Tune UR XP.. Tips

1. Fine tune Internet connection speed:
Tip on changing QoS parameter.This tweak deals with QoS parameter manipulation. There have been some confusion as to what can be achieved in real terms by changing the QoS parameter. Microsoft has finally released an article correcting describing the behavior of QoS parameter. In brief though, this tweak would only work on QoS aware programs and rest of the programs would simply ignore them. Networking Quality of Service (QoS) refers to a variety of techniques that prioritize one type of traffic or program when these operate across a network connection rather than relying solely on "best effort" connectivity. By default, programs can reserve up to an aggregate bandwidth of 20 percent of the underlying link speed on each interface on an end computer. If the program that reserved the bandwidth is not sending enough data to utilize it completely, the unused portion of the reserved bandwidth is available for other data flows on the same host. This default parameter can be changed.


2. Further fine tune Internet access speed:
Tip on improving DNS resolution. Internet browsing is such an exciting and easy experience now a days that we have almost forgotten the amount of work that goes behind the scene to make this all happen. We only feel bad if we can't find something easily or have to wait for a long time (I have heard many people saying WWW stands for world wide wait not too long ago!!!) Well with changes in technology and falling prices we have far better hardware and software to do this job but fruits of fine tuning have always been great and would continue to remain so. One of the things that should happen before Internet connection would go through is DNS resolution.DNS stands for Domain Name Service. Even though XP does a fine job of handling DNS resolution, you may still gain by increase the DNS Cache size. To do this you would have to add following entries in registry. Save what is written below in say "dnstuning.reg" file and import it in REGISTRY but opening registry editor and going to IMPORT option from top menu. [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Dnscache\Parameters]"CacheHashTableBucketSize"=dword:00000001"CacheHashTableSize"=dword:00000180"MaxCacheEntryTtlLimit"=dword:0000fa00"MaxSOACacheEntryTtlLimit"=dword:0000012d

3. Start menu is slow in responding? Want to boost response time of start menu ?
Windows XP is touted as a new generation of OS Xperience. No doubt about that but this experience come at a cost. Resources. If your hardware configuration (read CPU,RAM) is not upto speed but still want to boost response time of start menu, here are a few tricks that might help. Open registry editor by going to START-RUN and entering regedit and navigate to key HKEY_CURRENT_USER \ Control Panel \ Desktop \ MenuShowDelay . Change the value (default may be 400) to 5 or 50 or even 0. This should speed up. If you are not all that crazy for shadowy effects, you can further speed the things up by going to DISPLAY Properties Window and from there to appearance and over there clicking Advanced command button and check off Show menu shadow.
4. Want to enhance Network throughput?
Network throughput depends on a variety of factors and as such you never no what could be the bottleneck. One of things that we can try out is the network redirector reserves.Open registry editor by going to START-RUN and entering regedit and navigate to key [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\LanmanWorkstation\Parameters]. One here, click on right pane and added following Dwords. Dwords are in hexadecimal (and value as shown below indicates that of 104, valid values are 0-255). Keep both values same. I think default is 15 or 20. This may help networkthrough put but there is no guarantee. Try it out."MaxCmds"=dword:00000068"MaxThreads"=dword:00000068

5. What to do with "the system has recovered from a serious error......" error ?
Whenever Windows XP encounters a problem (that it thinks is serious even if you did not do anything unusual) it creates a dump file. Next time you reboot, you most likely see this error message. Clicking on more information shows error signature and other clumsy details. Typically minidump would be stored in \WINDOWS\MINIDUMP directory. It is not so easy to decipher this information. Temporarily disabling error reporting:Right-clock on my computer, select properties, advanced tab, error reporting button - turn on the "no error reporting" check box and turn off the "but notify me" option. Disable Virtual Memory:Right-click on my computer, select properties, advanced tab, performance settings, advanced tab, virtual memory "change" button. Note down the current VM settings (system managed or any customized size. Turn on the "no paging file" bullet, and press the set tab. Delete the paging file:Reboot. Verify that the option reads 0 kb for page file. Use folder options on control panel or explorer "tools" pulldown menu & go to "view" tab. Turn off check box to permit viewing of system files. Now explorer on the root of C drive (or what ever drive letter you page file was set to use), should show a pagefile.sys entry. Delete this. You will get a warning message about this being a system file. Since you have disabled virtual memory, this entry is not being used. Delete it. Go empty the trash bin to make sure this entry is cleared. Re-enable Virtual Memory:Right-click on my computer, select properties, advanced tab, performance settings, advanced tab, virtual memory "change" button , turn on the system-managed or customized paging file with the same settings as you noted down earlier. Be sure to press the set button. Reboot and verify that the paging file is active. Re-enable error reporting that was disabled earlier. Reboot to verify that the repetitive error message has indeed "left the building" IMPORTANT NOTE: Microsoft support team should contact you as soon as possible!


6. NetMeeting does not open up quickly or not at all?
If you have recently bought/installed the XP PRO on your PC (which had been the case with me) you may not have activated netmeeting. You would have to do that. Quickest would be to go to START-RUN and entering CONF and in the resultant screen, providing basic information about your self and your are done.

7. DVD-RAM model supported in XP but not being recognized or being recognized as CD-ROM?
Open Regedit by going to START - RUN and type Regedit and hit enter. Then you should navigate to following entry in registryHKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\ {4D36E965-E325-11CE-BFC1-08002BE10318}. Highlight the {4D36E965-E325-11CE-BFC1-08002BE10318} folder in the left pane, delete the following two keys in the right pane."UpperFilters""LowerFilter"DELETE these two entries and restart your computer. If your DVD-RAM is supported by WINDOWS XP, this may work.

Solution for "Orkut Banded Virus"

They blocked mozilla coz they couldnt read the edit fields in it through autohotkey, so forced the user to use ie or opera only.

If its not detected by the antivirusRun the task manager,in processes tab you'll see two processes svchost.exe running under your user name, end them. then go to
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\Current Version\policies\Explorer\Rundelete winlogon key

you better leave the status key, coz i made the virus first check this key, if present it'll not install then go to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\Curr entVersion\Explorer\Advanced\Folder\Hidden\SHOWALL
here set the checked value to 1

AND IF you are not administrator, the virus couldnt access the registry, so they created startup shortcuts in startmenu. you'll see an invisible icon in the startup menu of start menu, delete it
DO ALL THIS AFTER YOU END THE TWO PROCESSES otherwise they'll be RESTORED every 10 seconds

After all this go to folder options uncheck hide protected filesyou'll see C:\heap41a folder, delete it and you'll see microsoftpowerpoint.exe in your pen drives along with autorun.inf , delete them
