You can reinstall Windows from scratch using the sản phẩm key that came with your PC, but you’ll have to lớn find installation media yourself. Microsoft offers free ISO files for downloading; you just have lớn know where to lớn look.
There are a few ways to vày this, but they’re all on the straight & narrow–you won’t have khổng lồ visit a shady BitTorrent site to lớn download ISOs that may be filled with malware. Instead, you get official installation truyền thông straight from Microsoft.
NOTE: Depending on the OEM version of Windows that you are running, you might run into an issue using the OEM key with a retail version of Windows. If it won’t activate, you can always install và then hotline Microsoft to get them to straighten it out and allow your copy to activate. The most important thing is that you have a valid license key.
Download the Windows 10 or 8.1 ISO Using the truyền thông media Creation Tool
If you’ve got access khổng lồ a Windows machine, the official method for downloading ISOs for Windows 8.1 and 10 is the truyền thông Creation Tool. The process for using the tool is largely the same for both versions of Windows, so we’ll be using the Windows 10 truyền thông media Creation Tool for our example. We’ll just note where anything differs.
RELATED: How khổng lồ Find Your Lost Windows or Office hàng hóa Keys
One caveat you should be aware of up front is that you can no longer tải về an ISO for Windows 8–just 8.1. And the product keys are different for Windows 8 và 8.1, so if you have a Windows 8 sản phẩm key, you can’t just use it to install Windows 8.1. Instead, you’ll have to lớn install Windows 8, then do a free upgrade lớn 8.1. After you vì the upgrade, Windows will assign the new product key khổng lồ the installation. You can find that hàng hóa key in a number of different ways và save it for the future. After that, you should be able to vì chưng a clean installation of Windows 8.1 using the new sản phẩm key and won’t have to worry about installing Windows 8 first & going the upgrade route.
AdvertisementStart by downloading either the Windows 10 media Creation Tool or the Windows 8.1 truyền thông media Creation Tool. Once the file has downloaded, just double-click it to start the tool & then click “Yes” to lớn give it permission to lớn make changes khổng lồ your PC. When the tool starts, click “Accept” to accept the license terms. Note that the Windows 8.1 version of the tool does not ask you khổng lồ accept license terms.
(If you don’t want khổng lồ use the media Creation Tool and just want to tải về an ISO tệp tin directly, just change your browser’s user agent to lớn a non-Windows browser lượt thích Apple Safari on máy tính bảng ipad while you’re viewing the download page. Microsoft will offer you a direct tải về of the Windows 10 or Windows 8.1 ISO tệp tin instead of the standard media Creation Tool, which only runs on Windows.)

When the tool asks what you want to lớn do, select “Create installation truyền thông media for another PC” and then click “Next.” The Windows 8.1 version of the tool also does not provide this option; it just defaults to lớn creating installation truyền thông for another PC (which is what we want).

The tool will suggest a language, edition, & architecture for Windows based on information about the PC on which the tool is running. If you’re going lớn use the installation truyền thông media on that PC, go ahead & just click “Next.” If you’re planning to install it on a different PC, clear the “Use recommended options for this PC” check box, select options that are more appropriate for the license you have, and then click “Next.” Note that if you’re using the 8.1 version of the tool, you actually start with this screen. The tool also won’t recommend options; you have to select them yourself.
Remember, your license will only work with the correct version of Windows–if your license is for 64-bit Windows 10 Pro, you can’t install 32-bit Windows 10 home with it, so ensure your selections here match what’s listed on your product key.

Next, select whether you want the tool to create a bootable USB flash drive with the installation media, or just create an ISO tệp tin that you can use or burn lớn a DVD later. We’re going with the ISO tệp tin in this example, but the process is much the same either way. If you go with the USB option, you’ll need to lớn provide a USB drive with at least 3 GB of space. Also, the USB drive will be formatted during the process, so make sure there’s nothing on it you need. Select the option you want and then click “Next.”
Choose a place khổng lồ save the finished ISO tệp tin (or point the tool toward the right USB drive if that’s the option you chose).

Download the Windows 7 SP1 ISO Directly From Microsoft’s Website
Microsoft makes the Windows 7 SP1 ISO available for direct download through their site. The only catch is that you’ll need a valid product key in order to tải về the file–and OEM keys (like the one that came on a sticker under your laptop) won’t work. If that’s you, proceed to lớn the next section.
If you vày have a valid retail key, head lớn the Windows 7 download page, enter your product key, và click “Verify” khổng lồ start the tải về process.
After your hàng hóa key is verified, select the hàng hóa language you want to download and then click “Confirm.”
Next, choose whether you want the 32-bit or 64-bit version of Windows 7. When you click whichever version you want, the tải về will begin. Note that download links generated by the site are only valid for 24 hours. Of course, you could always come back và walk through the verification & selection process again to lớn generate new links.
After downloading the ISO file, you can burn it to a DVD by right-clicking it in Windows Explorer và selecting “Burn disc image” khổng lồ burn it to lớn a disc. If you want khổng lồ install Windows 7 from a USB drive, the best way is to use the Windows 7 USB/DVD download Tool khổng lồ put that ISO file onto a USB drive.
RELATED: How to Update Windows 7 All at Once with Microsoft"s Convenience Rollup
The downloaded ISO you’ll get from Microsoft includes Windows 7 with Service Pack 1. When you install Windows 7, you can avoid the hassle of downloading và installing the hundreds of updates that came out after SP1 by installing the Windows 7 SP1 Convenience Rollup. Even better, why not take a little extra time & slipstream the Convenience Rollup right into your Windows 7 ISO? That way, whenever you install Windows 7 in the future, you’ll have one ISO with all the updates (at least up through May 2016) already included.
Download Any Windows or Office ISO Using a không tính phí Third-Party Tool
Microsoft used to lớn make all these ISOs available through a site called Digital River, but it doesn’t anymore. Instead, they’re stored on its TechBench site. The ISOs can be hard to lớn find, though, and for versions of Windows other than the most current, the site tries really hard to push you into using the truyền thông Creation Tool instead. Enter the Microsoft Windows & Office ISO download Tool. This không lấy phí utility provides a simple interface that lets you select the version of Windows you want, then downloads an ISO for that version straight from Microsoft’s tải về servers. This includes various builds of the Windows 10 Insider Preview. You can also use the tool to download ISOs for certain versions of Microsoft Office.

After you select the edition you want to download, click “Confirm.”
Next, use the drop-down thực đơn that appears lớn choose the sản phẩm language you want to download and then click the “Confirm” button under the language drop-down menu.
