    Hello Paul E. Humphrey,

    Just following on your case, if Solidworks 2025 continues to crash or experience File Explorer PDM vault latency following a recent Windows Quality Update, this represents a confirmed application-layer incompatibility between Dassault Systèmes' codebase and the updated Microsoft shell or .NET Framework 4.8.x servicing binaries. You must investigate the Windows Application Event Log specifically for Event ID 1000 (Application Error) and Event ID 1026 (.NET Runtime) to isolate the exact faulting module. If the crash originates from core Windows modules like ntdll.dll or clr.dll strictly post-update, this is a compatibility break that Microsoft will not issue an out-of-band hotfix for. According to Microsoft developer compatibility guidelines, Independent Software Vendors are entirely responsible for patching their software to comply with OS-level shell and security modifications. Your immediate, officially supported action is to pause Quality Updates via local Group Policy at Computer Configuration > Administrative Templates > Windows Components > Windows Update > Manage updates offered from Windows Update > Select when Quality Updates are received. Configure this policy to defer updates for the maximum 35-day window. This action reliably stabilizes your engineering environment on the last known good configuration and provides Dassault Systèmes the necessary lead time to release a certified Solidworks Service Pack hotfix.

    Hope this answer brought you some useful information. If it has, please consider accepting the answer so that other people sharing the same issue would benefit too. Thank you :)

    Hello Paul E. Humphrey,

    Your current description lacks the diagnostic data required to provide a definitive resolution. To formulate the exact fix, you should specify the exact Knowledge Base (KB) update number that triggered the failure, your current OS build, and the specific application behavior. You are experiencing Event Viewer exception codes such as 0xc0000005 pointing to sldworks.exe or ucrtbase.dll, Explorer.exe hangs when right-clicking files, or graphics driver timeouts (TDR). If the software crashes immediately upon opening assemblies, open the Device Manager and verify if your workstation GPU driver was recently updated by Windows. If it was, you must roll back to the specific Dassault Systèmes certified driver for your hardware and permanently block driver updates via the registry by setting the ExcludeWUDriversInQualityUpdate DWORD to 1 under HKLM\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate.

    If your issue is strictly related to File Explorer freezing or UI latency when interacting with the PDM vault after a cumulative update, this represents a known architectural conflict between the updated Windows shell and legacy context menu handlers. Microsoft frequently updates shell security, which requires Independent Software Vendors to patch their respective shell extensions. Because this is an application-layer compatibility issue, you must wait for Dassault Systèmes to release an official Service Pack hotfix. Until that patch is available, the strict Microsoft best practice is to temporarily remove the problematic update using an elevated command prompt with the syntax wusa /uninstall /kb:XXXXXXX. Following the rollback, deploy the TargetReleaseVersion and TargetReleaseVersionInfo Group Policy settings to lock your environment to the previous stable Windows build, ensuring your engineering workstations remain operational without compromising the integrity of the .NET component store.

    Hope you found something useful in the answer. If it helped you get more insight into the issue, please consider accepting it. Thank you and have a nice day!
