If you use virtual machines or dual-boot with Linux/macOS:
Ensure "Set time automatically" and "Set time zone automatically" are ON (or off if you manage manually).
Open an elevated Command Prompt and run:
Verify BIOS/UEFI clock:
Check CMOS battery age (if machine >3–5 years, consider replacing).
Confirm Internet connectivity and that NTP servers are reachable (e.g., time.windows.com).
If running inside a VM, ensure host and guest clocks are synchronized and guest time sync tools are installed.
Check Windows Event Viewer (System) for Time-Service or kernel time drift warnings.
Inspect WinOLS logs (if available) or the exact error dialog for additional codes/messages.
Check certificate validity used by WinOLS: open the installer/executable properties → Digital Signatures / Details → View Certificate → Valid from/to.
If using an external license dongle, confirm its drivers are installed and updated.
A: Possibly, but it’s drastic. First, try Steps 1-5 above. A full OS reinstall will wipe the corrupt cache, but the error will return if the root cause (e.g., a bad BIOS battery) remains. winols+your+system+date+is+wrong
