sysprep – a fatal error occurred

I’m currently testing out Windows Deployment Services, and while working with sysprep on a Windows 7 Pro client machine, I got the following error:

Nothing seemed to work, till I tried the following recipe:

Open the run-menu, type in regedit and go to HKEY_LOCAL_MACHINE\SYSTEM\Setup\Status\SysprepStatus. Find GeneralizationState and set the value to 7.

Run a command prompt with administrative privileges. Type:

Open up regedit again and find HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\SoftwareProtectionPlatform. Find SkipRearm and set the value to 1.

Finally, in your current command prompt type:

Try running sysprep again now. Hopefully it should work. That’ll save you some time of frustration and hopefully you won’t go bald sooner.

Should this not work, check the sysprep-log file at C:\Windows\System32\Sysprep\Panther\setuperr.txt.

No Wi-Fi device found

I just reinstalled one of my machines with Fedora 21. The install went great, but when the machine was done rebooting, and I was trying to set up my access to a wireless network with nmcli (NetworkManager), I got the following error-message:


Spending a lot of time finding what the problem was, I finally found the solution.  It seems that Wi-Fi support in NetworkManager has been separated to a plugin. The package NetworkManager-wifi was missing. According to Pablo S. Torralba, who was kind enough to comment on this post, it should be enough to kill NetworkManager and launch it again as root. Should that fail, you can always try the old reboot-trick!  Either way, it should hopefully be working.
