How to Fix Word Reverting to Word 2010 After a System Restart
Product
Microsoft Word
Device & OS
Windows
Scenario
Opening DOC or DOCX files from the file explorer or desktop after restarting the computer.
Observed behavior

Before you start

Verify that your newer version of Microsoft Office is still installed on your PC by checking your list of installed programs in the Windows Settings or Control Panel.

Solution 1Recommended

Set the Newer Word Version as the Default Application

Manually update Windows file associations so that DOC and DOCX files automatically open with your most recent Word installation.

When multiple versions of Office are installed on the same computer, Windows updates or restarts can sometimes confuse the file associations. Re-assigning the default app will permanently point your files to the newer software.

1
Open Windows Settings

Press the Windows key + I on your keyboard to launch Windows Settings, then click on 'Apps' from the main menu.

2
Navigate to Default Apps

Select 'Default apps' from the left-hand navigation pane, scroll down, and click on the 'Choose default apps by file type' link at the bottom.

3
Locate DOC and DOCX Formats

Scroll down the alphabetical list to find the .doc and .docx file extensions. Click on the current default program icon next to them (which likely shows Word 2010).

4
Select the New Word Version

From the pop-up list, select your newer version of Microsoft Word to assign it as the new default program for these document types.

Set the Newer Word Version as the Default Application
Verify the Change: Double-click any Word document on your desktop to confirm that it now successfully launches in your newer version of Word.

Frequently Asked Questions

Why did my computer randomly change my default Word version to 2010?

Windows updates, installing new software, or unexpected system reboots can sometimes reset file associations. If both Office 2010 and a newer version are installed on the same PC, they often compete for default status in the Windows registry.

Can I have both Word 2010 and a newer version installed at the same time?

Yes, but it is highly discouraged. Running multiple versions of Office on the same machine frequently leads to file association conflicts and licensing errors. It is best to uninstall the older version.

Will uninstalling Word 2010 delete my personal documents?

No. Uninstalling Microsoft Office 2010 only removes the application itself from your system. Your DOC and DOCX files are saved safely on your hard drive and will remain completely intact.

What should I do if 'Default Apps' doesn't show my newer Word version?

If your newer Word version is missing from the Default Apps selection list, perform an 'Online Repair' from the Windows Control Panel to forcefully restore its registry keys and file association capabilities.
