Windows 10 November Update Leaves 20GB of Update Files Behind

The Windows 10 November 2015 update was a full upgrade, and in the process it stored a backup copy of the prior version of Windows 10 on your disk. And that’s a good thing … as it allows you to restore back to the prior version of Windows 10.

But that backup copy is taking up 20GB or more of disk space on your system C: drive.

imageIt doesn’t hurt to leave it there.

But once you have been running with the updated Windows 10 for a few days, and things are running well, you may wish to reclaim that 20gb of disk space. You can do so in three easy steps:

  1. Startup (run) Disk Cleanup
  2. Select Cleanup system files
  3. Select to remove Previous Windows installations

Step 1: Run Disk Cleanup

You can start Disk Cleanup by typing in disk cleanup in the I’m Cortana. Ask me anything. search box at the bottom your Windows 10 desktop. Select to open up the Disk Cleanup desktop app, and select your system C: drive.

Optionally, you can right click on your C: drive from File Explorer, select Properties, and click on the Disk Cleanup button.

imageStep 2: Select to Cleanup system files

When the Disk Cleanup window display, on the bottom left, click on the Cleanup system files button.

Wait a few seconds while it rescans your disk drive.

imageStep 3: Select to remove Previous Windows installations

It will refresh the list of files that you can select to delete. Scroll through that list and look for “Previous Windows installations”.

On my computer, this was taking up 23GB of disk space.

Click to select this option, and then click OK.  It will then display a final “are you sure” message box. If you wish to proceed, click Yes.

That’s it!

New Ransomware Prevention Kit Coming Soon

Back HomeAmy Babinchak, President of Third Tier, has announced that they will be releasing an updated version of their Ransomware Prevention Kit next week. 

Two years ago (October 2013), Amy and her team led the way in providing a solution to help block the CryptoLocker attacks that were causing havoc worldwide (see blog post).

A lot has changed in the past two years, and such threats can still do great harm and damage for both individuals and businesses. Thanks to Third Tier, I sleep better knowing that my systems are protected.

Finally, Third Tier wants to reach out and encourage more women to get certified and work in the I.T. field, and is using this new Prevention Kit to raise money for this effort!

Windows 10 First Major Update

Microsoft announced the release of the first major update to Windows 10.

imageIn prior terminology, we would be calling this Service Pack 1, but Microsoft want to simply refer to it as the November 2015 Update. During pre-testing phase it was referred to as TH2.

This update will be pushed out automatically through Windows Update.

It contains a slew of new new features and improvements, including

  • Improved boot time (30% faster than Windows 7 on the same device)
  • Cortana and Microsoft Edge enhancements
  • New Windows Update for Business and Windows Store for Business services
  • Mobile Device Management
  • Azure Active Directory Join
  • and more!

Outlook Crashing after Latest Updates–KB3097877

I am seeing many reports today of Outlook crashing after the recent set of Office 2010 updates, as well as getting a blank screen after pressing CTRL-ALT-DEL for the login screen.

It appears that KB 3097877 may be the cause. If so you can try uninstalling that KB patch.

There is also a suggestion to clear the Java cache. Instructions can be found here:

MVP Summit 2015 Wrap-Up

I returned home Thursday evening from this year’s Microsoft MVP Summit in Bellevue WA. Due to non-disclosure agreements, I am not allowed to go into detail about what was presented or discussed. But I can tell you it was a great opportunity to meet with Microsoft product teams and spend time talking with fellow MVP’ers, some whom I have known for 12 years or longer.

My MVP designation is for Windows Server Small and Medium Businesses (WSSMB), so most of my attention was focused on server related topics. But I also had opportunities to learn more about Windows 10, Office, and the new Surface Book that was just released in October.

The weather was a mix of rain, clouds  and some sunshine. In Florida we do not really experience the changing colors of the seasons, so it was very enjoyable to see the yellow and red and orange colors in the trees while walking around the Microsoft Campus.


On a travel note, I was able to fly Alaska Airlines which now has a non-stop flight from Tampa to Seattle – less than 6 hours. Yea!!! The flight on Sunday left Tampa at 6:10pm and landed in Seattle at 9:25pm (which is after midnight Tampa time). The return flight left Seattle at 8:40am, and arrived in Tampa at 5:09pm.

Attending Microsoft Global MVP Summit 2015

I will be attending the Microsoft MVP Global Summit from November 1-5, 2015. This will be my 12th Summit, and I look forward to renewing contacts with other MVPs, as well as Microsoft product managers, and to provide feedback on Microsoft products and technologies.

Details as to what will be presented and discussed is under strict NDA (non-disclosure agreement), so I cannot share any such information. More later!

Splashtop Business New Enhancements

Back in January 2015 I started testing and using Splashtop Business as a remote control/support replacement for LogMeIn, which was getting too expensive for me. Splashtop is not my primary remote control solution, but I needed an alternative to LogMeIn for specific on-demand situations.

For the most part, I have been very happy with Splashtop. It does what I need it to do —

  • Easy setup to remote control into a user’s computer
  • Provides built –in file transfer capabilities
  • Supports mutiple monitors (on remote side)


And with their Version 3.0 release which just came out, they now support multiple concurrent connections, and have redesigned the Splashtop Business window interface for easier use.

My only complaint with Splashtop had been some occasional slow performance when remoting into servers. We resolved that issue earlier this month (see blog post).

It doesn’t have all the bells and whistles with products like ScreenConnect, LogMeIn Central, and others – but the price is right ($60/year) for my needs!


Windows 10 Phone Update

I have been using a Lumia 920 phone for almost 3 years now, and love it, in spite of a few quirks. I have been anxiously awaiting news of a Windows 10 phone.image

On the heels of releasing Windows 10 operating system back in July, Microsoft did announce the Microsoft Lumia 950/950XL Windows 10 phones. Both phones will come with a 20-megapixel camera. The 950 will have a 5.2” screen size, and the 950XL will be 5.7”. AT&T has already announced that will carry the phone.

However, availability of these phones are still up in the air.

But wait … there’s more!

Surface Phone Next?

News is slowly coming out that Microsoft may release a new Windows Phone next year that may be marketed as a Surface Phone, rather than a Lumia. Attachments could include a pen and a mini-attachable keyboard.

KB3093266 Windows 10 Cumulative Update Error 0x80004005

Here’s how I fixed the 0x80004005 error when trying to install KB3093266 —

First, I’m still getting used to the Windows Update interface in Windows 10. If you don’t know how to get to it, click on the Windows icon in the lower left, then click Settings, and in the window that displays, you can click on Update & security.


This morning I ran Windows Update on my computer. I clicked to select (check) the “Check online for updates from Microsoft Update” and then clicked the “Check for updates” box.


It identified a Cumulative Update for Windows 10 – KB 3093266, which it tried to install. However, the update process failed, giving me the 0x80004005 error.


I was able to fix it so it would install with these steps:

  1. Click inside the “Search the web and Windows box”, type services.msc and press Enter.
  2. Locate and stop the Windows Update service
  3. Leave this window open, and meanwhile …
  4. Open up a File Explorer window, and drill down to C:\ –> Windows –> SoftwareDistribution –> Download
  5. Delete everything inside the Download directory, but don’t delete the actual Download folder
  6. Now flip back to the Services window, and click to restart the Windows Update service
  7. You should be able to go back to Windows Update, select and install KB3093266  without having to reboot your computer.

Obviously, YMMV …
