As you undoubtedly know, for now my recommendation about Windows 10 is: Stay put when you’re on 7, upgrade when you’re on 8/8.1. If you disagree, that’s fine: do what works for you. Of course, there is an “if”, namely, you’d better upgrade to 10 in order to secure the 10 upgrade for free before the promotion ends. As such, I’ve been a busy bee, taking Windows 7 machines, making an image of their disk, then upgrade and the revert to the 7 image.
Technically, you can upgrade to 10, ensure your machine is activated and then click the “revert to 7″ button in the “Upgrade” section somewhere. You have 30 days to do this. Now, personally, I prefer the “image-upgrade-restore” process because you do not know what Microsoft does when you click the rollback button. Is your machine hash flagged? Well, you get to say what you think of 10, but there is most likely not a human soul that will ever see these complaints.
Being more the Unix guy, I automated my work as far as possible. The automation consists of three parts: an imaging script and two windows scripts (reg and cmd). The first script is actually rather old and was originally written for other purposes: image newly bought PCs. It uses parted, so I assume that it should work on GPT partition layouts, but I have never tested this.
Now, to be entirely honest, you’re not going to manage to do the imagining without a little crash course on devices and the Linux command line. (Only tested on Ubuntu 14.04 LiveUSB. Dependencies are: ntfsclone, dd, dmidecode, hdparam and probably another few)
Basically, you’ll run it as following: sudo ./generate-image.sh /dev/sda
However, this assumes a few things: your working directory has my script, that in this working directory you have enough space to store the generated images and that the disk you want to image is /dev/sda (which it most likely will be, but I cannot say for sure). You also need to be sure that no partition of /dev/sda is not mounted. (Hey, now that’s something I could add to my script…)
When you run that script, it will create a directory based on your machines information, and will attempt to image the mbr (full and without partition table), and all partitions. For vfat it reverts to dd, for ntfs it reverts to ntfsclone and it generates a restore.sh script for your convenience for easy restoration. I’d say: cool, but you may think otherwise.
Nevertheless, I have decided to publish it here for the nerdier guys.
So, then you upgrade to 10, wait until it’s activated and that’s the last you’ll see from Windows 10.
Now, you boot back to your LiveUSB, go to the image directory the script created and run sudo ./restore and it will restore everything magically. If you want to use the backed up partition table, give any parameter (it’s a bit dumb, yes…).
When it’s all done… Reboot. You’re back to your Windows 7 machine as if nothing ever happened.
Now for the part any Windows user can do. The two scripts in the privacy.zip, are privacy.cmd and privacy.reg. The reg file you can just double-click, and it will essentially mark your machine as being “not interested in Windows 10, don’t bother me any more”. It disables GWX (the Windows 10 notification icon), disables the upgrade function, disables reservation and disables the fact that recommended updates are treated like important updates. This is important, because Microsoft used the “recommended” channels to push these -let’s just say “annoying”- patches to your computer.
The privacy.cmd script does something entirely different. If you haven’t been living under a rock the last months, you know that Microsoft pushed patches that adds a tracking services to your pristine Windows 7 installation. Now the script starts off with stopping that service, and then disabling it. I do this, because the uninstallation of the offending patches might fail for some reason. At least, then you’re sure the service is off. After it has done this, the script tries to uninstall the patches related to the Windows 10 upgrade and the tracking service.
Be advised, in order for the privacy.cmd script to work you need to run it as Administrator. Right click on it, then select “Run as Administrator”. It might take a while.
Congratulations, the nagging for the upgrade should stop, until Microsoft decides to push it as an important upgrade. After a reboot, you may want to manually mark these patches as hidden. Perhaps I should try to figure out, whether you can do that with a registry patch too.
