This tutorial includes a list of the most common problems in Windows 10 and 11 and basic tips for fixing them. Almost all Windows problems can be fixed using its own tools: system utilities and troubleshooters, advanced startup, the Command Prompt, the Control Panel, and the latest device drivers. Are you experiencing any of the issues below? There's a solution for everyone.
1. Unresponsive apps
When a Windows application freezes, nothing moves on the screen, and even other programs become unresponsive. Applications often behave this way due to overheating in the case/bottom of the laptop and memory issues.
- To unfreeze stuck apps, open Task Manager using Ctrl + Alt + Del Or from the operating command Win + R followed by Taskmgr.
Right click to end those tasks in "Operations". If you are able to save your work, perform a clean reboot.

3. Blue Screen Errors
Blue screen errors don't have a simple explanation, but they are annoying. Also known as error checking or stop code errors, they display error lines related to third-party software, hardware, Microsoft code, or corrupted memory.
Each blue screen error has its own stop code that is displayed on the screen, such as: “0x000000xyz”. Can be viewed in Event Viewer , which opens from Win + R by typing eventvwr.exe Or eventvwr. msc.
After you see a blue screen, analyze the dump files generated by the crash using Debug with Windbg. The best way to fix these errors is to use the advanced Windows startup menu (also known as the boot menu). To start this, go to “Settings -> System -> Recovery -> Advanced startup -> Restart.”
Use one of these options in the Advanced Startup menu:
- Uninstall updates: The blue screen is usually caused by incompatible drivers or third-party software.
- system recovery: Restore the operating system to an earlier date and time when the problem did not exist.
- Startup Repair: Use it if you have a blue screen due to boot issues.
- Factory image restore: Restore the computer to the condition it was shipped in (for use only in extreme cases).
