes

  • CommonClipboard manager app malfunctioningThird-party or built-in clipboard history tools can get stuck and block normal copy-paste.
  • CommonApp-specific restriction on pasting formatted contentSome apps block pasting rich text or images by design, requiring paste-as-plain-text.
  • PossibleStuck background process holding the clipboardA frozen app can lock the clipboard and prevent updates.
  • PossibleRemote desktop or virtual machine clipboard sharing disabledCopy-paste between a local and remote session needs a setting enabled.
  • Less commonKeyboard shortcut conflict from another appAnother program may have remapped the copy or paste shortcut.

What to do

  1. Try copying and pasting plain text into Notepad or TextEdit to isolate whether the issue is app-specific.
  2. Restart the app where pasting is failing.
  3. Disable any third-party clipboard manager temporarily to test.
  4. Restart the computer to clear a stuck clipboard process.
  5. If using remote desktop, check clipboard sharing is enabled in its settings.
  6. Try the paste-as-plain-text option (often Ctrl+Shift+V) if regular paste fails.

When to call a pro

If this happens only during remote desktop sessions, check with your IT department about clipboard redirection settings.
