How to delete Windows.old after reinstallation or upgrade

How to delete Windows.old?
Windows.old is a folder in partition C: /, which remains behind after a reinstallation of Windows, or upgrade to a higher version of Windows (an upgrade).
When trying to delete Windows.old, we hit the refusal of the system to delete the content Windows.old; Indeed some files are deleted, but most of them remain and they can not be removed under any circumstances.
Deletion does not work because these folders and files, in Windows.old are marked as system files and protected.
To delete Windows.old, we do not need third party software, we only use Disk Cleanup, a Windows utility that users do not really use it.
Its use Disk Cleanup to delete the Windows.old is a very good idea because it is already in PC and also did not delete elsewhere, as do other cleansing programs.
How to delete Windows.old?
1. Right click on the C: drive /
2. properties
3. disk Cleanup
4. After analyzing, click on "Clean up system files"
5. After analyzing, select "Previous Windows installatons"
6. Click OK, and in the "Delete files" dialog box
7. Now be patient and not interrupt the process!

    or if you do and you please a tutorial for those who have licensed Windows,

    • So you can benefit from free 10 Windows, you must have a Windows license 7 or 8.
      If Windows with Windows you bought in the store or if you've bought your Windows means that you will get updates. Dava no, no!
      Windows license can buy from stores with IT products.

      • Marius L. said

        Likely to have lost the license, if you did clean install, rather than upgrade. Haste makes waste!

  5. Normally I would have to go jerky because you have an old video card Radeon HD series 4000 this video but I had no problems, possibly because there were many movements

    Cristi hello I never had problems with 60 fps super seen better luck than ever before are still the hottest

  7. Catalin said

    ptr those who have licensed windosul 7,8 8.1 download or installation kit here and update directly without waiting for the notification of all the best… .and yes it looks bestial at 60 frames.

  8. Catalin said

    … And one more thing, after updating (I honestly downloaded the iso image first and installed the windos 10 from Windows, and after the installation the windos remained activated)… .there is a perfectly legal utility that backs up to the Windows 10 license- advanced tokens manager… same used for Windows 8 or 8.1. Once backed up you can reinstall the boot winder thousands of times… because that utility will activate windos 10 indefinitely… .a good evening.

    The YouTube player says that 720p and 1080p would be at 48 frames, not 60…

  10. Cosmin said

    I also have a problem… today 29.07.2015 when windows 10 was launched I was able to install it exactly after 13 pm on a laptop with windows 8.1, and it went without problems. But, I have another ambiguity… on a PC with windows 7, it gave me a kind of fail, meaning windows tried another (hidden) upgrade and failed. Then I searched on google and found a "forced" update, practically the same thing, it's just the command from cmd. All good and beautiful, I installed it, it works fine, only that in Windows Activation I get something with "connect windows to internet to complete activation" anyway something with internet connection… what could be the problem? or how I could solve it. I want to mention that windows meets the requirements, and it is not pirated, it has a OEM license for life (from windows 7).
    Thanks, Cosmin.

    • Adrian Gudus said

      Perhaps you have a security suite that contains firewall. Stop firewall.

      • Hello,
        Thanks for the reply, but I solved it. I restarted the PC, I went there in the settings to "Activation", I removed the cable from the internet, I waited about 10-15 seconds, then I put it back and it worked. Is it okay how I proceeded? (I didn't see the answer at the time, and this idea came to me).
        Thanks, Cosmin.

  11. I also have a question as an obs that you know everything…
    I also have a Netis wf2419l Wifi and I wanted to upgrade it and after it reached 100% it was restarted and I forgot the ip address and it doesn't emit any signal and I can't access si .and no reset yes from the button… what do you advise me I am waiting for an answer

    You know how I could save license after upgrade from the 8.1 10? I'm thinking of doing a fresh install and it would help to have a license saved somehow.

  13. Hello guys . Yesterday at 13:28 I received an update after which I had the opportunity to upgrade to Wind.10. The installation took about 30 minutes after which I tested the applications and games installed on the old OS (Wind.7 Pro in my case). Following this upgrade, everything worked perfectly, from the installed drivers to the applications used later. First impression… is WoW !!!

  14. * previously used applications… (sorry 🙂)

  15. alberto hub said

    hello I face a dilemma and would like to advise me and me
    I Audio Driver realteck HD Audio is the sound effects a setting called equalization intensity if you tick sounds good but I do not know if it is real to hear the sounds low level of countries want to know will you hold on or off to know if it's normal to be used
    I hope you iteles what I wanted to say in English tells loudness equalizer

    • Hello, Alberto! I have it activated this function for sound to be equal everywhere. I prefer to hear that sound the same (ex. YouTube some videos sound is louder and more slowly to the sound that I want to draw). I hope I have cleared up!

      • alberto said

        thanks for the advice but when you play a game and you hear for example a sound that does not want to be equal such as whispering or steps that should not be heard as the sound of a weapon…

  16. Download this application depending on what OS you want (X 32 or x64). Or, again with this application: Media Creation Tool ISO version can download the Wind.10 or directly on a USB stick. Link to download:

  17. Cristi on YouTube I only option to 1080 48p maximum frames.

  18. Gabriel Costel Irescu said

    Your tutorial is very good, but there is another possibility, there is an option in Windows 10. The steps are as follows. Enter the SYSTEM from the start or from the notification center. Enter the following option in the system, STORAGE, then click on the C: disk (in the partition where the operating system is located) After entering the C: disk on the left will appear a series of data, about music ,… files in the last rows below is also the piece of Windows.old, click on the file to be deleted. That's about what I did. I also had a windows 7 crack with up-to-date updates, and it was activated. It was activated on windows 7 and windows 8.1. Everything is perfect. I want to tell you that I was able to upgrade to an Acer Aspire 1500, the old models, only it has 4 GB Ram and HDD, 320 Hybrid and it moves very fast.

  19. hello, really shows, AQM a question for I did windows update 10 from 8.1 10 now we pro pro, I wanted to know if I format my shawl can use ISO 10 8.1 times must reinstall windows with licenza, thank you

    Thank you

  24. Please help me in trouble. I upgraded to Windows 10 7 Pro PRO from Windows and can not install my webcam on the laptop. In device manager says it's driver installed but has an exclamation mark. Toshiba webcam is installed on a Toshiba Satellite C650 (model made for German and Austrian), unfortunately no longer find any in their archives, or I do not know how it caut.Ce can you recommend to do in this situation, the Windows installation 10 told me that my computer is compatible and has no compatible device.

    • Usually webcams site are to download several webcams: Chicony, Liteon, Philips, etc. Maybe you downloaded anything inappropriate.
      But in the end, if your webcam works fine.

      • Well just does not work, and installed I installed the original driver given by Toshiba.

        • Driver for Windows 8 or 10. If not, try downloading the driver from another site.
          Here are two choices:
          1. Not the right driver for the camera.
          2. There is no driver for Windows 8 or 10.

          • You dreotate driver is to Windws 7. What can I do in this situation, except to wait until a driver do ptr Win 10 because C650 no longer manufactured in a while. It is possible to install a driver Toshiba ptr from another room? I still have a question I always ask the account password from the opening Microsoftinainte Os community. You know how I can get rid of this?

    Unfortunately I have not got rid of the old W., although I respected exactly, instructions in videotutorial;
    I failed in all six attempts in the last six days I hope no connection with the following specifications:
    1. I had 7 licensed W;
    2. I W 10 9 days before the official launch, as a participant in the program Insider;
    3. To-date with updates occurring thereafter;
    4. Samsung EVO SSD 850 125 GB (recently installed on the desktop) works perfectly;
    5. It's a pity W. old to occupy so much space, even or especially if it is on the SSD.
    Please disposal W.old solution.

    Hello Cristi, after a few days win 10 made several up-dateuri and then PC does not stop, just stop hdd but fans continue to work, I searched the net and it seems to be a common problem win8 10 to win and some with a solution but for most of that solution is not good, it may in the future to study the issue and put us here to do a tutorial on how you extinguish it? thanks a lot a good day!

  35. Hi Cristi, I just upgraded to W 10 home premium and everything is going ok. Initially I changed the virtual memory, but I returned to automatic mode (I have 4 giga rams and I resell automatically). We are looking to delete the file from C that can be seen in the "fog" windows bt (ie the one that helped install W10). This is the first question. That is, if I can use that folder to make a DVD with W10?
    My "Windows old" folder has 21 gigs !!!!. Partition C is 100, no bathrooms, but I was amazed by the old W size. I always delete C and format. I admit that I upgraded to W 10 after almost 2 years with W7, but it worked fine and I had no viruses. Can I use disk cleanup to wipe W old quietly? The laptop is a Lenovo Edge think pad from 2011. Thank you!
