Computer comparison card (memory too small)

I found some suggestions from the Internet and thought it was okay to completely optimize your computer after anti-virus attack. I first optimized your computer with the optimization master or super rabbit, and then chose the following methods for optimization.
1. system property settings
1. Change the default value of BIOS to the optimized value, and set the boot sequence to the first boot.
2. disable idle ide Channels
Right-click my computer-properties-hardware-Device Manager ", expand "Ide ATA/PATA controller" and Right-click "Main" and "secondary" Ide Channel -- "Advanced Settings" -- set "device type" to "NONE ", set transfer mode to DMA (if available ".
3. Optimize Visual Effects
Right-click "my computer"-"properties"-"advanced", and click "Settings"-"Visual Effects" in the "performance" column to adjust it to the best performance, or remove unnecessary features.
4. Optimized Performance
Right-click "my computer"-"properties"-"advanced", and in the "performance" column, click "set"-"advanced"-select "program" for "processor plan" and "memory usage ".
Click "change" in the "virtual memory" area, select the system drive letter in the drive list, and set the Custom Size in "initial size" and "maximum value, click "set" and then click "OK" to exit. The Virtual Memory minimum physical memory is 1.5-2 times, and the maximum value is 2-3 times of physical memory.
5. startup and fault recovery
"My Computer" -- "properties" -- "advanced" -- "Startup and troubleshooting" -- "Settings", in the "system failure area, remove the "Write events to system logs", "Send management alarms", and "auto restart" check box. Set "Write debugging information" to "NONE "; click "edit". The notepad file is displayed:
[Operating systems] timeout = 30: Change 30 seconds to 0 seconds.
6. Disable Error Reporting
"My Computer" -- "properties" -- "advanced" -- click "Error Report", select "Disable Error Report", select "but notify me when a serious error occurs"-OK.
7. Disable system restoration.
Choose Start> my computer> Properties> System Restore to ensure system performance and security, we recommend that you disable the system restoration function for a partition disk other than the XP system disk. Click "set" to set "disk space to be used" to a minimum.
8. Disable Automatic Updates.
Click "start", right-click "my computer", "properties", "Auto Update", select "Disable auto update", or select "notify me when available download ......".
9. Disable Remote Desktop
Start -- Right-click "my computer" -- "properties" -- "remote ", remove the "Remote Assistance" and "Allow Remote Assistance invitations from this computer" in the "Remote Desktop" and the "allow users to remotely connect to this computer" check-OK.
10. Disable the sleep function
Click Start> Control Panel> Power Management> sleep to remove the check box before enabling sleep.
2. Set the display attribute
1. Right-click the blank area on the desktop-properties-set "background" and "Screen Saver" to "NONE"; remove the marker "Enable Automatic desktop wallpaper conversion;
2. Right-click the blank area on the desktop-properties-appearance-effects-and remove the check box before "Use the following transition effects for menus and Tools, select "Use the following method to smooth the screen font edge"-OK.
3. Right-click the blank area on the desktop-properties-settings-"Screen Resolution" can be set to 800 × 600 or 1024 × 768; "color quality" is generally not set too high, it is better to set "medium.
4. Right-click the blank area on the desktop-properties-settings-advanced-monitor-set "screen update rate" to "-Hz", and the LCD automatically.
5. Right-click the blank area on the desktop-properties-settings-advanced-"Troubleshooting"-adjust "Hardware acceleration" to "full"-OK.
3. Disable the "Internet time synchronization" Function
Right-click the time in the notification area of the taskbar and choose "Adjust date/time"> "Internet time" to cancel the check box before "automatically synchronize with the Internet time server.
4. close some startup programs-run-msconfig-start. General programs except anti-virus software and input methods can be turned off.
5. Disable redundant Service Components
Right-click my computer> Manage> services and applications> services, and set unwanted services to disabled or manual in the right pane.
6. Shut down Dr Watson.
Click Start> Run and enter the drwtsn32 command, or "start" -- "All Programs" -- "accessories" -- "System Tools" -- "system information" -- "tools/Dr Watson" to bring up Dr Watson in the system. watson only retains the "dump all thread context" option. Otherwise, the hard disk will read for a long time and occupy a large amount of space in case of a program error.
7. Modify the Registry
1. Speed up startup and Shutdown
In [start] --> [run] --> type [Regedit] --> [HKEY_CURRENT_USER] --> [Control Panel] --> [desktop], change the value of the string value [hungapptimeout] to [200] and the value of the string value [waittokillapptimeout] to 1000. in addition, in [HKEY_LOCAL_MACHINE] --> [system] --> [CurrentControlSet] --> [control], change the value of the string value [hungapptimeout] to [200]. change the value of [waittokillservicetimeout] to 1000.
2. automatically shut down the stop Response Program
In [start] --> [run] --> type [Regedit] --> [HKEY_CURRENT_USER] --> [Control Panel] --> [desktop], change the value of the string value [autoendtasks] to 1 and restart.
3. Clear unused DLL files in the memory
In [start] --> [run] --> type [Regedit] --> [hkkey_local_machine] --> [software] --> [Microsoft] --> [windows] --> [CurrentVersion], add an item [alwaysunloaddll] in [explorer]. The default value is 1. Note: If the default value is [0], this function is disabled.
4. Speed up menu display
In [start] --> [run] --> type [Regedit] --> [HKEY_CURRENT_USER] --> [Control Panel] --> [desktop], change the value data of the string value [menushowdelay] to [0]. If you think the menu display speed is too fast, but you cannot adapt to it, you can change the value data of [menushowdelay] to [200]. restart.
5. Accelerate the auto update rate
In [start] --> [run] --> type [Regedit] --> [HKEY_LOCAL_MACHINE] --> [system] --> [CurrentControlSet] --> [control] --> [update], change the value data of DWORD [updatemode] to [0] and restart.
6. Speed up the pre-read capability and improve the boot speed
In [start] --> [run] --> type [Regedit] --> [HKEY_LOCAL_MACHINE] --> [system] --> [CurrentControlSet] --> [control] --> [sessionmanager] --> [memorymanagement], in the window on the right of [prefetchparameters], change the value data of [enableprefetcher] as follows. For example, we recommend that you change the value data to 4 or 5 when using piII 800 MHz CPU or higher, otherwise, we recommend that you retain the default value 3.
7. Use the CPU L2 cache to speed up overall performance
In [start] --> [run] --> type [Regedit] --> [HKEY_LOCAL_MACHINE] --> [system] --> [CurrentControlSet] --> [control] --> [sessionmanager], in the right window of [memorymanagement], change the value data of [secondleveldatacache] to the same decimal value as the CPU L2 cache: for example, the L2 cache of P4 1.6g A is kb, the numeric value is changed to 512 in decimal format.
8. Run the defrag program when you start the computer.
In [start] --> [run] --> type [Regedit] --> [HKEY_LOCAL_MACHINE] --> [software] --> [Microsoft] --> [dfrg] --> [bootoptimizefunction], set the string value [Enable] to Y equal to enable and N equal to disable.
9. automatically shut down the stop Response Program upon Shutdown
In [start] --> [run] --> type [Regedit] --> [HKEY_USERS] --> [. default] --> [control panel], change the value of [autoendtasks] to 1 in the right window of [desktop], and log out or restart.
10. Accelerate broadband access
In [start] --> [run] --> type [Regedit] --> in [HKEY_LOCAL_MACHINE] --> [software] --> [policies] --> [Microsoft] --> [windows ], add an item named [psched] and add a DWORD Value [nonbesteffortlimit] To the right window of [psched]. The value is 0.
11. Speed up broadband network
Open Registry Editor and find
HKEY_LOCAL_MACHINE/system/CurrentControlSet/services/TCPIP/parameters ", right-click and select "modify". The value is changed to 80 (hexadecimal) or 128 (decimal ).
Change the value of globalmaxtcpwindowsize to 7fff.
12. Acceleration of network neighbors
Open the Registry Editor and find HKEY_LOCAL_MACHINE/sofew.
