Copy and paste not working in Windows?
Start with a harmless test word in Notepad: select it, choose Copy from the menu and paste it onto a new line. Then compare Ctrl + C and Ctrl + V. This separates a shortcut problem from an app or content-type restriction before you change settings.

Safe checking order
- Save unfinished work. Test with the word test, not a password, personal details or an important file. Use Copy, not Cut, so the original stays in place. This guide covers a local Windows 11 computer; workplace and remote-session policies may restrict transfers.
- Open Notepad and type test. Select the word with the mouse and use Copy in the right-click or Edit menu. Move the cursor to an empty line and choose Paste. Check that test appears, not something copied earlier. Make sure the destination is an editable text field rather than a page you can only view.
- Repeat using Ctrl + C and Ctrl + V. If menu commands work but the shortcuts do not, the clipboard works in at least this test. Check that the correct window is active and the text selected. Try the other Ctrl key if available. Do not indiscriminately remove accessibility settings you rely on.
- Compare another familiar app using the same test word. If the Notepad-only test works but one site or app fails, focus on that destination. A greyed-out Paste option can indicate an unsuitable target or an app restriction. Pasting a picture, a file and plain text are different operations: a text field may not accept a picture. If only formatting is wrong, try the app's own Paste as plain text option where available.
- Windows + V opens clipboard history, a separate optional feature. Empty or disabled history alone does not prove that ordinary copying is broken. Do not enable cloud sync just for this test. If history is already enabled, open it away from other viewers: it may show previously copied information.
- For a problem limited to one app, save your work, close the app normally and reopen it. If menu-based copying of harmless text fails in several local apps, save all work and restart Windows normally. Copy the test word again afterwards. The clipboard is not a saved document; restarting clears ordinary clipboard history except pinned items.
Symptoms and possible causes
JVS Tuki comparison: menus work, shortcuts fail → check selection, focus and keys; only one app fails → investigate the destination or app restriction; text works, pictures fail → check supported content types; several local apps fail → save work and try a normal restart. Old text appearing is a reason to verify the copy, not proof of a particular Windows defect. This is a practical isolation test, not an automatic diagnosis.
What not to do
- Do not cut an important file as a test or delete the original before checking the copy.
- Do not run unknown clipboard repair commands, edit the registry, disable protection or install a random clipboard manager.
- Do not post clipboard contents or screenshots in a public discussion. Do not bypass workplace transfer restrictions.
When to stop
Stop if a workplace security message blocks the transfer or the problem involves a remote desktop. Ask the administrator. If several local apps still fail after a restart, record the app names and menu-versus-keyboard test results for support, without including the actual content. If an original file is missing, do not continue transfer experiments with the same material.
