256986 Description of the Microsoft Windows Registry
If you use the following method to copy a whole sheet in Excel 2002, the CPU utilization may reach 100 percent, and it may take a long time to complete the requested action:
  1. Right-click a sheet in Excel 2002.
  2. Click Move or Copy.
  3. Click to select the Create a Copy check box.
  4. Click OK.
This problem occurs because Microsoft Excel first saves the sheet in BIFF format to a memory-based docfile, and then loads it back through the regular load code when it copies all of the sheet. This process should work well, but when the sheet is large, the system needs to repeatedly reallocate and copy memory as the docfile grows (up to 40 or more megabytes (MB) in memory). This is what causes the requested action to take a long time to complete.
