Frequently Asked Questions
Why does Windows say I have no internet when my web browser works?
Windows uses the Network Connectivity Status Indicator (NCSI) to verify internet access. If NCSI is blocked by a DNS issue or misconfigured settings, built-in apps like Office will assume there is no internet, even though standalone web browsers continue to work fine.
What is the WWAN AutoConfig service and does it affect Office activation?
WWAN AutoConfig is a Windows service that manages mobile broadband connections. Setting this service to 'Automatic' in the Windows Services app can sometimes resolve background network status errors that prevent Office from contacting activation servers.
Can I use WordPad instead of Microsoft Office if activation fails?
Yes, WordPad is a built-in Windows app that allows you to open and save basic text files. However, it lacks advanced formatting capabilities. For a full-featured experience, downloading a free suite like WPS Office is highly recommended.
Will an in-place upgrade delete my personal files?
No. A Windows 10 in-place upgrade is specifically designed to repair core system files and resolve deep network or corruption issues without removing your personal files, documents, or installed applications.
