修xiu正zheng

1．补bu丁ding及ji驱qu动dong。不bu管guan怎zen么me说shuoWinXP比biP4和heAthlonXP以yi及ji与yu其qi搭da配pei的de芯xin片pian组zu推tui出chu的de时shi间jian要yao早zao，所suo以yi为wei保bao证zheng向xiang后hou的de兼jian容rong性xing和he稳wen定ding性xing，应ying当dangUPdale一yi下xia，打da全quan相xiang关guan的de补bu丁ding，还huan有you就jiu是shi主zhu板ban相xiang应ying的de驱qu动dong亦yi是shi必bi不bu可ke少shao的de，例li如ruIntel的deIAA和heVIA的de4inl驱qu动dong，这zhe也ye是shi保bao证zhengATAl33、AGP4X等deng特te性xing正zheng常chang使shi用yong的de基ji本ben前qian提ti。

2．CPU Cache修xiu正zheng。WinXP对duiCPU二er级ji缓huan存cun大da小xiao的de识shi别bie真zhen的de很hen蹩bie脚jiao，识shi别bie居ju然ran为wei“0”!不bu过guo我wo们men只zhi要yao运yun行xing“Regedit”，在zai“[HKEY-LOCAL-MACHINE＼SYSTEM＼CurrentControlSet＼Control＼Session Manager＼MemoryManagement＼SecondLevelDataCache]”中zhong按an十shi进jin制zhi输shu人ren相xiang应yingCPU二er级ji缓huan存cun的de大da小xiao就jiu可ke以yi让rangWinXP正zheng确que识shi别bieL2Cache了le。（AthlonXP为wei256，AthlonXP Barton核gai心xin的de为wei512，毒du龙long为wei64，P4的de为wei512，赛sai扬yang为wei128）

IDE的de设she置zhi

1．关guan闭bi不bu用yong的deIDE端duan口kou。WinXP每mei次ci启qi动dong都dou会hui检jian测ce全quan部bu的deIDE设she备bei，在zai空kong闲xian的de端duan口kou上shang这zhe很hen浪lang费fei时shi间jian。右you击ji我wo的de电dian脑nao，选xuan属shu性xing，点dian选xuan硬ying件jian选xuan项xiang，点dian击ji“设she备bei管guan理li器qi”，分fen别bie进jinPrimary和heSecondIDEChannel属shu性xing，把ba不bu用yong的deDeviceType改gai成chengNone。

2．设she置zhiIDE设she备bei的deDMA模mo式shi。出chu于yu某mou些xie原yuan因yin，WinXP有you时shi不bu会hui使shi用yongDMA模mo式shi。右you击ji我wo的de电dian脑nao，选xuan属shu性xing，点dian选xuan硬ying件jian选xuan项xiang卡ka，点dian击ji“设she备bei管guan理li器qi”，然ran后hou展zhan开kai“IDEATA／ATAPI控kong制zhi器qi” 分fen支zhi，双shuang击ji“ Primary IDE Channel”，点dian击ji高gao级ji设she置zhi。检jian查cha“传chuan输shu模mo式shi”下xia拉la菜cai单dan，把ba它ta们men全quan部bu设she为weiDMA If Available(允yuan许xu情qing况kuang下xia使shi用yongDMA)，点dian击ji确que定ding。再zai用yong同tong样yang的de方fang式shi修xiu改gai每mei一yi个geIDE控kong制zhi器qi。

注zhu册ce表biao优you化hua

1．内nei存cun性xing能neng优you化hua。WinXP中zhong有you几ji个ge选xuan项xiang可ke以yi优you化hua内nei存cun性xing能neng，它ta们men全quan都dou在zai注zhu册ce表biao如ru下xia位wei置zhi：HKEY-LOCAI-MACHINE＼SYSTEM＼CurrentControlSet＼Control＼Session Manager＼Memory ManagementDisable Paging Executive(禁jin止zhi内nei存cun页ye面mian调tiao度du)。在zai正zheng常chang情qing况kuang下xia，WinXP会hui把ba内nei存cun中zhong的de片pian断duan写xie入ru硬ying盘pan，我wo们men可ke以yi阻zu止zhi它ta这zhe样yang做zuo，让rang数shu据ju保bao留liu在zai内nei存cun中zhong，从cong而er提ti升sheng系xi统tong性xing能neng。要yao注zhu意yi的de是shi，只zhi有you拥yong有you256M以yi上shang内nei存cun的de用yong户hu才cai能neng使shi用yong这zhe个ge设she置zhi，把ba它ta的de值zhi从cong0改gai为wei1就jiu可ke以yi禁jin止zhi内nei存cun页ye面mian调tiao度du了le。

再zai将jiangLargeSystemCache(加jia大da系xi统tong缓huan存cun)的de键jian值zhi从cong0改gai为wei1，WinXP就jiu会hui把ba除chu了le4M之zhi外wai的de系xi统tong内nei存cun全quan部bu分fen配pei到dao文wen件jian系xi统tong缓huan存cun中zhong，这zhe意yi味wei着zheXP的de内nei核gai能neng够gou在zai内nei存cun中zhong运yun行xing，大da大da提ti高gao系xi统tong速su度du。而er剩sheng下xia的de4M内nei存cun是shi用yong来lai做zuo磁ci盘pan缓huan存cun的de，在zai一yi定ding条tiao件jian下xia需xu要yao的de时shi候hou，WinXP还huan会hui分fen配pei更geng多duo一yi些xie。一yi般ban来lai说shuo，这zhe项xiang优you化hua会hui使shi系xi统tong性xing能neng得de到dao相xiang当dang的de提ti升sheng，但dan也ye有you可ke能neng会hui使shi某mou些xie应ying用yong程cheng序xu性xing能neng降jiang低di。正zheng如ru前qian面mian所suo说shuo的de，必bi须xu有you256M以yi上shang的de内nei存cun，才cai能neng激ji活huoLargeSystemCache，否fou则ze不bu要yao动dong它ta。

2．不bu加jia载zaiDll,文wen件jian。浏liu览lan器qi在zai使shi用yong之zhi后hou往wang往wang会hui有you部bu分fenDll,文wen件jian在zai内nei存cun中zhong留liu驻zhu很hen长chang一yi段duan时shi间jian，就jiu使shi得de相xiang当dang一yi部bu分fen内nei存cun会hui被bei不bu需xu要yao的deDll文wen件jian占zhan用yong，降jiang低di了le内nei存cun的de效xiao率lv。为wei了le防fang止zhi这zhe种zhong事shi情qing发fa生sheng，我wo们men可ke以yi找zhao到dao注zhu册ce表biao里li的deHKEY-LOCAL-MACHINE＼SOFFWARE＼Microsoft＼Windows＼CurrentVersion＼Explorer，并bing建jian立li一yi个ge名ming为weiAlwaysUnloadDll，值zhi为wei1的de双shuang字zi节jie值zhi。

3．快kuai速su关guan机ji。修xiu改gai几ji个ge注zhu册ce表biao键jian值zhi，就jiu可ke以yi大da大da减jian少shaoWindows关guan闭bi所suo用yong的de时shi间jian。打da开kaiRegedit，找zhao到daoHKEY-CURRENT-USER＼ControlPanel＼Desktop＼，里li面mian有you个ge名ming为weiHungAppTimeout的de键jian，它ta的de值zhi应ying该gai是shi5000(默mo认ren值zhi，如ru果guo不bu是shi，把ba它ta改gai为wei5000)。接jie下xia来lai，还huan有you个geWaitToKillAppTimeout键jian，把ba它ta的de值zhi改gai为wei4000(默mo认ren值zhi是shi2000)。最zui后hou，找zhao到dao注zhu册ce表biao如ru下xia位wei置zhi： HKEY-LOCAL-MACKqNE＼ System＼ CurrentControlSet＼Control＼，同tong样yang的de把ba其qi中zhong的deWaitToKillServiceTimeout键jian值zhi改gai为wei4000就jiu可ke以yi了le。 另ling外wai，把ba控kong制zhi面mian版ban一yi管guan理li工gong具ju一yi服fu务wu中zhong的deNVidia DriverHelp服fu务wu设she为wei手shou动dong，也ye可ke以yi加jia快kuaiWindows关guan闭bi时shi间jian，当dang然ran这zhe只zhi对dui应yingNvidia显xian卡ka。

4．提ti高gao预yu读du。WinXP使shi用yong预yu读du这zhe一yi新xin技ji术shu，以yi提ti高gao系xi统tong速su度du。运yun行xing“Regedit”，在zai[HKEY-LOCAL-MACHINE＼SYSTEM＼CurrentControlSet＼Control＼Session Manager＼Memory Management＼PrefetchParameters＼EnablePrefetcher]中zhong设she置zhi数shu值zhi为wei“5”，默mo认ren是shi“3”。“0”代dai表biao不bu预yu读du，“1”代dai表biao预yu读du应ying用yong程cheng序xu，“2”代dai表biao启qi动dong预yu读du，“3”代dai表biao前qian两liang者zhe皆jie预yu读du。注zhu意yi：使shi用yong一yi段duan时shi间jian后hou，预yu读du文wen件jian夹jiaC：＼Windows＼Prefetch里li的de文wen件jian会hui多duo出chu来lai占zhan用yong磁ci盘pan空kong间jian，可ke定ding时shi清qing除chu。

5．启qi动dong设she置zhi。修xiu改gai一yi些xie默mo认ren的de启qi动dong设she置zhi对dui提ti高gao速su度du至zhi关guan重chong要yao。右you击ji“我wo的de电dian脑nao”一yi“属shu性xing”一yi“高gao级ji”一yi“启qi动dong和he故gu障zhang修xiu复fu”，点dian“错cuo误wu报bao告gao”，选xuan择ze“禁jin用yong错cuo误wu汇hui报bao”、“但dan在zai发fa生sheng严yan重chong 错cuo误wu时shi通tong知zhi我wo”；去qu掉diao“将jiang事shi件jian写xie入ru系xi统tong日ri志zhi”、“发fa送song管guan理li警jing报bao”、“自zi动dong重chong新xin启qi动dong”选xuan项xiang；将jiang“写xie入ru调tiao试shi信xin息xi”设she置zhi为wei“无wu”；点dian击ji“编bian辑ji”，在zai弹tan出chu记ji事shi本ben文wen件jian中zhong把ba [Operating Systems] Timeout=30的de30秒miao改gai为wei0秒miao，把baMulti(0) Disk(0)Rdisk(0)Partition(1)＼Windows=“Microsoft Windows XP Professional”／Fastdetect的deFastdetect改gai为weiNodetect。

6．虚xu拟ni内nei存cun。将jiang虚xu拟ni内nei存cun值zhi设she为wei物wu理li内nei存cun的de2．5倍bei，512M以yi上shang可ke改gai用yong1．5倍bei或huo1倍bei。初chu始shi大da小xiao和he最zui大da值zhi设she为wei一yi样yang，这zhe样yang有you助zhu于yu提ti高gao性xing能neng。注zhu意yiCPU及ji内nei存cun要yao给gei应ying用yong程cheng序xu使shi用yong，只zhi有you服fu务wu器qi才cai需xu要yao给gei后hou台tai使shi用yong。如ru果guo对dui自zi己ji系xi统tong内nei存cun不bu是shi很hen清qing楚chu的de朋peng友you建jian议yi默mo认ren。

7．修xiu改gai磁ci盘pan缓huan存cun。磁ci盘pan缓huan存cun对duiWinXP运yun行xing起qi着zhe至zhi关guan重chong要yao的de作zuo用yong，但dan是shi默mo认ren的deI／0页ye面mian文wen件jian比bi较jiao保bao守shou。所suo以yi，对dui于yu不bu同tong的de内nei存cun，采cai用yong不bu同tong的de磁ci盘pan缓huan存cun是shi比bi较jiao好hao的de做zuo法fa。运yun行xing “Regedit”到dao[HKEY-LOCAL-MACHINE＼SYSTEM\CurrentControlSet＼Control＼Session Manager＼Memory Management＼IoPageLockLimit]，根gen据ju你ni的de内nei存cun修xiu改gai其qi十shi六liu进jin制zhi值zhi，64M为wei1000、128M为wei4000、256M为wei10000、512M或huo更geng大da为wei40000。

关guan闭bi不bu必bi要yao的de功gong能neng。

系xi统tong还huan原yuan是shi非fei常chang不bu实shi用yong的de，建jian议yi将jiang其qi关guan闭bi，提ti高gao性xing能neng不bu说shuo，节jie约yue的de空kong间jian还huan可ke以yi用yong来lai做zuoGhost镜jing像xiang。要yao关guan闭bi系xi统tong还huan原yuan功gong能neng，右you击ji“我wo的de电dian脑nao”一yi“属shu性xing”一yi“系xi统tong还huan原yuan”，选xuan“在zai所suo有you的de驱qu动dong器qi上shang关guan闭bi系xi统tong还huan原yuan”。要yao关guan闭bi自zi动dong更geng新xin，右you击ji“我wo的de电dian脑nao”一yi“属shu 性xing”一yi“自zi动dong更geng新xin”，选xuan择ze“关guan闭bi自zi动dong更geng新xin，我wo将jiang手shou动dong更geng新xin计ji算suan机ji”。关guan闭bi远yuan程cheng桌zhuo面mian，右you击ji“我wo的de电dian脑nao”一yi“属shu性xing”一yi“远yuan程cheng”，“远yuan程cheng桌zhuo面mian”里li的de “允yuan许xu用yong户hu远yuan程cheng连lian接jie到dao这zhe台tai计ji算suan机ji”勾gou掉diao。

关guan闭bi多duo余yu的de服fu务wu。

每mei次ciWinXP启qi动dong之zhi后hou，随sui之zhi也ye启qi动dong了le许xu多duo服fu务wu程cheng序xu，有you些xie服fu务wu程cheng序xu对dui于yu大da多duo数shu用yong户hu来lai说shuo是shi没mei用yong的de，空kong占zhan用yong了le内nei存cun，因yin此ci关guan掉diao它ta们men是shi很hen好hao的de选xuan择ze。点dian击ji“开kai始shi”一yi“运yun行xing”，输shu人ren命ming令ling“Services.msc”，打da开kai “服fu务wu”对dui话hua框kuang，会hui出chu现xian下xia面mian的de一yi些xie程cheng序xu：
