First, the relative optimization of boot acceleration.
The first thing you need is to start typing msconfig and enter directly.
Then find the startup in the pop-up window, and then you change back to see a lot under the startup bar. . .
Don't be like me. I started Project 98 because I really needed it. Because I have a bad memory, I won't open that software unless I turn it off!
Here are some important bird word explanations!
Intel (all names are Intel Universal User Interface) is a driver and software related to CIMS. Must be ticked! ! !
REALTEK High Definition Audio Manager is sound card driver software. Better tick! ! ! Maybe some of them didn't have this, so they changed to another sound card driver.
Lenovo Onekey Theater application is a one-click audio-visual tool. Everyone should know that it is best to tick! ! !
Lenovo Energy Management and Lenovo Battery Management manage Lenovo's power supply. For Lenovo, this is like a powerful software heart. If little y wants to die, he can collapse at once! Must be ticked! ! !
Synaptics pointing device driver is a touchpad driver. You'd better keep this Of course, if you have been using an external mouse, you don't need = =.
Bluetooth software is Bluetooth software. You don't want it, and you don't have to!
First of all, Windows comes with its own optimization scheme.
1: system configuration
Press and hold the Win logo key +R to start the operation, enter MSCONFIG, and then open the system configuration.
You can turn off some unnecessary startup items.
After testing, the startup item of Y470 can be completely disabled, except that the function key has no icon prompt, and everything is normal. Friends who pursue boot speed can completely disable it, and touch keys such as sound are still valid, but there is no desktop icon prompt.
2. Close the virtual memory (note: if the original memory is only 2G, please do not close it if the memory capacity is not upgraded to 4G, otherwise the system will easily explode with memory, leading to process and even system crash).
Right-click my computer, select Properties, then select Advanced System Settings on the left, click the first performance setting button under the Advanced menu, click Advanced in the performance option box, then click the change button of virtual memory below, finally select the partition where the system is located, then click to select the unpaged file below, click OK, and finally confirm to quit gradually. After restarting the system, you will find that the virtual memory is gone, and the C drive has lost 3~4G.
3. Turn off the system hibernation (Note: If you often covet children's shoes with hibernation function, please don't do this step, otherwise the hibernation function will not be available).
Open the directory C:\Windows\System32, find cmd.exe, right-click to run as an administrator, type powercfg -h off, and press enter. You can also use Windows7 Optimizer.
3. Turn off the system restore and delete the restore point (don't turn off the children's shoes that are used to system restore).
Turn on my computer and get familiar with the advanced system settings. Select the system protection menu, select drive C (the system disk is turned on by default), click Configure, turn off the system restore and clear the restore point.
4. Delete components and backup files that Windows doesn't need.
Let's take a closer look at the location and content of these components that can be deleted:
1, C:\ Windows \ software distribution
Deleting this folder can free up 200M or more hard disk space, depending on the number of patches played by the system.
Under the normal operation of Windows, some files in this folder are used and cannot be deleted. If you need to delete it completely, you can press F8 to enter safe mode to delete it.
2、C:\Windows\winsxs\Backup
Deleting files under C:\Windows\winsxs\Backup is complicated. If you want to simply delete them, you can use the system cleaner included with Windows7 optimizer to delete them. Manual deletion requires first obtaining ownership of the backup folder.
3、C:\ Windows \ System32 \ DriverStore \ file repository
Many hardware supported by Windows and some original drivers of hot-swappable hardware are also stored here. Some children's shoes have been cleaned by the Windows7 optimizer, but the handles and cards that could have been hot-swapped did not respond after being plugged into the machine, because the files inside were cleaned. Therefore, if you need to clean up these children's shoes with redundant files, you'd better first install all the hardware to be used on the machine and install the driver, and then move the knife on this folder.
4. Other cleanable folders and temporary system folders:
C:\Users\Public\Music: Store sample music, that is, songs that can be heard by opening the media player after Windows is newly installed. I guess no one will listen ~ you can delete it with confidence ~
C:\Users\Public\Pictures: store sample pictures. I guess no one will read it ~ delete it ~
C:\Users\Public\Videos: Store the sample video, that is, the two paragraphs that can be watched by opening Media Player after the new installation of Windows ~ Delete it ~
The following folders are used to store temporary system files. Children's shoes can clean up garbage files as appropriate.
C:\Windows\Temp: Store the temporary files generated by the installation and operation of the program, which can safely delete the garbage inside.
C:\Users\ (current system user name) \AppData\Local\Temp: It is also used to store temporary files generated by program installation and operation, and the default temporary directory for WinRAR decompression is also here. You can safely delete the garbage inside.
C:\Users\ (current system user name) \ appdata \ local \ Microsoft \ Windows \ Temporary Internet files: All kinds of pictures, Flash and other contents downloaded by IE or IE kernel browser when browsing the web are stored here. When viewing the webpage, the contents inside will become junk files ~ Don't worry about cleaning up ~
C:\Users\ (current system user name) \ appdata \ local \ Microsoft \ Windows \ history: As the name implies, it stores Cookies, history, forms and passwords left by browsing the web. To clean up the saved passwords, browse the history and records, and delete the contents ~ in fact, it is cleared in IE- Internet option.
4, system service optimization:
It is strongly recommended to shut down system services:
1, super extraction
2. Program Ability Assistant Service
3, should be hardware detection
4、Windows Defender
5. Windows search
6. Security Center
7. Windows time
8. Windows backup
Services that can be shut down (can be shut down or not):
1, internet connection sharing (ICS)
2. IPsec policy proxy
3. Media Center Extender Service
4. net. Tcp port sharing service
5. Remote Desktop Configuration
6. Remote Desktop Service
7. Remote registration
8. Routing and Remote Access
9, the second login
10, SSDP discovery
1 1, system event notification service
12, Windows Image Acquisition (WIA)
4. Other optimization:
1, which greatly improves the interface reaction speed.
On the computer, right-click Properties:
2. close UAC.
Open the control panel-> System and security->; Change the user account control settings, pull the slider to the lowest position, and then press OK.
====================================================================================================
Second, the third-party software optimization scheme
1, Windows7 optimized host.
The most powerful Win7 system is specialized in optimizing software, which has the most comprehensive support for Win7 and friendly interface. In addition to system settings, it also has various optimization and cleaning functions. Highly recommended.
2. Super Rabbit
The old Windows system optimization software supports a full range of Windows systems. This function is in line with the Windows7 Optimizer. It is also highly recommended.
3. Master of 3.Windows Optimization
Like Rabbit, it is an old-fashioned optimization software, and it also supports all-round Windows systems. The powerful uninstall function of the software is especially powerful. It just needs to be cracked after being converted into charging software.
4、360
Needless to say, this software. Now Qihoo is making 360 bigger and bigger, but it is becoming more and more rogue. "One-click optimization" has always killed the startup item of Y460 shortcut key by mistake.
5. Cleaner
Powerful system cleaning software with simple interface.
6. Drive the cleaner 3
The old driver cleaning software supports many common driver uninstallations. The old driver couldn't be unloaded in the control panel, so it was cleaned up.
7. Driver's wiper
Like the drive cleaner 3, it is also a powerful drive unloading tool.
