Why is my Styku system running slowly, freezing, or timing out during scans?

Why is my Styku system running slowly, freezing, or timing out during scans?

Slowness, freezing, or scan timeouts are typically caused by one of four things: low disk space, high RAM/CPU usage from competing apps, a weak internet connection, or a pending software update. Work through the self-serve checks below before contacting support — most performance issues can be resolved in a few minutes without a remote session.

What "slow performance" can look like

  • The software feels sluggish or unresponsive when navigating menus
  • The scan completes but the loading screen stays up for 10–20+ minutes before showing results
  • The software freezes or crashes partway through a session
  • Scans time out before finishing, requiring you to restart

Self-Serve Diagnostic Steps

Try these in order. After each step, attempt a scan to see if the issue is resolved.

Step 1 — Check Available Disk Space

Styku Studio and scan data require adequate free disk space to process and save scans. Low disk space is a common cause of freezes and timeouts.

  1. Open File Explorer and click This PC in the left sidebar.
  2. Under Devices and drives, look at the bar under your main drive (usually labeled C:).
  3. If the bar is red or the free space shown is less than 10 GB, the drive is critically low.

To free disk space quickly:

  1. Press the Windows Start button, type Disk Cleanup, and open it.
  2. Select your C: drive and click OK.
  3. Check the boxes next to Temporary files, Recycle Bin, and Thumbnails, then click OK → Delete Files.

If your drive consistently fills up, the Styku laptop may have more scan data stored locally than expected. Contact support to discuss data management options.

Step 2 — Check RAM and CPU Usage

High background CPU or memory usage reduces the resources available to Styku Studio during scans.

  1. Right-click the Windows taskbar (the bar at the bottom of the screen) and select Task Manager.
  2. Click the Performance tab.
  3. Look at CPU and Memory usage while the Styku app is open but idle (before starting a scan).
    • CPU consistently above 80% at idle = a background process is consuming too many resources
    • Memory used above 85% of total RAM at idle = not enough RAM for Styku to run cleanly

To close competing background processes:

  1. In Task Manager, click the Processes tab.
  2. Look for any non-Styku programs using high CPU or memory (e.g., antivirus scans, Windows Update in progress, Chrome with many tabs open).
  3. Right-click the high-usage process and select End Task — only do this for programs you recognize and opened intentionally.
  4. Avoid using other programs on the Styku laptop while scanning sessions are in progress.

If Windows Update is running in the background, wait for it to complete (or schedule it for off-hours) and restart the laptop before attempting scans.

Step 3 — Check Your Internet Connection

Styku requires a stable internet connection to sync scan data, validate the license, and process cloud-dependent operations. A weak or dropped connection causes timeouts and long loading screens.

  1. Press the Wi-Fi icon in the bottom-right corner of the Windows taskbar.
  2. Confirm the laptop is connected to a network and shows "Connected, secured."
  3. Open a browser and navigate to www.styku.com to confirm internet access is working.

If the connection is slow or dropping:

  • Move the laptop closer to the Wi-Fi router, or use a wired (Ethernet) connection if available.
  • Restart the router if other devices on the same network are also experiencing slowness.
  • If you are traveling or away from your normal location, hotspot your phone to provide internet access for the laptop.

See [How can I check the WiFi status on my Styku laptop and connect to a WiFi network?] for detailed reconnection steps.

Step 4 — Restart the Laptop

Fully shut down and restart the Styku laptop (Start → Shut Down — not Sleep or Restart from within an app). This clears temporary files and applies any pending Windows or Styku updates that require a reboot.

  • Do not run Styku on battery power alone. Keep the laptop plugged in at all times.
  • After restart, open Styku Studio and attempt a scan before opening any other programs.

Step 5 — Check for Pending Styku Updates

An outdated version of Styku Studio can cause instability. If an update is available, it will appear as a notification within the app. Install it and restart before scanning.

Do not change any settings inside Styku Studio — especially anything labeled Advanced or Debug. These are internal settings that can disrupt scan performance if modified.

If the Issue Persists — Schedule a Remote Session

If the steps above do not resolve the problem, contact Styku Support to schedule a live remote session. During the session, a support agent will:

  1. Connect to your Styku laptop remotely
  2. Review system performance and resource usage
  3. Check your internet connection and sync status
  4. Verify your Styku Studio version and install any pending updates
  5. Inspect software settings for anything that may have been changed
  6. Run a test scan together to confirm the issue is resolved

How to schedule:

  1. Log in to the Styku Business Portal at https://www.styku.com/portal
  2. Navigate to the Support section and submit a ticket
  3. Include a description of when the slowdown occurs, how long the loading screen stays up, and any error messages
  4. A support agent will respond within 1 business day and provide scheduling options

If Your Software Needs to Be Reinstalled

If a crash or software corruption is contributing to performance issues:

  1. Download and reinstall the Styku software.
  2. You may need your license key reset. Contact Styku Support through the business portal at https://www.styku.com/portal to have your license reset.
  3. Once you have this information, open Styku Studio and enter your account email, password, and license key. No data will be lost, as scans are stored on Styku's servers.

If this resolves your issue, no further action is needed.

If the problem persists, contact support and include: a description of when the slowdown occurs (every scan or intermittently), approximately how long the loading screen stays up before timing out, any error messages displayed, and whether the issue started after a specific event such as a software update, Windows update, or settings change.
