Elementary exercise: Use the system cleaning function of Windows7 Optimizer to clean up infrequently used files.
After downloading and installing, open the Windows7 optimizer, do some preliminary system optimization first, then enter the system cleaning, then enter the system disk to slim down, first analyze the system disk content, and then click Delete directly. Some uncommon backup files were deleted.
2. Close the virtual memory.
Today's notebooks are standard with 2G or 4G memory. If you don't run large-scale software often, you can turn off virtual memory.
Methods: Right-click the desktop "PC" properties, enter the advanced system settings, then click the settings under the "Performance" menu of "Advanced" options to enter the performance options, and then click Advanced to enter the virtual memory settings options. Find the disk where the virtual memory is set, then click on the non-paging file below and confirm until you exit and restart, then you can delete the virtual memory. If you need to run some large-scale software, it is recommended to set the virtual memory smaller, preferably accounting for half of the physical memory!
3. Turn off system restore
Methods: Right-click to view the properties of the desktop computer, enter advanced system settings, then enter system protection, move the mouse to the drive letter of the configuration system disk, click Settings to enter system restore settings, and just turn off system protection directly!
4. Close the hibernation file.
Hibernation is to write all the data in the memory to the hard disk, then shut down the system, and then write the reserved data back to the memory at the next boot. Although these settings have certain benefits, they are not needed by ordinary users at all, so it is recommended to turn them off.
Methods: Start-All Programs-Accessories-Command Prompt, run as an administrator, and enter powercfg -h off.
Through the above four steps, the capacity of Windows7 system can be completely controlled within 5.5G, and the running speed of the system will be significantly faster. Of course, patients' friends can also delete some unnecessary system files to further reduce weight loss.
Unused software can also be uninstalled. There are so many system files and programs that many friends don't know how to uninstall them. By the way:
Ten services that can't be shut down under Windows7
1. antivirus software service (even trial version)
2.DNS client
Official explanation: DNS Client Service (dnscache) caches the name of Domain Name System (DNS) and registers the complete computer name of the computer. If the service is stopped, DNS name resolution will continue. However, the query results of DNS names will not be cached, and the computer name will not be registered.
If you stop this service, your computer will not be able to interpret DNS information and use domain names to log on to websites.
3. Network connection
Official explanation: Manage the objects in the "Network and Dial-up Connections" folder, where you can view local area networks and remote connections.
If this service is stopped, you will not be able to configure the network, create network links and surf the Internet.
4. Plug and Play
Official explanation: It enables computers to recognize and adapt to hardware changes with little or no user input. Stopping or disabling this service will cause system instability.
5. Print spooler system
Official explanation: Load the file into memory for later printing.
Without it, you can't treasure other people's cards. This is a printing service.
6. Remote procedure call
Official explanation: RPCSS service is the service control manager of COM and DCOM servers. It performs object activation requests of COM and DCOM servers, object exporter parsing and distributed garbage collection. If this service is stopped or disabled, programs using COM or DCOM will not work properly. It is strongly recommended that you let the RPCSS service run.
This is very important (that is, very important). If you ban him, your system won't start.
7. Workstation
Official explanation: Use SMB protocol to create and maintain the connection between client network and remote server. If this service is stopped, these connections will be unavailable. If this service is disabled, any services that explicitly depend on it will fail to start.
As the name implies, if you ban it, your computer will disappear into the intranet, not to mention playing Microsoft's network resources with medie.
8. Network Location Awareness (NLA)
Official explanation: Collect and store network configuration information, and notify the program when the information is modified. If this service is stopped, configuration information may not be available. If this service is disabled, all services that explicitly depend on it will fail to start.
This is a wireless network link, but banning it will cause many problems.
9.DHCP client
Official explanation: Register and update the IP address of this computer. If this service is stopped, computers will not be able to receive dynamic IP addresses and DNS updates. If this service is disabled, all services that explicitly depend on it will fail to start.
DHCP service is forbidden, you must set the IP manually.
10. Encryption service
Official explanation: it provides four kinds of management services: directory database service, which is used to confirm the signature of Windows files and allow the installation of new programs; Protected root service for adding and deleting certificates of trusted root certification authorities from this computer; Automatic root certificate update service, which is used to retrieve the root certificate from Windows Update and enable SSL. Key service to help register this computer to obtain a certificate. If this service is stopped, these management services will not work properly. If this service is disabled, any services that explicitly depend on it will fail to start.
Banning this encryption service will lead to the decline of computer security index, unable to automatically update and unable to use ssl.
