How to avoid autoplay of CD ?

Hey this time no registry trick even though there are ways in registry to do it. In earlier operating systems only those CD that had autorun.inf file in their root directory were able to execute on its own but with advent of WINDOWS XP it has become possible with just about anything. Well sometimes it is good but there are other times when you want to avoid this part of automation. What would I do. Simply press SHIFT key when you enter a CD in your CD drive. It won't Auto play. For those of you, who do want a registry hack. Here it is: Open Registry and navigate to [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\Curr entVersion\policies\Explorer] and look for key "NoDriveTypeAutoRun" and set its value to 185 (decimal). This would stop autoplay.

Gain temp access to Administrative privileges even if you are not logged in as administrator.

I must be telling you one thing. In most of the cases where Windows XP is installed on a personal computer, users generally have access to administrative account. But you know, it is not in your best interest to log on as administrator for all your computing needs. I must advise you to create a normal user account as well. But what if you are logged in as normal user and happen to download/install some software application that would need administrative privileges Here is the solution. Simply right click on the executable and select run as. You would see a window poping up. Here you can provide one of the userid/password that would have admin privileges That's all you need to run that program with administrative privileges

How to determine a 16 bit application from a 32 bit application ?

Old 16 bit app are still useful and are in use by many. I think this is the result computer evolution. If You want to know whether a particular executable is a 16 bit or 32 bit application, here is a secret. Right-click the program’s executable file and Then choose Properties. If You see a Version tab, it’s a 32-bit program else its a 16-bit program. Alternately You can go into task manager and look for applications that have ntvdm.exe (virtual dos machine) in the name column of process tab. If there is one, it means its a 16 bit app.

Do You know how to add/delete entries in Control Panel ? Heard about CPL extension ?

If You open windows explorer and search for all *.cpl files, You would see at least as many entries in search as You have in your control panel.Yes ! .cpl stands for control panel. If You do not want to navigate to any of your favorite entries, You can create a shortcut to that entry's corresponding cpl file. Following lists control panel and cpl file names:
System Properties = sysdm.cpl
Network Connections = ncpa.cpl
ODBC Administrator = odbccp32.cpl
Display Properties = desk.cpl
Add or remove programs = appwiz.cpl
Internet Properties = Inetcpl.cpl
Game Controllers = joy.cpl
Phone and modem Options = telephon.cpl
Time and Date Properties = timedate.cpl
Region and Language Options = intl.cpl
Power Options = powercfg.cpl
Mouse Properties = main.cpl
Accessibility Options = access.cpl
Add Hardware Wizard = hdwwiz.cpl
Sound and Audio Devices = mmsys.cpl
User Accounts = nusrmgr.cpl
Speech Properties = sapi.cpl
Now if You want to add/delete any of these entries from panel You can do it through Registry or gpedit.msc or through tweakui if You have powertoys installed. It is preferable to use gpedit or TweakUi as its easier.
From TweakUi, You have to simply click on control panel , and select/deselect entries in right panel as per your choice.
From gpedit.msc (to run gpedit, goto START-RUN and type gpedit.msc) Navigate to User Configuration- Administrative Templates-Control Panel folder select and right click on Show only specified Control Panel Applets , click on enabled and Then click on the show. In this list You won't see anything if its your first time. Click on add and type the complete file name from above list. (This is a bit more complicated process specially if You are a new user of the tool)
And if You are a registry fan, You can do this my navigating to [HKEY_CURRENT_USER\Control Panel\] and adding a key field by the name "don't load" and one string value to each of the cpl file names. For example if You don't want to see accessibility options, add a string "access.cpl" on the right pane to the newly added key field "don't load". You can add as many strings You want.

Have a IDE drive ? Improve disk performance by changing to DMA access mode

If You are an average user, there is a good chance that your are using a IDE hard disk that supports DMA access. Even Windows XP fails to set the DMA mode correctly for the IDE device designated as the slaves on the primary IDE and secondary IDE channels. Most CD-ROMS are capable of supporting DMA mode, but the default in XP is still PIO. Setting it to DMA won't make your CD-ROM faster, but it will consume less CPU cycles. Follow instructions below:
1. Open the Device Manager and navigate to "IDE ATA/ATAPI Controllers", expand it and double-click on "Primary IDE Channel"
2. Under the "Advanced Settings" tab, verify the "Device 1" setting. If transfer mode is set to PIO Then set it to "DMA if available". Repeat the step for the "Secondary IDE Channel" if You have devices attached to it. Reboot the sytem.

Low on disk space and do not use Windows XP Hibernate feature ?

With hardware prices going down every passing day You may not need this tip but if You are in a situation where You are really low on disk space even after using disk cleaner, one of the things You can do is to identify features of XP You don't use. It may very well be the hibernate feature. If You don't use it, simply disable it and get as much of hard disk space free as is your physical RAM size. To do that go to power options in control panel (fast route: goto START-RUN or win+R and type powercfg.cpl ) and click on hibernate tab and deselect "enable hibernation".

Lock known dll's list and make your computer a bit more safer

Folks, You may be wondering that I am talking about making your computer a bit more safer even though my very site was hacked on 1/14/2002. As it stands I have kept this site simple and I do not control the webhosting part. Anyway it is a good idea to keep your computer safe.Open Registry by going to START-RUN and entering REGEDIT and Navigate to [HKEY_LOCAL_MACHINE\System\CurrentControlSet\Contro l\Session Manager] and look for ProtectionMode parameter. If its value is not 1 , set it to value of 1. On my computer default value is 1. Doing this will protect your list of known system dlls from being compromised. To see what is present in your known DLL list, navigate to [HKEY_LOCAL_MACHINE\System\CurrentControlSet\Contro l\Session Manager\KnownDLLs] and look in the right pane. I have not yet tried this but You may even try adding some other DLLs that You feel important and should be protected. This could be risky as I have not yet tried this myself.
Microsoft has an old but informative article on it http://support.microsoft.com/support.../q218/4/73.asp

Improve computer performance by reducing EFS cache validation

Navigate to HKLM\System\CurrentControlSet\Services\NTFS\EFS\Pa rameters and set the parameter of EFSKCACHEPERIOD to a value between 2 and 30. default is 5. Value suggest the time in seconds the kernel will cache the session key for a user for a given file. The Kernel will not validate the user credentials during this cache period. This has the net effect of faster access to encrypted files that may be opened several times during a given time period.This is helpful in kernel and user mode of the EFS (encrypting file system) as it provides quicker access to frequently use components.
Similarly navigate to HKLM\Software\Microsoft\Windows NT\CurrentVersion\EFS and set the value of KeyCacheValidationPeriod to a value in units of second from 1 minute to 1 day (60 to 86400).
