Who installed Microsoft Office 365 on my PC on Tuesday September 19, 2023?

[Oscar Mayer]

Please see image file: [https://i.postimg.cc/Z5NLdy93/msoffice365.jpg]

I needed to uninstall an unrelated program using Revo Uninstaller 2.17
when I noticed that Microsoft Office 365 was "installed" on my single-user
desktop PC on Tuesday the 19th of September, 2023 (I'm the only user).

But I already have Microsoft Office 2007 installed for a dozen years,
and it works just fine on my PC (which was a high-end PC at the time).

I never wish to "subscribe" to any product that doesn't provide a
single-user "permanent" license - so certainly I didn't add this.

Who did?

Many versions of Windows come with a 30 day eval of Office, that remains
installed even if you install a fukk version of Office.

Possibly Microsoft updated the eval software (bugs? shiny new icons?)

From the name ending with __8WEKYB3D8BBWE it appears to be a Store app

You sure MS Office (the suite) is installed? In Windows 10, Microsoft
bundled their Office Live app, and added a tile to the Start menu. They
rebranded it to Microsoft 365. It is just a web-centric app to
interface with your Microsoft account, if you have one, to use the free
MS Office 365 Online apps.

https://www.microsoft.com/en-us/microsoft-365/free-office-online-for-the-web

These web apps do not have the full feature set of the installed Office
product. Well, they're web apps, and they're free. In Revo, notice the
size of the "Microsoft 365 (Office)" product is a mere 8.84 MB.
Obviously the full Office suite is not going to be so puny.

Microsoft 365 (Office)
https://apps.microsoft.com/store/detail/microsoft-365-office/9WZDNCRD29V9

File you create with the online web apps are stored in your MS OneDrive
online file storage quota (5 GB to start, pay for more). I never used
this app other to to find out what it did. I don't remember if it
allowed your data files to be stored locally, or if you had to initiate
a download from your OneDrive account to your computer. If you have the
OneDrive client installed on your computer, you can configure that
online files get synchronized to your computer.

Revo does not show the actual install date when a product was /first/
installed. The install date it shows could be an update. Some updates
are not incremental. Instead the entire product is installed atop the
existing installation. So, Revo see an install date of when the update
got applied. Add/Remove Programs will do the same: if the product's
upgrade was actually a full install, it shows the new date. I've had
the standalone MS Office Pro Plus 2021 installed since Nov 2022. I had
MS Office 365 before, but let its license lapse and removed the suite
about 3 years ago. I hit so many deficiencies with Libre Office that I
went back to MS Office. Apparently there was an update today which both
Windows and Revo thinks is a full install, so they list today as the
install date.

I think the install date is based on when the uninstaller was added to
the registry (the uninstaller is usually the installer program that uses
the install log to remove the program). The uninstall tracking is at:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall

For my standalone Office 2021 install, there is a subkey under there:

ProPlus2021Retail - en-us

but it doesn't have an install date. It uses the Click-To-Run scheme,
and:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\{90160000-007E-0000-1000-0000000FF1CE}

shows an install date of 20230917 for the Click-to-Run licensing
component. Not all uninstall entries have the product name. A GUID
might be used instead for the program.

When a program gets updated, that could reflect its install date. The
original install date gets stepped on.

Not to be snarky, but my first guess is that Microsoft did, "to
enhance your user experience" as well as increase their cash flow.

I got a different sized one, and I can see it in the Installed Apps list.

An Agent Ransack search, shows bits of stuff in a WinSxS WindowsCommunications
area, implying it could be part of an advertising campaign.

Perhaps the thing you see, is a "fresh set of images" for the advertiser.
It might be tied into a MSEdge:Bing attack of some sort.

In its current form, unless it was the "web flavor" of office,
it could well be harmless. You can edit documents on the web,
if you're happy to share your document content with Microsoft.

You might also look at the hidden file WindowsApps in Program Files. MS
Photos has turned up there.
More difficult to get rid of than 365 Office was.

What is the size of the folder which it is installed in the Programs
folder. Is it large enough for a full installation of MS 365.

MS has been playing with people's minds with the office suite. I
installed the MS Office to one of my computers. This is the non
subscription version. However when it is installed is carries the 365
designations. I have to be careful that MS does not convert me over to
the 365 subscription version.

More likely a app package for the subscription product not a full install.
Look on your Start Menu list for Microsoft 365
- the app package can be removed/uninstalled

I can only see two flavours of artifact in there.

To get a better picture, I'll need to mount a Macrium Backup with restricted access removed.

The titlebar.js contains:

var url = new URL(document.documentURI);
if (url.host != 'www.office.com' && url.host != 'www.microsoft365.com') {
ControlsOverlay.showSeparateHeader();
ControlsOverlay.insetCompleted = false;
}

We can't really tell from "WebView2Loader.dll" whether that's for html/js application execution,
or it's for web viewing as such. I'm going to guess it's a web navigator of some sort.

This suggests it is the free web-based office version.
