What are these Office 365 URLs about?

Admin Portal Home: https://portal.office.com/adminportal/home

Under that, the different Admin Centers’ URL naming convention is in a quite mess.

Exchange is https://outlook.office365.com/ecp/?rfr=Admin_o365&exsvurl=1&mkt=en-US&Realm=yourcompanyname.onmicrosoft.com

Skype for Business is https://adminca1.online.lync.com/lscp/?language=en-US&tenantID=yourtenaneid

SharePoint is https://yourcompanyname-admin.sharepoint.com/

Under SharePoint, there is an OneDrive document repository for every user: https://yourcompanyname-my.sharepoint.com, it actually resolves to https://yourcompanyname-my.sharepoint.com/personal/yourname_yourcompanyname_onmicrosoft_com/_layouts/15/onedrive.aspx. Other than that, there are sites and teams, and the new stuff – groups.

Default site collection: https://yourcompanyname.sharepoint.com/

Sysprep doesn’t work on Windows 10

I was just trying to make a few Windows 10 VM images, so I started to use the same old tool: Sysprep. To my surprise, it didn’t work, while there’s no problem a few days ago on Windows Server 2012 and 2008. This time on Windows 10, it gave this pop up after I ran the same command (in my previous blog).


The log stopped after showing these lines:

SYSPRP Entering SysprepGeneralizeValidate (Appx) – validating whether all apps are also provisioned.
SYSPRP Package Windows.MiracastView_6.3.0.0_neutral_neutral_cw5n1h2txyewy was installed for a user, but not provisioned for all users. This package will not function properly in the sysprep image.
SYSPRP Failed to remove apps for the current user: 0x80073cf2.
SYSPRP Exit code of RemoveAllApps thread was 0x3cf2.
SYSPRP ActionPlatform::LaunchModule: Failure occurred while executing ‘SysprepGeneralizeValidate’ from C:\Windows\System32\AppxSysprep.dll; dwRet = 0x3cf2
SYSPRP SysprepSession::Validate: Error in validating actions from C:\Windows\System32\Sysprep\ActionFiles\Generalize.xml; dwRet = 0x3cf2
SYSPRP RunPlatformActions:Failed while validating Sysprep session actions; dwRet = 0x3cf2
SYSPRP RunExternalDlls:An error occurred while running registry sysprep DLLs, halting sysprep execution. dwRet = 0x3cf2
SYSPRP WinMain:Hit failure while pre-validate sysprep generalize internal providers; hr = 0x80073cf2
SYSPRP Shutting down SysPrep log

So I did a little research, found the thread in this forum is quite interesting.


and this as well


Anyway, after tried a few easy steps, I gave up. I don’t really need to clone a bunch of Windows 10 machines, besides install a new Windows 10 client is pretty easy and quick after the evolution of so many generations of Windows.

This issue seems to me a bug in the recent creator update. Microsoft has been trying to unify all its platforms – desktop, surface, phone, even server, but it is still far from there, this time these are a few dev leftover in a public release.

This is a MVA link to a number of free Microsoft Press books, but it hasn’t been updated since a year ago, kind of outdated: https://mva.microsoft.com/ebooks.

I would recommend this link from Eric Ligman, updated every summer, huge number of books, there is even a PowerShell script that you can download them all at once: https://blogs.msdn.microsoft.com/mssmallbiz/2017/07/11/largest-free-microsoft-ebook-giveaway-im-giving-away-millions-of-free-microsoft-ebooks-again-including-windows-10-office-365-office-2016-power-bi-azure-windows-8-1-office-2013-sharepo/
