Pressing the Win+M key combination in Windows 10 can quickly minimize multiple document windows opened by the Word application. However, when we double-click another Word document icon to open a new window, all Word windows that have been minimized automatically switch to maximize mode (Figure 1). This problem is caused by the Word program startup mode, the use of the Registry Editor, you can prohibit the occurrence of this situation.
The same thing happens in Windows 10 when you open multiple document windows with Excel, PowerPoint and other Microsoft Office applications.
First, press Win+R to open the “Run” dialog box, type REGEDIT and click “OK” to open the Registry Editor (Figure 2).
In order to avoid accidental modification and facilitate system recovery, you can first execute the “File→Export” menu command in the Registry Editor, select the export range as “All” and save the registry backup (Figure 3).
Next, start modifying it. In the left pane of the registry window, navigate to the following path “HKEY_CLASSES_ROOTWord. Double-click the “(default)” item in the right pane, you can see the “(default)” string value of the “numeric data” for “”C: Program Files (x86)Microsoft OfficeRootOffice16WINWORD.EXE” /n “%1” /o “%u”” (Figure 4).
At this point, we need to add the “/q” switch to the end of this numeric data to make it a command like this (Figure 5)
“”C:Program Files (x86)Microsoft OfficeRootOffice16WINWORD.EXE” /q /n “%1” /o “%u””
Click “OK”, exit the Registry Editor and restart the computer.
After completing the above changes, Word multi-window automatic maximization of the problem will no longer occur. Other Office components are modified in a similar way to Word.
