Excel opens 2 or more separate windows at the same time

1. First Win7 version click "Start" menu, enter "Regedit.exe" in the input box to open the registry

2. Then locate the path HKEY_CLASSES_ROOT \ excel.sheet.12 and Hkey_classes_root\excel.sheet.8.
3. Here first change the HKEY_CLASSES_ROOT \ excel.sheet.12 inside the registry, open Shell\open

   Delete the Ddeexec folder inside, then open the Command folder and double-click the registry command inside.

   Change the file inside to read as follows: XB ' BV5!!!!!!!!! Mkkskexcelfiles>vijqbof (Y8 ' w! Fid1glq "%1"

   Copy and paste directly to save.

   followed by the same method to Excel.Sheet.8 inside Shell\open

   Delete the Ddeexec folder, and then also modify the registry file in command:

   XB ' BV5!!!!!!!!! Mkkskexcelfiles>vijqbof (Y8 ' w! Fid1glq "%1"

   The content of the modification is the same as excel.sheet.12.

   Note: Smart netizens will find, in fact, the two code differences in the end, the simplest and no problem is: double-click Command, just want to change the end of the/dde to "%1", do not need to copy the past, Sheet8 and sheet12 the same. In this way, there is no "only valid for the current product" issue.

   (because everyone's office version may be different, D or Z version also has the difference, only to change the last/dde is safe, again this thanks long464882031)
