"Compatibility Mode" was a new feature introduced by Microsoft in Office 2007 version. It was developed to support old documents and files which were created using previous versions of Office suite such as Office 2003, etc. When you try to open a document created in older version of Word in a new version of Word program, the document window shows [Compatibility Mode] text in titlebar as shown in following screenshot:
If you are also facing this issue, following methods will definitely help you in fixing it:
- METHOD 1: Using Microsoft Word Options

METHOD 1: Using Microsoft Word Options
- 1. Open Microsoft Word, click on File Menu or ORB and then click on Options.

METHOD 2: Deleting Default Document Template
In such situation, you'll need to reset the default template for creating new documents using following steps:
- 1. Type %appdata%\Microsoft\Templates in RUN dialog box and press Enter. It'll open Templates folder in Windows Explorer.
- 2. Look for Normal.dotm file in the folder. Either delete the file or rename it to some other name.
- 3. That's it. Open Word and it'll automatically create a new Normal.dotm file in Templates folder which will solve the issue.
METHOD 3: Using Registry Editor
If above mentioned 2 methods don't work for you, here is a Registry tweak to fix the issue:
- 1. Type regedit in RUN dialog box and press Enter. It'll open Registry Editor.
- 2. Now go to following key:
for Office 2007: HKEY_CURRENT_USER\Software\Microsoft\Office\12.0\Word\Options
for Office 2010: HKEY_CURRENT_USER\Software\Microsoft\Office\14.0\Word\Options
for Office 2013: HKEY_CURRENT_USER\Software\Microsoft\Office\15.0\Word\Options
- 3. In right-side pane, look for a DWORD CompatMode. If you find it, delete it. If it doesn't exist, create a new DWORD and set its name to CompatMode and set its value to 0
- 4. Close Registry Editor and restart Word. It should solve the problem.
