Windows Update - Deleting *.SPA & *.SYN files RRS feed

  • Question

  •  

    The problem results from a recent Microsoft Windows update.

     

    The cause is believed to be as follows:

    1)      The user downloads and installs an update to Windows XP

    2)      The system asks the user to perform a reboot, but the user decides to reboot later

     

    (The application in question "Q-Nest" is associated with CNC and CAM machining processes).

     

    Data submitted to Q-Nest between the windows download/install and the re-boot are corrupted. The system works correctly again after the re-boot, however customer’s have lost a full day’s work because of this problem.

     

    The files in question have the extension *.SPA (geometry) file, and an *.SYN (machining instructions) file. The problems arose following Windows updates on the 6th October in Denmark and 23rd October in Romania, is the *.SYN files are deleted between the Microsoft download/install and the reboot.

     

    If anyone can offer a reason for these files being deleted, I would be most grateful.

  • I am not so familar with the Q-NEST application, do you have a link to this?

    Can you look at your Windows Update History and tell me the names of the updates that were installed on the dates you mentioned?
