Explanation
If a software update causes performance issues, rolling back or uninstalling the update is the best initial troubleshooting step.
If a system experiences extreme slowness immediately after a software update, the most effective initial troubleshooting step is to uninstall the update. Updates can sometimes introduce bugs, incompatibilities, or system file corruption that negatively impact performance. Rolling back or uninstalling the problematic update can quickly restore system speed and stability, especially if the issue began directly after the update was applied. This approach is supported by Microsoft and IT troubleshooting best practices, which recommend reverting to a previous state when new updates cause problems.
If uninstalling the update resolves the issue, you can then monitor for new updates or patches from the software vendor. If the problem persists, further steps such as running system file checks (using sfc /scannow), cleaning up temporary files, updating drivers, or performing a malware scan may be warranted. However, starting with uninstalling the update is the most direct and effective first action for this scenario.
