Windows 10 on Mac Bootcamp – fixes (Updated)

Update 19th August 2015: Apple have released Bootcamp 6, which fixes all of the below when using Windows 10. If you already have Bootcamp 5 installed, run the Apple Software Update utility to get the latest set of drivers. The only oddity I’ve had with Bootcamp 6 is that is resets your DPI scaling to 200%.

Windows 10 on Bootcamp (Macbook Pro 13 inch, Bootcamp 5.1) has some teething issues as of build 10162.

SSD Powering down problems

You might notice Windows hanging for extended periods of time or blue screening – the SSD is literally powering down underneath Windows. The Bootcamp drivers don’t properly support Windows 10’s powering down of the SSD to save battery. Your Event log might have references to “”Event 129, storahci – Reset to device, \Device\RaidPort0, was issued.” To fix this, you need to disable AHCI Link Power Management and prevent storahci from going into low power mode.

1. Copy and paste the following into a new text file called “enable-hipm.reg” and save it:

Windows Registry Editor Version 5.00



2. Double click the file to import the records into the registry.

3. Right click on the Battery icon in the Taskbar, select “Power Options”. Click “Change plan settings” under the “Balanced” option. Then click “Change advanced power settings”.

4. Expand the “Hard disk” node and you’ll see “ACHI Link Power Management – HIPM/DIPM”. You need to set the value to “Active” as seen below:


5. Create a another regedit file “storahci.reg” with the following content:

Windows Registry Editor Version 5.00


6. Double click the file to import the registry entries. This stops storahci from going into Low Power Mode.

A restart should then solve the SSD freezing problems.

System Restore, Restore Points and Windows 7 style backups do not work

Again, if you are getting messages such as “check the event log for VSS errors” when trying to backup or create a restore point, and then finding event log messages like:

Volume Shadow Copy Service error: Unexpected error CreateFileW(\\?\GLOBALROOT\Device\HarddiskVolumeShadowCopy48\,0x80000000,0x00000003,…).  hr = 0x80070001, Incorrect function.

Processing PreFinalCommitSnapshots

Execution Context: System Provider

Then you’ll find that this is another Bootcamp driver problem, specifically the applehfs.sys driver that allows read only access to HFS volumes. You need to disable this from starting up:

1. Download Sysinternals Autoruns and run it as an Administrator.

2. Search for “apple” and you’ll see “applehfs.sys”.


3. Disable it by unchecking AppleHFS and restart. You should now be able to create System Restore images and Windows 7 style backups.

Hopefully Apple updates Bootcamp for Windows 10. If I find any other issues I’ll update this post.

Windows 8.1’s user-hostile backup story

Update 13th June 2015: It looks like Microsoft has reversed course and reinstated the Windows 7 Backup and Restore feature in Windows 10! Success!

Update 16th Sept 2013: What follows is a rant written after upgrading to 8.1 and seeing my automated backups just stop working and the backup restoration function also removed. An afternoon was wasted faffing about with the new File History feature which still refuses to backup files not on my system drive and deliberately ignores files in the SkyDrive folder, preventing you from having a local backup. I now use CrashPlan which behaves like Windows 7 and 8.0 used to be able to back up files.

Windows 8.1 is now released to manufacturing and those with MSDN or Technet Subs can download it now.

I have the RTM version now set up on home and work machines and have been running the Preview versions on both my Surface RT and Surface Pro. Windows 8.1 has some glaring errors.

SkyDrive integration now built in, removes features compared to the old Desktop client

You no longer have to install the SkyDrive app separately as it is now built into the OS. Windows 8.1 makes a concerted effort to force you to use SkyDrive.


The above is a screenshot of a screen displayed during the upgrade process. Can you see the error?

“automatically backed up to the cloud”

This is nonsense – if you delete a file from your local machine, it will be deleted from the cloud. This is NOT a backup. Live mirroring is NOT a backup. If a sync goes wrong – your file disappears completely. There is no backup.

Edit: Turns out SkyDrive has a “Recycle Bin” for deleted files, but it removes files once it is full or after 30 days. So, you might randomly be able to get your file back. Version History also only works for Office documents.


On the left is Windows 8’s SkyDrive integration after installing the SkyDrive Desktop app. On the right is Windows 8.1’s built-in SkyDrive integration. This is now a system-level folder and doesn’t even have the syncing icons available. This folder is now virtualized and you aren’t guaranteed that the actual file will be present. Opening the file will sometimes download it from SkyDrive.

The “Windows 7 File Recovery” backup system has been removed in 8.1

Windows 8.0 actually contained two backup systems, the new “File History” and the awesome old backup system from Windows 7, threateningly renamed “Windows 7 File Recovery” as a warning that this will be removed. Lets compare the systems:

Windows 8 File History Windows 7 File Recovery
Files in Libraries and desktop only All files in all locations supported
No system image support Full system image support
No progress bar Progress bar

File History is Microsoft’s attempt to copy OS X’s Time Machine, except Time Machine actually backs up all your files and lets your restore the entire OS partition, just like Windows 7 did! At least you had the choice in 8.0 to use the old system. In 8.1, Windows 7 File Recovery has been removed completely, you can’t even restore your old backups!

Edit: You can create a System Image in 8.1 (Click “System Image Backup” on the File History screen) but this doesn’t work on an automated schedule, so is not an automatic backup.

It gets worse. File History is even more useless in 8.1.

“File History” no longer backs up your SkyDrive folder in 8.1

Microsoft really don’t want you to have a local backup of your SkyDrive files. Take a look at this:


Above: Windows 8 File History


Above: Windows 8.1 File History

No problem you think? Just add your SkyDrive folder to a Library and it should back up? Nope – all the SkyDrive files are ignored completely, even if you manually add them to a Library.

The response from Microsoft on this is beyond tragic (from here):


Your files “are protected by the cloud in case user lose/damage their device”. What about protection from user error or viruses or badly written programs? If your files get corrupted the corrupted files will sync to the cloud and then sync to all your other devices.


It appears that Microsoft are desperate to push SkyDrive, even at the expense of the computing safety of their customers – customers you’d hope were being educated about safe computing. Now I am on 8.1 I am personally stuck with no built-in backup system. My experience with File History has been awful – it appears to even ignore an additional Library I’ve created to include non-library files. I literally cannot get it to back up files on my computer, it is useless. I am going to have to go with a third-party backup system like CrashPlan now.

Windows 8.1 was Microsoft’s chance to undo the wrongs of Windows 8. Users are now faced with the prospect of upgrading and being faced with no backup solution, or even worse their existing backups just stopping working with no warning.

Sort it out Microsoft.

Edit: Some excellent discussion on this over at Hacker News:

Why I won’t be returning my Microsoft Surface RT

I’ve picked up a Microsoft Surface RT from the “temporary” New York Times Square Microsoft Store. While the purchasing experience was a bit of a mess (untrained sales staff – I ended up having to type my own details into their POS terminal as I’m not quite sure the guy knew how to type), I managed to make off with a properly boxed (I skipped getting the staff to unbox it and walk me through the “Out of Box Experience”) 32GB Surface, Type Cover and VGA adapter.

The device

This is an amazing piece of hardware. I’ve dabbled in and out of portable computing ever since the original Windows Tablets in the form of the HP TC1100. The TC1100 was ahead of its time – a full version of Windows in a tablet with a decent attached keyboard that went together to make a case. However, the hardware was pretty bulky – fans and a display too far away from the glass, making touch, even with the included stylus, inaccurate.

This really looks like something out of a Bond film. The tapered edges and kickstand both apparently go off at 22 degrees (I haven’t measured), looking deliberate – as if designed by actual designers. I would not be surprised if some ex-Apple guys worked on this device. The battery is said to go 10 hours of mp4 video – more than enough for a long haul flight, and I can personally attest to the quick charging of the Surface up to around 50% in about an hour. The camera is at an angle to compensate for the slant when using the kickstand. Portrait mode looks slightly ridiculous, but I can’t imagine using it in portrait when just sitting the device landscape in your lap works so well.

The Type Cover is like nothing you’ve seen before – forget the comedy Bluetooth “keyboard covers” for iPad users desperate to do a bit of actual work on their devices – this is genuinely a pleasure to use. The small multitouch trackpad is great, but strangely defaults to inverted scrolling like OS X Mountain Lion. My only gripe is that they still have the Caps Lock key – I will have to delve into the Registry to switch this to a Control key. Yes, I did say Registry…

The software

Windows RT is installed by default and is the most fascinating part of the device. Many pundits have long called for Microsoft to abandon backwards compatibility and build a new operating system – if they did, it would look something like this. Windows RT is Windows 8, but without the backwards compatibility legacy. The full Windows desktop is here – the Command Line, PowerShell, Windows Explorer, Paint, Notepad, VPN connections, BitLocker – the works. The only difference is that WinRT only allows Microsoft-signed applications to run on the desktop. Visual Studio 2012 can build ARM applications but this is blocked by Microsoft – bypass the block with a registry setting and the compiled binaries are blocked by Windows RT. I suspect this is because the device is subsidized and they hope to recoup revenue from the Windows Store apps, but it might just be a ploy to force developers to build Metro-style applications. The thicker, heavier, noisier Surface Pro is due soon and will run the full x86 Windows 8 Pro, bringing legacy support with it.

If the Surface RT is meant to be used as a main or only machine, this is going to cause problems. In the Microsoft Store, non-technical members of the general public were already asking if they “could use their iPhone with it” – yes, they can, but only to charge and download photos. iTunes will not install. Firefox will not install. Even some Windows Store Metro apps will not work – notably Google’s suite. If you or your company uses Google Apps, steer clear from Windows RT until Microsoft or Google budge and allow Google Drive syncing. There could be serious backlash due to Windows RT – if enough customers kick off a storm, Microsoft might remove the signature check when running ARM binaries, allowing third-parties to treat Windows RT like a first class citizen.

In reality though, a Surface RT is not going to be your only machine. It absolutely shines as a Remote Desktop thin client – you can have Visual Studio running on your 12-core beast machine in the office and just remote in to use it. Flash is built into the browser, allowing stuff like Adobe Connect to work without a problem – the web browser version being much better than the iOS version, which still hasn’t been updated to support retina or iPhone 5 long displays. One thing you can’t do is share your screen with Adobe Connect. Full desktop-class Web Apps such as Google Docs work fine in Metro IE10 and without any browser chrome, could be mistaken for a “native” application.

Games from the Windows Store run quite badly on Surface. Jetpack Joyride has a pretty bad frame rate when lots of sprites are on the screen. Hopefully there is room for improvement in drivers, but don’t expect iPad 4 quality graphics. You cannot see pixels when sitting back and typing thanks to ClearType, but the resolution is nowhere near the iPad Retina display.

You might have a few favorite Windows applications that won’t run on Windows RT. I was worried that I would not be able to live without Windows Live Writer, but it turns out that Word has had a great blogging tool since version 2007, and it is even better with 2013.

Office 2013 RT

The first thing you should do with Surface is run Windows Update. This updates the Preview version of Office RT to the final version. Microsoft plan to deliver incremental functional updates, giving another reason to get a Microsoft Surface and not another Windows RT ARM device. Other manufacturers could cause delays to updates like Windows Phone 7 has been plagued with – carriers and device makers literally stopping you from using the latest version of the software running on your device (if MS do a Windows Phone 8, you should get it instead of any third party offering).

Office 2013 starts up very quickly. Saving to SkyDrive or the local drives just works. This really has full compatibility with Office files. The only glaring omission is Outlook – however, Exchange accounts are fully supported in the Mail application and Gmail works great in IE10.

Why I’m keeping it

I can actually do something productive with this device, unlike the iPad which has been reduced to a wife-pleasing YouTube machine. It has a great built in RDP client for when you need to use software that does not run on WinRT. It has a USB port which works with actual mice, USB drives and even my Kensington PowerPoint remote. If the space runs out, I can just insert a Micro SD card and expand the storage capacity. The Surface fills a useful void between an iPad and a MacBook Air – something that you can just throw in your bag without a laptop bag cover but can still get some work done on. Word, PowerPoint and Excel come free with Surface RT – these separately would be $30 or so on an iPad as iWork but here you get the real deal. I really am sick of lugging around proper laptops when I could just remote into a beefy machine under my desk. With LTE tethering in Japan, this is becoming a reality.

Only buy a Surface RT if you know what you are buying and can live without full legacy application support. As a thin client for real world web applications, it might make some people very happy indeed.
