Vulnerabilities are flaws in the specific implementation of hardware, software, protocols, or system security policies, which allow attackers to access or damage the system without authorization. Specific examples include logic errors in Intel Pentium chips, programming errors in early versions of Sendmail, weaknesses in the authentication method in the NFS protocol, and improper configuration problems when Unix system administrators set up anonymous Ftp services. May be used by attackers to threaten system security. Therefore, these can be considered as security vulnerabilities in the system.

2. It can bring some better usage experience, but there will be some compatibility issues.

Because the new system hardware manufacturers have not had time to optimize and improve the system, it is recommended to wait for optimization and upgrade.

Compatibility (compatibility) refers to the degree of mutual coordination between hardware, software, or a combination of software and hardware systems. The concept of compatibility is relatively broad. Compared with hardware, several different computer components, such as CPU, motherboard, graphics card, etc., if they can cooperate with each other and work stably during work, it is said that the compatibility between them is better. , otherwise it means poor compatibility.

3. Use Optimization Master or Super Rabbit to clean the registry and junk files.

4. Close some startup programs. Start-Run-msconfig---Start. Except for anti-virus software and input methods, general programs can be closed.

5. Delete unused program software.

6. Defragment the disk--Start--All Programs--Accessories--System Tools--Disk Defragmenter--Select C--Analysis--Defragmentation.

7. Reduce the memory burden and do not open too many programs. If there are too many documents open or too many programs running at the same time, there will not be enough memory to run other programs, and unused programs and windows must be closed at any time.
