Windows 11 Troubleshooting: Common Problems in 2026

Before you start exploring advanced fixes, it's important to identify the most frequent Windows 11 troubleshooting scenarios we see in our computer repair shop in West Palm Beach:

Diagnosing and Improving Windows 11 Performance

Step 1: Check for Resource-Hungry Programs

Open Windows Task Manager (Ctrl+Shift+Esc) and sort by CPU, memory, and disk usage. Close unused applications that consume excessive resources. If persistent, consider upgrading hardware or consulting a PC repair technician.

Step 2: Manage Startup Apps

Disable unnecessary startup programs via Task Manager → Startup to accelerate boot time. Fewer programs launching on startup means more resources for your daily work.

Step 3: Clean Up System Files

Use the built-in Disk Cleanup or Storage Sense utility (Settings → System → Storage) in Windows 11. Regularly remove junk and temporary files to prevent slowdowns.

Fixing Windows 11 Update & Upgrade Issues

Windows 11 updates keep your system secure, but failed installs or looping restarts frustrate many users. Here are practical troubleshooting tips:

Step 1: Run the Windows Update Troubleshooter

Navigate to Settings → System → Troubleshoot → Other troubleshooters → Windows Update. Let the tool diagnose and automatically fix common update problems. For detailed guidance, see the official Microsoft Support page.

Step 2: Clear the Windows Update Cache

If updates still fail, stop the Windows Update service and delete contents from C:\Windows\SoftwareDistribution. Restart your computer and try updating again.

Step 3: Ensure Device Drivers Are Up to Date

Outdated drivers may block updates. Use Device Manager to check for errors and install the latest drivers from Microsoft's device driver support.

Resolving Blue Screen Errors & Crashes in Windows 11

Blue screen errors (BSODs) can result from software conflicts, faulty drivers, or failing hardware. Steps to fix:

• Note the STOP code displayed on the blue screen—it offers clues for the root cause.
• Uninstall recent apps or updates if the issue started after installation.
• Update all device drivers, especially graphics and chipset drivers.
• Run built-in diagnostics: Go to Settings → System → Recovery → Advanced startup.
• Check hardware health. If you suspect a faulty RAM module or SSD, consult a professional repair technician.

Windows 11 Network & Wi-Fi Connectivity Troubleshooting

Wi-Fi and Ethernet issues remain common. Here’s how to troubleshoot network connectivity on Windows 11 devices:

Step 1: Use the Network Troubleshooter

Go to Settings → Network & Internet → Network troubleshooter and follow on-screen prompts.

Step 2: Reset Network Settings

Settings → Network & Internet → Advanced network settings → Network reset. Reconnect to Wi-Fi and test connectivity.

Step 3: Update or Roll Back Network Drivers

Device Manager → Network adapters—right-click your Wi-Fi/Ethernet adapter to update or roll back the driver.

Printer and Peripheral Issues with Windows 11

Printer not appearing, showing offline, or not printing at all? Try these steps:

• Disconnect then reconnect the printer’s USB cable or re-pair via Bluetooth/Wi-Fi.
• Remove and reinstall the printer from Settings → Bluetooth & devices → Printers & scanners.
• Download the latest manufacturer drivers from their official site.

Protecting Windows 11 Against Viruses and Malware

In 2026, malware threats are still a major risk. Symptoms include slowdowns, pop-ups, or unauthorized system changes. When in doubt:
