How do I turn off the end of support banner in office 2010 permanently? (Office 2010, Windows)

The article is talking about the registry. You have to open the registry editor, ie run "regedit". That is where you will see "computer" at the top of the list of keys.

Can a non-IT person do this without, say, falling into the Matrix? :D 

Yes, but ...

.

The registry is key to the functioning of Windows.

The part of the registry you would be working on related specifically to Office.

So as long as you carefully follow the instructions and don't mess with anything else, don't accidentally change or delete any other keys, you should be OK. ...

.

Everyone has to start somewhere. And while worst case problems in the registry can be catastrophic, ie Windows won't run at all, in this case that is unlikely in the extreme.

.

The actual mechanics of doing registry changes is trivially easy, as long as you get them right:

• change value of existing key
• delete key
• add key

That basically sums it up.

.

Just be very clear on the instructions before you start (ie ask questions before you start) and follow them.  Feel free to ask specific questions if you encounter any problems along the way.

.

It wouldn't hurt to do some googling to find instructions/guidance on editing the registry.  User changes to the registry are known colloquially as "registry hacks" (search for that too).  Some of the hacks should tell you how to 'export' part or all of the registry.  Starting by exporting the "Office" specific registry key would give you a fall back position to undo any mistakes. You just import the export to undo your mistakes.

HKCU is programmers abbreviation for HKey_Current_User

• H=Hive (a collection of registry entries)
• K= Key
• CU = Current User

That is the registry key currently being used. That is where the OS looks to find registry settings. If you use the OS to make changes, this is where the changes are written

The .Default user is the template MS uses to create new user keys.  The rest of the keys under HKey_Users are generated by Windows as new userids are created.  They are typically MS cryptic

This article provides some information about the subkeys under HKCU:

There are many useful additional links about the registry at the bottom of this page.

When you sign in to Windows with a specific Windows userid, that tells Windows which specific sub key under HKey_Users to copy from into HKCU.

At the end of the Windows session, part of the shut down process copies the values under HKCU to the specific

HKey_Users subkey.

One of the sub keys under HK_Users is for the admin account (I think it is S-1-5-18 on all machines).

This article tells you how to identify the specific user/user ID for each of the HK_Users subkeys

How do I get to "Computer" on a Win10 computer? I only have This PC and from there, I can't seem to navigate or even find in search anything with the words "HKEY". I have installed the student version of MS Office on my computer. Thanks!

i have an idea no one's mentioned yet. what if i uninstalled the last update. it seems to me, one of the last updates likely contained the code for that annoying banner. sure, you might lose some security fix, but ... it's not supported anymore anyway, so you will have more of those coming soon in the future. plus, i use malwarebytes that has an anti-exploit feature that specifically protects ms office from nasties.
