Surface Detach Icon says Detached when it's not

Don't worry, the next step is basically running dism again. The only difference is, you let it search a windows image to locate the files it can't find on your SB anymore. Nothing too dangerous.

Well, I did as Matt’s post suggested: 

1. Right-click on the Windows Start logo > COMMAND PROMPT (ADMIN)
2. Entered this code where the cursor is flashing:  sfc /scannow(Came back with errors that could not be fixed.)
3. Entered Dism /Online /Cleanup-Image /RestoreHealth(Came back with Error code:  0x800f081f)

This is where I am... I'm not particularly happy or comfortable that I have to do this. But I guess I'll continue on with the other steps. I'll post again to let you know how it turned out. 

I have to admit, this Surface Book i7/512 right out of the box was very frustrating. I still may take it back. If this was a car, there would have been a major recall.

As far as the issues that I’ve faced thus far, Matt’s post on page 3 has helped quite a bit but there were other things I had to do to make things work pretty decently. Below is the same as he posted but I put it in outline form for easier reading. I entered the codes verbatim. For example, if there are spaces, forward slash vs. backslash, uppercase letters, etc.

Again, these are the things I did to get my SB up to par. I don’t know if it will fix your issues but…good luck.

1. Installed all current updates: Windows Start logo > Settings > Update & Security > Windows Updates > Check for Updates.
2. Restarted.
3. Removed Windows Hello from login: Windows Start logo > Settings > Accounts > Sign-in options > Windows Hello > Remove.
4. Restarted.
5. Went through Matt’s post: Right-click on the Windows Start logo > COMMAND PROMPT (ADMIN)
6. Entered this code where the cursor is flashing:  sfc /scannow (Came back with errors that could not be fixed.)
7. Entered Dism /Online /Cleanup-Image /RestoreHealth(Came back with Error code:  0x800f081f)
8. Downloaded the Tech Bench Upgrade Program using this link: http://www.microsoft.com/en-us/software-download/techbench
9. Deleted existing CBS Log file at: “C:\Windows\Logs\CBS\CBS.log”
10. Mounted the downloaded “Win10_1511_English_x64” by right-clicking and selected “Mount”. It came up as drive “E:\” in Windows Explorer.
11. Ran the DISM command in Command Prompt (Admin): DISM /Online /Cleanup-Image /RestoreHealth /source:WIM:E:\Sources\Install.wim:1 /LimitAccess

*IMPORTANT!: Make sure that the source is correct! For example, "/source:WIM:E:\Sources\Install.wim:1 /LimitAccess" in this case the source of the Mounted ISO is E:. Just check the file explorer after mounting the ISO. 12. Restarted. 13. Opened COMMAND PROMPT (ADMIN) again as above 14. Entered sfc /scannow (Found errors again but fixed.) 15. Entered Dism /Online /Cleanup-Image /RestoreHealth(Restored. No errors.) 16. Restarted. 17. Was getting poor battery life so I updated battery drivers per http://www.lovemysurface.net/how-to-update-surface-battery-drivers/ 18. Restarted. 19. Reset Edge browser due to unresponsiveness per http://answers.microsoft.com/en-us/windows/forum/windows\_10-networking/microsoft-edge-hanging-unresponsive-frequently/8f78c5cd-1b69-4cd5-84fd-3c5882b11da1 20. Instructions: RESETTING THE MICROSOFT EDGE WILL REMOVE YOUR BOOKMARKS AND HISTORY. Follow the instruction provided below and check. 21. Navigate to the following location: C:\Users%username%\AppData\Local\Packages\Microsoft.MicrosoftEdge_8wekyb3d8bbwe 22. Deleteeverything in this folder. (When deleting, I found that I couldn't delete everything so after deleting what I could, I restarted and entire folder disappeared.) 23. Now press Windows key and type Windows Powershell in search box. 24. Right click on Windows Powershell and select Run as administrator. 25. Copy and paste the following command.

Get-AppXPackage -AllUsers -Name Microsoft.MicrosoftEdge | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml" –Verbose}Disclaimer: The Reset Edge Settings feature might reset security settings or privacy settings that you added to the list of Trusted Sites. The Reset Edge Settings feature might also reset parental control settings. We recommend that you note these sites before you use the Reset Edge Settings feature. Resetting Edge isn't reversible, and all previous settings are lost after reset.

Also, if you have any third party security software installed in the computer, temporarily disable it and check again.

So far so good. I’ll keep you posted if I come across anything else.
