Look, don't listen to all the other nonsense. Office 2007 will still be fully updated by Windows Update with all the existing Microsoft Updates. even though its out of support life.
For anybody, all that you need to do is the following.
- Install Windows 10.
- Allow Windows 10 to install all of its Windows updates through Windows Update.
- Install Office 2007 (or any Microsoft office for that matter).
- Run Word or Excel and chose the option to allow Office updates through Windows Update.
5 Run Windows Update again
- You may have to run Windows Update a second time to get all the updates for Office
7 When you get the "Office 2007 File Validation Error 0x80240023" error, just let the computer sit powered on and connected to the internet for several hours, Over nights always works.
- The File Validation update will install by itself, after several hours, you will come back and be asked to continue and accept the update.
- THATS IT!! no other ****, just let it sit for a few hours and the failing update will install and the error will clear, and you will be good to go!!!
