Adjust the router position to avoid interference, consider using an expander or Mesh system; 4. Check whether there are speed limits or data limit problems in the ISP, and upgrade packages or troubleshoot local faults if necessary.

Can I uninstall Microsoft Edge

Microsoft Edge can be uninstalled, but because it is a Windows system component, it cannot be uninstalled directly through the control panel like ordinary software. 1. Use a command prompt (administrator permissions) to uninstall the Edge installation package; 2. You can disable or replace Edge with the help of third-party tools; 3. Enterprise users can manage through Group Policy. Even if uninstalled, it may still be redeployed when the system is updated. Alternatives include: setting other browsers as default, manually removing the Edge icon, and hiding Edge using scripts. Users suitable for uninstallation include system geeks, enterprise unified management needs, and low-end device users who want to release resources. Ordinary users only need to change the default browser to avoid interference.

What is a portable version of a software

Portable software refers to a program that can be run directly from a USB flash drive and other mobile storage devices without installation. Its core feature is that it runs independently. All files are concentrated in one folder. The system registry is not modified. The configuration information is also stored in its own directory. The file is started by double-clicking. The advantages of using portable software include privacy protection, no administrator rights required, portability and no uninstallation. Common examples are FirefoxPortable, Notepad, and LibreOfficePortable. The identification method includes checking whether the download name contains the word "portable", whether it is in the ZIP compressed package format, and whether it comes from trusted platforms such as PortableApps.com. It should be noted that

Is it safe to disable Windows services to improve performance

Yes, disabling certain Windows services can improve performance while ensuring that service features are understood, but critical system services need to be avoided. 1. Services that can be safely disabled include non-essential services such as Fax, PrintSpooler (if not printed), BluetoothSupport, etc.; 2. Performance improvement is usually small, mainly saving idle resources, and disabling frequently-running services may be more effective; 3. The safe disable step is to view service details through services.msc, set the startup type to disabled or manual, and create a restore point to prevent errors. Be sure to operate with caution to avoid system problems.

How to fix weak wifi signal

Weak Wi-Fi signal at home can be solved by adjusting the router location, changing channels, installing expansion equipment and regular maintenance. 1. The router should be placed in the center of the home to avoid corners or close to electrical appliances, about one meter away from the ground and the antenna is perpendicular; 2. Use Wi-Fi analysis tools to switch to the idle channel, give priority to the 5GHz frequency band and enable the dual-band integration function; 3. If the area is large or the structure is complex, you can choose a Wi-Fi extender, Mesh networking system or power cat adapter; 4. Restart the router regularly and update the firmware to optimize performance and security.

Can my wifi provider see my browsing history

Yes, WiFi providers can see some of your browsing information. Specifically: 1. The WiFi provider can see the domain name, Internet time period, device type and traffic size of the website you are visiting, but cannot view the specific content of the HTTPS website; 2. The home WiFi administrator can also view the connection records and some traffic content through the router background or parent control software; 3. Methods to protect privacy include using HTTPS websites, connecting to VPNs, enabling browser privacy mode, and avoiding sensitive operations on public WiFi; 4. The company or school network is usually more stringent, and may record logs, install a proxy server, or even force decrypt HTTPS traffic, so you should try to comply with regulations and avoid visiting irrelevant websites.
