I came across an issue recently where the Outlook security dialog box popup was broken. Rather than looking as below, the username and password fields where missing:
The dialog box appeared as:
Notice that the username and password fields are missing! Also missing, and the key to this issue, is the picture is missing too. This is usually an empty box, but for some companies they use Group Policy to push out a different graphic.
That image is a bitmap stored in “C:\ProgramData\Microsoft\User Account Pictures”.
At a client of mine, the marketing department had requested the company logo replace the user picture and provided at 1MB file for this purpose. The file was deployed to all machines and overwrote the user.bmp by way of GPO preferences. Resizing user.bmp to under 48K in “C:\ProgramData\Microsoft\User Account Pictures\” on a single machine resolved the issue for users on that computer. We then changed the source of the image to under 48K centrally to fix all users.
Note that this was Windows 7 – different file sizes and dimensions exist for different versions of Windows. For example a user.bmp file on Windows 10 can be 448×448 and the default is just under 600KB. So again, the 1MB file mentioned above might also break Windows 10, but to fix the issue on that OS I probably dont need to reduce the file size so small.
Once you have installed Windows 7 RC and downloaded Microsoft Virtual PC you might have the need to run Microsoft Official Curriculum courseware virtual machines. And therein is a problem.
The virtual machines are built to use Virtual Server 2005, but that cannot install in Windows 7, so you cannot use the Lab Launcher. Though you can install the courseware drives, you will need to run the installer in compatibility mode or the VHD installer will not run.
Once you have the VHD files unzipped you need to configure Microsoft Virtual PC to load them up. This though is a problem if you are not located in the same timezone as the creators of the base disks (PST timezone).
The steps to create a virtual machine when you are in a different timezone are:
- Start the virtual machine wizard and make a note of the location value. You will need to modify files in this location later on
- Set memory and untick the network connections option
- Browse to the exiting hard disks folder. Enable undo disks at this time as well
- If you are in a different timezone you will get the following cryptic error
- Click OK and modify the file used to point to either any of the “allfiles” disks (as these are not differencing disks) or create your own empty vhd for the time being
- Complete the creation steps and then bring up the settings of the new virtual machine (with the wrong disk attached)
- Modify the network settings to Internal Network and add any additional disks needed (this will be described in the full setup guide for the course) and close the settings dialog.
- Browse to the folder that contains the actual settings file (the vmc file). This folder is the location value from step 1 (defaults to C:\Users\username\AppData\Local\Microsoft\Windows Virtual PC\Virtual Machines).
- Open the vmc file in Notepad (or an XML editor) and change the settings to that which you require. These changes are for disks. Look for ide_controller 0 and ide_controller 1 (if present) and change the name of the vhd file to the correct disk name.
- Modify the time sync. settings as per disabling-time-synchronization-under-virtual-pc-2007. The virtual machines from Microsoft for training purposes have a grace period and if you bring them up with the current date/time on them (which Virtual PC 2007 does automatically) then you will need to activate them.
- Save the file when your changes are completed.
- Start the virtual machine. You will see this error message – Inconsistency in virtual hard disk time stamp detected – The virtual hard disk’s parent appears to have been modified without using the differencing virtual hard disk. Modifying the parent virtual hard disk may result in data corruption. It is strongly recommended that you mark the parent virtual hard disk as read-only to prevent this in the future. If you recently changed timezones on your host operating system, you can safely continue using this virtual hard disk.
- This can occur for a number of reasons, but if the reason is timestamps then click OK. DO NOT click the option not to show the message again, or you will not be able to get past this error without modifying the options.xml file in C:\Users\username\AppData\Local\Microsoft\Windows Virtual PC.
The virtual PC will start, and will prompt you about updates to the integration components, but that is only a minor , so that can be ignored when you are presented with that error, unless you want the error to never show again per machine, in which case install (at your own risk and numerous reboots) the integration components.
Finally, you might need to reactivate some machines, as the hardware will have changed.
