ok recently i needed to use cmd for something ,and when i typed cmd into run it said cmd was missing so i went into my system32 folder and saw that it was deleted somehow ,so im asking is there a way to reset it so it appears again or how would i be able to get it back ,ive looked every where for an answer to this but never found andy answers or help ,i contacted microsoft about a month ago and yesterday i got an email from them just saying to search their FAQ ,but i looked through the whole thing and found nothing ,so in advanced thank you for your time and your help.

Unless vista is different cmd is required for your computer to work.
Click on start -> All Programs -> Accessories and you will see command prompt.

is it an OS file? they're hidden if it is.

I love your handle! It's very creative.

What Roy states is correct. If you believe this program has somehow become corrupt, there are TWO options. You can run the "System Restore Wizard" by clicking the Windows key, then clicking on Help, then typing "System Restore Wizard" in the search window. When the Wizard loads you will be asked if you want to "Restore the PC to an earlier time." Select yes or whatever the appropriate option is on this window and click "Next." You will then be asked to select a "Restore Point." Think back to the last time your computer worked correctly, then select a restore point equal to or prior to that date and click "Next." Your PC will restore itself to working condition.

If the above doesn't work, your OTHER option is to perform an "In-Place-Upgrade." What this involves is inserting your installation disk, instructing it to install Windows and when asked select the option to perform an "Upgrade" rather than a "Clean Install." This will leave your files & programs alone. What it will do, that may not be desireable, is overwrite all your Windows updates and reset your registry. So, if you've performed any registry hacks, for instance., to put Internet Explorer on the Desktop or set the default Internet Explorer to the 64 bit version, then you will have to do these all over again.

Once you get your system stabilized again, I recommend purchasing an external USB HDD and performing a "Complete PC Backup" on a regular basis. This way, if you have any of these problems in the future, all you'll have to do to recover is insert the Installation DVD and select "Repair Computer," then select "Complete PC Restore" from the menu and your PC will be as good as new.
