I have this problem regularly, and I usually try to solve it by manually transferring my settings. I admit that this is pretty time-consuming, and I, too, would prefer having a tool that just does it for me. But on the other hand, it is a way solving the issue without the need of using third party software.
Here is what I do:
Description should work for Word 2010, 2013, 2016...
1) Search for the "Normal.dotm" file in the "ApplicationData... \Templates" Folder. For me, this is C:\Myname\AppData\Roaming\Microsoft\Templates, but the proper path may vary depending on your system, and so may the folder names (In German, e.g. it is not "Application Data/Templates" but "Anwendungsdaten/Vorlagen".) Copy the Normal.dotm file into the respective folder on your new machine. (It may take some time for you to find out what folder this is. And of course you need access to this folder. If you happen to work in a larger organisation, you may not have access to this folder. Sorry.)
2) In the same "Templates" folder, you will also find your Word document templates, e.g. for your official letters, serial letters or whatever, named xxxx.dot, e.g. OfficialLetters2016.dot or so. Copy those as well to the respective folder on the new machine.
3) Transfer your settings for the "Ribbon": File --> Options --> Customize Ribbon --> Import/Export (a button that is placed right hand side, to the buttom of the screen). This will let you save a file typcially called "WordCustomizsations.exportedUI". Save it somewhere (you may chose a different name, it serves only to be identified by you yourself), and transfer it to your new machine. There, you would open the same dialogue and choose "import" and point to your file.
4) You may have a number (quite a lot, maybe) of paragraph styles that you are used to use. To transfer them, create a new Word document (it may be an empty one, just a blank sheet of paper), save it and transfer it to your new machine. There, open it. Then search for the "Manage Styles" function. (It may not be available in your ribbon; then, search for e.g. via Files --> Options --> Customize Ribbon --> Choose commands...) The "Manage Style" dialogue, with its "Import/export" button opening an "Organize" dialogue, lets you list the styles stored in one document and copy it over to another document, or - which is what you want - into the Normal.dotm file.
Note: Step 4 should actually be unnecessary if you succeed to copy your Normal.dotm onto the new machine. If not, Step 4 gives you an option to copy your styles anyway. However, you will not be provided with all the shortcuts you are used to. These you will have to create from scratch (if you could not copy your Normal.dotm).
5) You may have a number of Word macros (i.e. VBA scripts) that help make your working day a more joyful or easy one. To copy these, you have to open the Visual Basic Editor (via the "Developer" section of the Ribbon; if you do not see this, you probably do not use such fancy stuff as macros anyway), browse there for the "Normal" section, and therein, copy everything which seems to be personally yours, with special respect to the "Forms", "Modules" and "ClassModules" folders. Unfortunately, you cannot copy all files at once. You have to right-click every single file separately and choose "Export" from the context menu. This then will save the file as a .frm, .frx and .bas file into a location you choose. Copy all those file to your new machine, and import them to the proper place (again "Normal" section in the Visual Basic Editor) by choosing "Import file" from the context menu.
Note: I am not sure anymore if Step 5 would not be already covered by copying Normal.dotm onto the new machine. I am tending to believe that it doesn't, but give it a try, and if your various macro modules are already there, be happy, because you are lucky.
6) You may be using customised AutoCorrect entries (having replaced the silly ones that Microsoft deliveres by default). You will find your AutoCorrect entries in a folder like C:\Users\YourName\AppData\Roaming\Microsoft\Office, in the form of a number of xxxxx.acl files. Copy them over to the respective place on the new machine.
7) You may have your own "User Dictionaries", i.e. files where Word stores all those word that you tell the spellchecker to be correct although it highlights them as wrong. (The more elaborate your language is, the more Word will think your spelling is wrong...). User dictionaries are stored typically in C:\Users[you]\AppData\Roaming\Microsoft\UProof, and are called something like CUSTOM.DIC or WHATEVERNAME.DIC. (This path is definitely so in Windows 10 and Office 2016 for other versions I did not check.)
Description should fit Excel 2010, 2013, 2016...
In Excel, the procedure is less time-consuming
1) Copy the Ribbon settings (similar procedure as above Step 3)
2) Similar to Step 5 above, copy your macro code (VBA), forms etc. from the Visual Basic Editor, section "PERSONAL.XLSB" to the same place on the new machine.
Here is yet one important thing to know: In a freshly set up system, you may not have a "PERSONAL.XLSB" file yet. This would typically be the case when you start working in a new organisation, and they have just created your user account. In this case, just pretend you want to record a macro (via the "Developer" tab in the ribbon, then "Record Macro"). This will create a PERSONAL.XLSB, where you then can also import your pre-existing VBA code (Modules) and form elements. With your macro modules copied into the new system, the shortcut keys you assigned to the macros, should be working, too.
Have fun and success, and enjoy your re-customized new office machine!

1) Macros: similar
2) Ribbon settings: similar
3) One more thing to do is to take care of archived e-mails. Archived e-mails typically are stored in a .pst file typically on the hard drive of the computer (but they can sit anywhere else too). To find out where they sit, click File --> Account settings --> Account settings (yes, twice) --> Data files. You should get a path displayed for archive files. Copy those files (it may be only one) to your new machine. Then tell outlook on the new machine where the archive file (I usually call it simply archive.pst) is stored, in the same dialogue.
3) E-Mail templates: like Word document templates (see above) these are in the same "Templates" folder as the "Normal.dot", i.e. typically C:\User[you]\AppData\Roaming\Microsoft\Templates, and you copy them into the respective folder on the new machine. These template file are called xxxxxx.oft

1) Macros: much to my disappointment, OneNote does not have the option to improve it by self-made VBA macros. :-(
2) Ribbon-settings: as in Word and Excel
3) Copy your notes. They may be stored in one xxxxx.one file, or in several of them. You can check their location via File --> Options --> Save & Backup. The dialogue window will show where those files sit, and you can then access them via your favourite "Windows Explorer" replacement (I strongly recomment Xplorer2 by Zabkat)... or of course via "Windows Explorer" itself (if you have masochistic tendencies).
