After the last reinstallation of Windows (both at home and at work), I decided that from this day forth, I’d be working as unprivileged user (ie not as local administrator). Now, working as unprivileged user is some kind of relief (since not every program is able to wreak havoc within your computer), but also somewhat of a burden.
Up until now, I had serious troubles burning CDs and/or DVDs as unprivileged user. Basically InfraRecorder refused to work at all. Only way that I had left, was copying the ISO to my local disk and then use runas in conjunction with InfraRecorder, to execute as Administrator.
Execute secpol.msc as Administrator. You can configure this security setting by opening the appropriate policy and expanding the console tree as such: “Computer ConfigurationWindows SettingsSecurity SettingsLocal PoliciesSecurity Options“. Toggle “Devices: Restrict CD-ROM access to locally logged-on user only” to enabled. After logging of and logging back on, you should be allowed to use the CD-drive as unprivileged user.
