A few days ago, Excel started behaving rather strangely on my computer. I could copy a cell normally — the usual moving dashed border appeared around it — but nothing happened when I pressed Ctrl + V.
There was no error, warning or sound. It simply wouldn't paste.
The strange thing was that the Windows clipboard did work. I could open it with Win + V and paste from there. Word and Notepad had no problem with Ctrl + V either.
Excel also wouldn't let me drag cells. The black cross appeared when I hovered over the corner of a cell, and I could drag it, but when I released the mouse button the cells remained empty.
I restarted Excel and the computer too, but the problem was still there.
If something similar happens to you, there are several very simple tests that can help you find out where the problem actually is.
After ruling out possible causes one by one, it turned out that Excel wasn't misconfigured and no add-in was interfering.
And of course, no key on the keyboard was stuck either (a very common issue, I have to say).
In my case, the problem had been caused by something that may well surprise you.
Here's the step-by-step process you can follow to fix it.
1. Check whether the problem is Excel or the Windows clipboard
The first thing is to test whether Ctrl + V has stopped working throughout Windows or only in Excel.
Copy any text and try pasting it into:
- Notepad.
- Word.
- Your browser.
- Another application.
If it works, the problem is with Excel.
Then, inside Excel, you can press Win + V to open the Windows clipboard history if you have it enabled.
Curiously, this test is very likely to work correctly in every case.
2. Check that Excel is actually copying the cell
Type anything in a cell, for example “123” without the quotation marks.
Select it and press Ctrl + C.
Excel should display around the cell the familiar dashed border that moves.
If it appears, Excel has indeed copied the cell and the problem occurs when it subsequently tries to paste it.
This distinction is important: Excel failing to copy is not the same thing as pasting failing.
In my specific case, the border appeared correctly, but Ctrl + V did nothing. In other words, pasting was failing.
3. Try other ways to paste
Before concluding that Ctrl + V is the problem, try the menu option Home > Paste.
And try it from Excel's ribbon itself.
Again, both methods will probably work, and the problem may lie with the Ctrl + V command. But there is another symptom too.
4. If you can't drag cells either, check this option
If your problem also affects dragging cells and they don't fill with what they should, go to File > Options > Advanced > Editing options and make sure this is enabled:
Enable fill handle and cell drag-and-drop
If it was disabled, enable it and try again.
To test the fill handle, type, for example, a 1 in a cell and place the cursor over the small square in its bottom-right corner.
A black cross should appear.
Drag it across several cells (down or to the right) and release the mouse button.
In my case, this option was already enabled. The cross appeared and I could even make the dragging motion, but when I released the mouse button, Excel did not change any cell.
That pointed to a deeper problem.
5. Try Excel in Safe Mode
Let's continue testing Excel. We're going to open it without loading most add-ins and customizations.
Close Excel, press Win + R, then type and run excel /safe.
Excel will open in Safe Mode.
Create a completely new workbook. Type something in A1 and test Ctrl + C and Ctrl + V, as well as dragging cells.
Two things can happen here:
If it works in Safe Mode
It's quite likely that an add-in or customization is causing the problem. You can review them under File > Options > Add-ins and, especially:
Manage > COM Add-ins > Go
Disable them temporarily and restart Excel normally.
If it still doesn't work in Safe Mode
Then the add-ins aren't the cause, which is exactly what happened to me.
6. Always test with a new workbook
More than a test, this is a piece of advice.
Open a completely new document and test the same operations there.
If the problem appears only in a particular file, you should investigate workbook-related issues such as:
- Sheet protection.
- Macros.
- Document-specific features.
- File corruption.
It doesn't happen often, but it's worth ruling out.
7. Check which version of Excel you have
At this point, it's worth checking whether the problem appeared after an update.
Go to File > Account > About Excel.
You'll see something similar to:
Microsoft Excel LTSC
Version 2408
Build 16.0.xxxxx.xxxxx
64-bit
Pay particular attention to the build.
In my case, I had:
Microsoft Excel LTSC 2024
Version 2408
Build 16.0.17932.20976
64-bit
And this is where the explanation finally appeared.
8. Some Excel updates can break pasting
Microsoft released an Excel security update on September 8, 2026, and acknowledges among its known issues that, in Excel 2024, 2021, 2019 and 2016, the paste operation may fail.
The symptom described by Microsoft is practically identical to what I was seeing: the user tries to paste, the source remains selected and the destination does not change, with no error message.
So, before reinstalling Office, check two things:
- When the problem started.
- Whether it coincides with a recent Office update.
If so, this becomes the most likely explanation.
9. Find the previous build for your version of Office
Find the previous build for your own Office edition and update channel.
Microsoft maintains update histories where you can check the builds released for Office 2024, LTSC and Microsoft 365.
My Office LTSC 2024 installation had the problematic build: 16.0.17932.20976.
The previous version available for my product branch was 16.0.17932.20910, released on August 11, 2026.
That's the version I rolled back to.
10. How to temporarily roll Office back to an earlier version
Sometimes an update introduces unexpected behavior. In that case, the sensible thing is to roll back to the previous version, first checking your installation type and the correct build for your Office installation.
First, close all Office applications you have open:
- Excel.
- Word.
- Outlook.
- PowerPoint.
- etc.
Then open Command Prompt as administrator and type:
cd /d "%ProgramFiles%\Common Files\Microsoft Shared\ClickToRun"
OfficeC2RClient.exe /update user updatetoversion=16.0.17932.20910
Replace the part shown in bold with your previous build number.
Office will download and install it; don't close the process while it is running.
When it finishes, open Excel and go back to File > Account > About Excel.
First check that the build number has changed. Once you've confirmed it, test Ctrl + V and cell dragging again. Normally, both should work again.
11. Temporarily disable updates
There is one final important step.
If you roll back to an earlier build but Office still has automatic updates enabled, it may reinstall the very version you just removed.
To prevent that temporarily or indefinitely, go to File > Account > Update Options > Disable Updates.
Microsoft also recommends temporarily disabling updates when doing this. It's up to you whether to enable them again in the future once an update fixes the problem.
Conclusion and summary: what to do if Excel won't paste or let you drag cells
If this happens to you, do the following in this order:
- Check Ctrl + V in Word and Notepad.
- Check Win + V.
- Copy a cell and verify that the dashed border appears.
- Try the Paste button and the menu option.
- Check that the fill handle is enabled.
- Open excel /safe.
- Repeat the tests in a new workbook.
- Go to File > Account > About Excel.
- Check whether the build matches a known problematic update.
- If it does, locate the previous build for your Office installation.
- Temporarily roll back to it.
- Disable updates until Microsoft releases a fix, then enable them again.
In my case, the whole clue was in one detail:
- Excel was able to copy.
- Windows kept the content in the clipboard and other applications could paste it.
So the problem was one hundred percent in Excel.
The problematic update explained why a program that had worked perfectly until the day before suddenly stopped working without me changing absolutely any settings.
Frequently asked questions
Why does Excel copy a cell but not paste it with Ctrl + V?
It can happen because the problem is in Excel itself rather than the Windows clipboard. One clear clue is that Ctrl + C shows the dashed border, but Ctrl + V does not change the destination cell.
How can I tell whether the problem is Excel or Windows?
Try Ctrl + V in Word, Notepad or your browser. If it works outside Excel, the problem is probably in Excel.
What does it mean if Win + V works but Ctrl + V doesn't?
It means Windows is correctly retaining the clipboard contents. The problem would be in how Excel executes the paste command.
Why won't Excel let me drag cells?
Check under File > Options > Advanced that the option to enable the fill handle and cell drag-and-drop is turned on.
How can I open Excel in Safe Mode?
Press Win + R, type excel /safe and press Enter. Excel will then start without loading most add-ins and customizations.
What does it mean if the problem disappears in Safe Mode?
Most likely, an add-in or customization is interfering with Excel. You can try temporarily disabling COM add-ins.
What should I do if Ctrl + V doesn't work in Safe Mode either?
Try a new workbook and check your Excel version and build. If it also fails there, a recent Office update may be the cause.
How can I find out which version of Excel I have installed?
Go to File > Account > About Excel. There you can see the installed version, build and architecture.
Can an Excel update stop pasting from working?
Yes. Some updates can introduce bugs that affect features such as pasting even if Excel was working correctly until then.
Can I roll back to an earlier version of Office?
Yes. On compatible installations, you can temporarily roll back to an earlier build using Office's update tools.
Should I disable updates after rolling back to an earlier build?
Temporarily, yes, because otherwise Office could automatically reinstall the problematic update.
Do I need to reinstall Office if Excel won't paste or drag cells?
Not necessarily. First, check the clipboard, fill handle, Safe Mode, a new workbook and the installed build.

I purchased Office 2024 a few days ago after experiencing this with Office 2021 so I uninstalled Office 2021 and reinstalled only to find that the key I thought was the correct one was not, hence the purchase of Office 2024/
However, Office 2024 does have the same problem and my problem is that I don’t have a previous version of Office 2024 which to roll back to.
Any suggestions?
Thanks
Hi Robin, I suggest you ask ChatGPT for the previous compilation number of your Excel version (give it you current number, easier with a screenshot) . Then try steps 10 and forward. Let me know if helps.
