Hello to everyone,
I am writing from Estonia and I was using a 4 four years old Dell Optiplex 9020. My reconstructed machine (16 GB of memory) worked fine and I had no troubles with it at all. The problems started on Friday, 6. october 2023. This is a few days before the update (KB5031356) of 10. october 2023. At first I thought that it was some kind of cyberattack, because the complete update history of my Dell Optiplex was erased. I noticed at the same time, that something damaged or better told erased as well a lot of files associated with uninstallation of software, fore example everything from Wise (Wise Disk Cleaner, Wise PDF Reader, Wise Registry Cleaner etc). Some examples of the erased files are this: "unins000.msg" and "unins000.dat". A lot of software prior to the update stopped working, for example Dell Supportassist, Dell OS Recovery Plugin for Dell Update, Dell OS Recovery Tool etc. As well applications from Microsoft Store, for example Microsoft To Do, Dell Digital Delivery and as well the Microsoft Store app itself -- I had to reinstall it with the help of appxbundle. Other options failed. A lot of Dell software became completly useless. The Dell OS Recovery Tool isn t starting in Windows 10. I had serious trouble reinstalling Dell supportassist. With the stand of 17.10.2023 my Dell Optiplex has become completly useless after installing the update KB5031356. I must remark that the update loaded very badly and was stuck by 30% and loading it took several hours. After downloading the update things got worse. I have got at least 10 blue screens of death. The most common cause is a "Critical process died". I have no idea what this process should be. None of the recovery options works anymore. System Restore has become a complete failure -- "you must enable system protection on this drive", I did, and it dosen t worked at all. I tried a lot of the Command Prompt options with different commands nothing worked, beginning with sfc /scannow. It isn t possible to uninstall the latest updates as well, because there is nothing to choose from. Still got the same message "Critical process died". I have noticed that a lot of files are missing from the update, witch leads to system devices not recognized, for exaple Canon Powershot A620. The following files are missing from update KB5031356: "WpdUpFltr.sys" & "winusb.sys". Visual Studio 2022 got damaged as well prior to the update -- files are missing. Today I can t use anymore my computer and have nothing to work with anymore. I can bring my computer to repair, but I am out of options restoring the system. I have more than 10 restore points nothing helped. In the last days I have fasted a lot of my free time, to restore my computers funtionality with the result of a useless machine. Thanks Microsoft.
