We have slightly modified a tool from Rob C. Maehl (github.com/rcmaehl/WhyNotWin11, www.heise.de/download/product/WhyNotWin11) for two purposes:

• It checks whether the computer on which the tool is executed is sufficient to install Win11.
• In addition, data about the computer (CPU, memory, network information, ...) is sent to ICBM-IT - this can be viewed before sending; no directly personal data is included.

To begin, please download the executable programme under the link

WhyNotWin11-ICBM.exe

on your Windows computer.

To run the programme:

• Start the downloaded programme - please skip the warning regarding the missing certification.
• After a short time, the result of the Win11 check should be displayed.
• The programme can then be closed using the 'x' in the top right-hand corner. The data that will be transferred to us will then be displayed - please agree to this transfer. This data is also stored locally on the computer and can alternatively be sent by email.
• After agreeing, you will be asked for the room, enter this in the format W3 5-504. If the Windows computer is a notebook or e.g. is operated outside the university, please enter the university office room number.
• At the end, a window with "Result saved OK" should appear.

If errors occur, try also the 32-bit binary WhyNotWin11-ICBM-32.exe if there are also some errors please send a screenshot with the error message to so we can fix it.

Further information:

In addition to the Win11 compatibility check, we also use this opportunity to get an overview of the computers currently available at the Institute. We therefore ask you to carry out this test on all current Windows computers. This also makes it easier for us to respond to enquiries from the central IT department, e.g. about computers with IP N.N.N.N.N 
This also allows us to find out on which computers settings (computer name, domain affiliation, ...) need to be changed if possible.

The modified source code can be viewed by interested parties at gitlab.uni-oldenburg.de/sebo8575/whynotwin11-icbm

Central IT has also collected information on the update - however, this is only partially applicable to us. The information can be found on the IT services pages at Help for the changeover to Windows 11.
