Hi there - I have tried the method 1 'troubleshooting' in your reply. Upon selecting Troubleshooting, a full-screen app opens with a magnifying glass in the centre, and then immediately minimizes to the taskbar. Reopening it will only stay open for a second
or so then it minimizes again.
Edit: I notice that the above also happens when I try to open the 'Feedback' app - it opens for a second then minimizes.
Also, the original KB302538 update is no longer offered as an update. Checking in the list of updates installed, however, it isn't there. So it now appears I won't be able to install this update.
The update KB3025380 makes one change in the registry that enables you to upgrade to the next build of the Tchnical Preview.
Right Click the Start button and select Control Panel.
In Control Panel, on the left side of the window, select the View Update History item.
Look in that list of updates for the Windows Technical Preview December Update KB3025380
Look in the Status column to see if it shows Succeeded or
Failed. If it shows Failed look for other entries that may show
Let us know what you find.
