Hi Dark Pumpkin,

I get exactly the same issue. Tons of googling don't get any luck.
This issue happened to me "silently" - until some day I copy a cell from a brand new Excel sheet, no newly installed applications, no changes to any configurations in the OS or Excel application, and it's even true when the issue happens 1 hours later after I did a full system image restoration. The same prompts (yes, 4 times) appears when copying/cutting/undoing via either shortcuts or menu selections.

Workaround is to enable Print Spooler service.

I confirm the following facts:

• I had a system image where this issue doesn't exist.
• As soon as I restored the system image, the issue doesn't exist (with Print Spooler disabled) as I tested.
• I started up the restored system and launched a few applications, including VMware Workstations v10, Putty v0.60, uTorrent 2.2.1, TeamViewer v9.0.26297, NotePad++ v5.9.8, Chrome v35 and a few other IM applications. I don't think it's anyhow related to those applications by the way.
• No other operations with my PC after I launched those applications until I get to my office when I use TeamViewer to do a simple copy/cut/undo actions - it happens.
• My OS = Windows 7 Ultimate x64 English and My Office version is 2010 x64 version.
• The issue doesn't happen to other Office applications but only to Excel.

So basically I think TeamViewer 9 triggered something deep in the system call or something that makes copy/cut/undo functions rely on Print Spooler service. When I get back to home and directly use my keyboard and mice, the issue persists without using TeamViewer. There must be some TeamViewer service running in the background but I can't tell if that's the cause. Anyway, once it happens, it persists.

I don't know if this thread has any update or not, but I'm leaving this message here to add my cents.

And Yes, I want to know how to resolve this. I don't have hardware resources issue (i7 3770 + 32GB RAM + 256GB SSD) but I just want to know why that happens so it's not about "saving resource by disabling Print Spooler".
