  • Why Windows 8 allow me to remove the Windows.old folder?

    I upgraded my computer to Windows 7 to Windows 8, a few months ago, when Windows 8 came. It is my understanding that when you perform an upgrade of Windows from one version to the other, it can save a lot of files and folders under the folder Windows.old. And I understand that you can delete the Windows.old folder.

    In other words, I don't think.

    The reason why I do not think it is because whenever I tried to delete Windows.old, it stops for me with this error:

    And when I said to 'Try Again' he begins from the beginning? HE DOES ALL THIS TIME! This should not do this, as I did do procedure on other machines that I've updated and he's NEVER done that, but not on this machine? Why in hell does?

    Hello

    Thanks for posting your question in the Microsoft Community Forums.

    No need to worry, we're here to help you and guide you in the right direction.

    The windows.old folder is the old system files. Be sure to copy all the files that you can out of the Windows.old folder before you delete it. Once deleted, they are gone. You must be logged in as an administrator to be able to do the steps.

    The Windows.old folder contains the following folders:

    • Windows
    • "Documents and Settings".
    • "Program Files."

    The Windows folder stores mainly programs and files that are required to run the previous version of Windows.

    The "Documents and Settings" folder stores mainly the 'My Documents' folder and the Favorites folder. In addition, the "Documents and Settings" folder stores the office files that have been used by the previous version of Windows.

    The "Program Files" folder stores mainly programs have been installed on the earlier version of Windows.

    There are two ways to delete the windows.old folder. Here is the simple step.

    Method 1: Delete the C drive.

    (a) open Windows Explorer, click computer.

    (b) select C drive and you will find the Windows.old folder.

    (c) make a right click on the folder and click Remove.

     

    Method 2: Remove the "Windows.old" folder using disk cleanup

    (a) open Disk Cleanup by clicking on the button Windows + C to open the bar of charms. Click on the charm of the Search .

    (b) type cleanmgr in Search Applications box in the right pane, and then click cleanmgr.exe (disk cleanup) in the left pane to open it.

    (c) If you are prompted to choose a drive, click the drive that you have just installed Windows on and then click OK.

    (d) in the Disk Cleanup dialog box, on the Disk Cleanup tab, click clean up system files.

    (e) If you are again prompted to choose a drive, click the drive that you have just installed Windows on and then click OK.

    (f) select the Previous Windows installations check box and the other check boxes for files that you want to remove, and then click OK.

  • files and folders in the windows.old folder missing

    Recently, I updated my windows 8. (a day and a half)

    Today I was moving the content in the folder windows.old to the other locations, (4 ~ 5 h ago)

    Suddenly, after the computer has restarted, the content in the windows.old folder disappeared except for users and windows folders.

    I copy the files from windows.old/Program files and I don't know that I do not delete the folder by myself.

    I read previous posting on similar problems, but that's because they kept their too long files or their disk space was not enough.

    But I have enough space in my C drive and just refreshed 1 ~ 2 days ago.

    I did not drive or any cleaning that is.

    It is unreasonable to a system to remove the backup files after a few days without noticing.

    Please let me know how to solve this problem and to recover these files.

    There are a lot of files in the previous program files, I need to recover the precious.

    Hi Junwhan,

    Thanks for posting your query in Microsoft Community.

    I can understand the importance of data could be in the Windows.old folder and we regret the inconvenience.

    Yes, Windows 8 has a new timer feature which will automatically delete Windows.old files after a period of 4 weeks since the upgrade. The idea is to avoid the waste of space giving you plenty of time to get what you need out of the folder and delete those that sit for months or even years.

    Since it's just been 1-2 days of update process, you can activate the "hidden objects" to see if the Windows.old files appear.

    As you open the file Explorer, click view and check the hidden items

    In addition, if you use third-party antivirus program control the log of activities see if there is any action taken at the time where the files have disappeared.  Most of the antivirus program automatically deletes the default files. You can change these settings, however, it is not recommended.

    If you use the default, Windows Defender (WD) on Windows 8.1 then WD has real-time analysis allow by default. Refer to this link: http://answers.microsoft.com/en-us/protect/wiki/protect_defender-protect_start/windows-defender-on-windows-8-introduction-and/f1e00106-6687-4efe-9ec0-ed9f72fabb92

    Check the history of Windows Defender:

    1. Type of user interface modern Windows defender.

    2. Click Windows Defender.

    3. Click the history tab, and then click Details.

    4. Check Date and time if you find any virus.

    Note: The data files that are infected must be cleaned only by removing the file completely, which means that there is a risk of data loss.

    Hope this information is useful. Please feel free to answer in the case where you are facing in the future other problems with Windows.

  • How to pass the windows.old music and itunes

    How can I move itunes music and media from the windows.old folder to the user library where it belongs?  I changed the location of the folder media in itunes (edit/preferences/advanced) but that does not move or copy the music/support.

    Thank you

    You need to go directly to the folder with the music in windows.old and copy the conternts and move to the new folder/location that install you.  Change things in iTunes does not affect the information that were in the Windows.old folder.  If this does not work, then copy the folder to your regular system (not in the Windows.old folder) and try to import and/or by copying the folder into iTunes (or anywhere where the current music is stored if not directly in the library but maybe in the music folder or anywhere where the reference library) to see if you can add it to the library this way.

    I hope this helps.

  • Cannot find the Windows.old folder in my drive and therefore not able to go back to XP to 7.

    I read the article on "How to get back to a previous version of Windows" : http://support.microsoft.com/kb/971760/
    I use Windows 7 Ultimate beta and found this irritating and much lower than XP. He has a lot of bugs and compatibility issues. It crashes every two hours and I lost many of my personal. So, I wanted to go back to my old XP by a clean uninstall of 7. When I inserted the CD at BOOT XP and pressed a button (as guest), he did not. He just started normally.
    Then I inserted within 7, but the gray tab XP installation ! Then I looked far from a solution of Microsoft and went to the link (above). It is said that I need the windows.old file back. But I'm not. I searched all my readers but could not find it. When I typed windows.old in the pavement of research (to the c:\ drive), 4 files are released: file:///D:/Windows/winsxs/x86_microsoft-windows-a..oldertool.resources_31bf3856ad364e35_6.0.6000.16386_en-us_111994699d72a71f/ two other similar to the present and a MUI file.
    Does this mean I do not have the windows.old file and therefore cannot go back to XP. Windows 7 will be released soon and I use the RC version. and so my version will expire soon. WHAT CAN I DO NOW?
    If there isn't a way, I'm sorry to say that I would be looking forward to the next new Google Chrome OS. I love Microsoft Windows for their sincere services. Please help me and do not let me down...

    The only time where you can roll to an earlier version of Windows during installation is when configuring real itself. He has no other choice after installing Windows 7 to return to your previous installation within the OS itself. You have manually will reinstall it.
