For 5 years, Microsoft made it fairly easy for users of the Windows 7 operating system to get reinstall media. If you have lost your support disc or installation retail collection; either it has been damaged or defective; You can download a copy of the edition that you have licensed from a membership site called Digital River. More recently, Microsoft ended the availability to reinstall media that you can download as a. File ISO in Digital River, which is a digital reproduction of an optical disc.

It was particularly convenient for people who could not easily get the manufacturer's recovery media, did not want to pay the fees required to get or preferred a clean configuration without the software packaged manufacturers or even a recovery partition does not work. It's easy to use, all you had to do was reinstall and reactivate using the product key located on the certificate of authenticity and download all the drivers on the manufacturers website.

Given that this option is no longer available, what are your options? See the article for more details:

How to: What are my options for Windows 7 reinstall media?

Make sure you scroll down and read the section:

What to do if you cannot get your manufacturer recovery media, refuse to use or to buy it or the Microsoft Software Recovery Website does not work?

  • How to reinstall the Windows 7 upgrade on vista for new installation or in the event of system failure?

    I love periodically re - install a new operating system after reformatting hadr drive. In the past it was the of syetem of full operation and not just an upgrade. I have to be sure that it is not complicated, as I want to install the upgrade to Windows 7 (family pack) on 3 PC/laptops running Vista. I would upgrade as detailed instructions on how I would do a new installation using the Windows 7. This is important because I don't want to create a nightmarish experience of backup, install the original operating system, install the upgrade, etc. etc. etc.

    If you upgrade a computer Vista Win7 and need or want to do a clean install (or repair install) of Windows, you will need to reinstall Vista and then switch to Win7 again.

    Your question has nothing to do with Windows Update.

  • How to reinstall the windows XP printer folder I don't have the reinstallation discs

    It seems that the computer can not find the print file is probably corrupted
    . I have reinstall the driver, but in Device Manager it shows nothing for printer.

    [Moved from comments]

    If you mean that the printers and Faxes window is empty and that you can not install a printer by clicking Add a Printer Wizard, then the print spooler does not work, probably because you have a printer driver damaged or corrupted a print job.

    There is an easy solution for the above, but rather than confusing things by providing a solution to something that may not be your problem, please explain what you mean by "cannot find the file to print."

    Explain how you have reinstalled the driver.

    Generally printers do not appear in Device Manager.  They are shown (and configured) in the windows printers and fax machines.

    What version of Windows XP (Home, Pro, Media Center) and service pack (none, 1, 2, 3) do you have?

    What is the name and version of your anti-virus program?

    What other security programs installed?

    You had an option pre-installed on your laptop that you helped to create the recovery disk. Seems you didn't create this disk in the past

  • How do reinstal windows xp?

    my laptop is running slow (OS Win XP) and I want reinstal windows xp on it can you tell me how I have an xp disk and license, I've never done this before, so easy to understand instructions could be very useful.

    linbeck

    I recommend to install Windows on if you've never done before and expect to get back to a fully functional computer before the end of the week is over. ;-)

    The basics are simple:

    • Back up all important data you external to the computer in question.
    • Make sure you have all the serial numbers and installation support and product keys set - off the computer in question.
    • Make sure you know all the hardware on your system.  Run and print the Belarc Advisor report to be sure.  I recommend to download the latest drivers for each piece of hardware NOW and their storage on a reader of CD/DVD/USB external to the computer for later.
    • Change your CMOS/BIOS system to boot from the CD and start with the support of Windows XP (CD).
    • Follow the prompts, remove the existing divides and create new partition on which to install the operating system.
    • When installing the operating system, install the drivers for hardware devices.
    • When doing this, patch Windows XP OS by http://windowsupdate.microsoft.com/ (repeat until there is no critical update left - leave EVERYTHING the only option at the moment.)
    • When doing this, install your applications.  Then update those.
    • Restoring your data.

    However - I think you'd be better of just clean up.

    Search for malware:

    Download, install, execute, update and perform analyses complete system with the two following applications:

    Remove anything they find.  Reboot when necessary.  (You can uninstall one or both when finished.)

    Search online with eSet Online Scanner.

    The less you have to run all the time, most things you want to run will perform:

    Use Autoruns to understand this all starts when your computer's / when you log in.  Look for whatever it is you do not know using Google (or ask here.)  You can hopefully figure out if there are things from when your computer does (or connect) you don't not need and then configure them (through their own built-in mechanisms is the preferred method) so they do not - start using your resources without reason.

    You can download and use Process Explorer to see exactly what is taking your time processor/CPU and memory.  This can help you to identify applications that you might want to consider alternatives for and get rid of all together.

    Do some cleaning and dusting off this hard drive:

    You can free up disk space (will also help get rid of the things that you do not use) through the following steps:

    Windows XP should take between 4.5 and 9 GB * with * an Office suite, editing Photo software, alternative Internet browser (s), various Internet plugins and a host of other things installed.

    You can disable hibernation if it is enabled and you do not...

    When you Hibernate your computer, Windows saves the contents of the system memory in the hiberfil.sys file. As a result, the size of the hiberfil.sys file will always be equal to the amount of physical memory in your system. If you don't use the Hibernate feature and want to reclaim the space used by Windows for the hiberfil.sys file, perform the following steps:

    -Start the Control Panel Power Options applet (go to start, settings, Control Panel, and then click Power Options).
    -Select the Hibernate tab, uncheck "Activate the hibernation", and then click OK. Although you might think otherwise, selecting never under "Hibernate" option on the power management tab does not delete the hiberfil.sys file.
    -Windows remove the "Hibernate" option on the power management tab and delete the hiberfil.sys file.

    You can control the amount of space your system restore can use...

    1. Click Start, right click my computer and then click Properties.
    2. click on the System Restore tab.
    3. highlight one of your readers (or C: If you only) and click on the button "settings".
    4 change the percentage of disk space you want to allow... I suggest moving the slider until you have about 1 GB (1024 MB or close to that...)
    5. click on OK. Then click OK again.

    You can control the amount of space used may or may not temporary Internet files...

    Empty the temporary Internet files and reduce the size, that it stores a size between 64 MB and 128 MB...

    -Open a copy of Microsoft Internet Explorer.
    -Select TOOLS - Internet Options.
    -On the general tab in the section 'Temporary Internet files', follow these steps:
    -Click on 'Delete the Cookies' (click OK)
    -Click on "Settings" and change the "amount of disk space to use: ' something between 64 MB and 128 MB. (There may be many more now.)
    -Click OK.
    -Click on 'Delete files', then select "Delete all offline content" (the box), and then click OK. (If you had a LOT, it can take 2 to 10 minutes or more).
    -Once it's done, click OK, close Internet Explorer, open Internet Explorer.

    You can use an application that scans your system for the log files and temporary files and use it to get rid of those who:
