So far we have two posts about it: one with <a href=\"https:\/\/me-en.kaspersky.com\/blog\/wannacry-ransomware\/6011\/\" target=\"_blank\" rel=\"noopener noreferrer\">a general overview<\/a> of what happened, and another with <a href=\"https:\/\/me-en.kaspersky.com\/blog\/wannacry-for-b2b\/6024\/\" target=\"_blank\" rel=\"noopener noreferrer\">advice for businesses<\/a>. But it\u2019s become clear that not everyone understands how to patch the Windows vulnerability that is exploited by WannaCry, which allows it to travel from one PC to another. So here, we\u2019ll explain what to do and where to find the necessary patches.<\/p>\n<h2>1. Find out what version of Windows is running on your computer<\/h2>\n<p>First of all, it is important to note that the WannaCry can infect only devices on Windows. If your device runs on macOS, iOS, Android, Linux, or any other operating system, then the malware can\u2019t harm those devices.<\/p>\n<p>Yet, it does pose a serious threat to devices running Windows. But different Windows versions require different patches. So, before installing something, you have to figure out what version of Windows you are running.<\/p>\n<p>To do this:<\/p>\n<ul>\n<li>Press the Windows key + R on your keyboard;<\/li>\n<li>In the \u201cRun\u201d box that appears on your screen, type <i>winver<\/i> and click \u201cOK.\u201d<\/li>\n<\/ul>\n<p>A window showing your Windows version will open.<\/p>\n<h3>2. Install the MS17-010 update that patches the vulnerability in Windows<\/h3>\n<p>Done with finding out the version? Here are the links to the updates for all of the Windows versions for which it has been released. Note that if you aren\u2019t sure if you use 32-bit or 64-bit version of Windows, you can simply download both patches \u2014 one of them will work for you; trying to run the wrong one will bring up an error box but will do no harm.<\/p>\n<ul>\n<li><a href=\"http:\/\/download.windowsupdate.com\/d\/csa\/csa\/secu\/2017\/02\/windowsxp-kb4012598-x86-custom-rus_84397f9eeea668b975c0c2cf9aaf0e2312f50077.exe\" target=\"_blank\" rel=\"nofollow noopener noreferrer\">Windows XP<\/a><\/li>\n<li><a href=\"http:\/\/download.windowsupdate.com\/d\/msdownload\/update\/software\/secu\/2017\/02\/windows6.0-kb4012598-x86_13e9b3d77ba5599764c296075a796c16a85c745c.msu\" target=\"_blank\" rel=\"nofollow noopener noreferrer\">Windows Vista 32-bit<\/a><\/li>\n<li><a href=\"http:\/\/download.windowsupdate.com\/d\/msdownload\/update\/software\/secu\/2017\/02\/windows6.0-kb4012598-x64_6a186ba2b2b98b2144b50f88baf33a5fa53b5d76.msu\" target=\"_blank\" rel=\"nofollow noopener noreferrer\">Windows Vista 64-bit<\/a><\/li>\n<li><a href=\"http:\/\/download.windowsupdate.com\/d\/msdownload\/update\/software\/secu\/2017\/02\/windows6.1-kb4012212-x86_6bb04d3971bb58ae4bac44219e7169812914df3f.msu\" target=\"_blank\" rel=\"nofollow noopener noreferrer\">Windows 7 32-bit<\/a><\/li>\n<li><a href=\"http:\/\/download.windowsupdate.com\/d\/msdownload\/update\/software\/secu\/2017\/02\/windows6.1-kb4012212-x64_2decefaa02e2058dcd965702509a992d8c4e92b3.msu\" target=\"_blank\" rel=\"nofollow noopener noreferrer\">Windows 7 64-bit<\/a><\/li>\n<li><a href=\"https:\/\/download.microsoft.com\/download\/1\/D\/3\/1D38C957-CE2B-45A8-B2B5-A548AFC80E1D\/Windows8-RT-KB4012598-x86-custom.msu\" target=\"_blank\" rel=\"nofollow noopener noreferrer\">Windows 8 32-bit<\/a><\/li>\n<li><a href=\"https:\/\/download.microsoft.com\/download\/D\/7\/1\/D7162EEF-0F67-4AB1-90B9-CF47BCAC568E\/Windows8-RT-KB4012598-x64-custom.msu\" target=\"_blank\" rel=\"nofollow noopener noreferrer\">Windows 8 64-bit<\/a><\/li>\n<li><a href=\"http:\/\/download.windowsupdate.com\/c\/msdownload\/update\/software\/secu\/2017\/02\/windows8.1-kb4012213-x86_e118939b397bc983971c88d9c9ecc8cbec471b05.msu\" target=\"_blank\" rel=\"nofollow noopener noreferrer\">Windows 8.1 32-bit<\/a><\/li>\n<li><a href=\"http:\/\/download.windowsupdate.com\/c\/msdownload\/update\/software\/secu\/2017\/02\/windows8.1-kb4012213-x64_5b24b9ca5a123a844ed793e0f2be974148520349.msu\" target=\"_blank\" rel=\"nofollow noopener noreferrer\">Windows 8.1 64-bit<\/a><\/li>\n<li><a href=\"http:\/\/download.windowsupdate.com\/c\/msdownload\/update\/software\/secu\/2017\/03\/windows10.0-kb4012606-x86_8c19e23de2ff92919d3fac069619e4a8e8d3492e.msu\" target=\"_blank\" rel=\"nofollow noopener noreferrer\">Windows 10 32-bit<\/a><\/li>\n<li><a href=\"http:\/\/download.windowsupdate.com\/c\/msdownload\/update\/software\/secu\/2017\/03\/windows10.0-kb4012606-x64_e805b81ee08c3bb0a8ab2c5ce6be5b35127f8773.msu\" target=\"_blank\" rel=\"nofollow noopener noreferrer\">Windows 10 64-bit<\/a><\/li>\n<li><a href=\"http:\/\/download.windowsupdate.com\/c\/msdownload\/update\/software\/secu\/2017\/03\/windows10.0-kb4013198-x86_f997cfd9b59310d274329250f14502c3b97329d5.msu\" target=\"_blank\" rel=\"nofollow noopener noreferrer\">Windows 10 Version 1511 32-bit<\/a><\/li>\n<li><a href=\"http:\/\/download.windowsupdate.com\/c\/msdownload\/update\/software\/secu\/2017\/03\/windows10.0-kb4013198-x64_7b16621bdc40cb512b7a3a51dd0d30592ab02f08.msu\" target=\"_blank\" rel=\"nofollow noopener noreferrer\">Windows 10 Version 1511 64-bit<\/a><\/li>\n<li><a href=\"http:\/\/download.windowsupdate.com\/c\/msdownload\/update\/software\/secu\/2017\/03\/windows10.0-kb4013429-x86_8b376e3d0bff862d803404902c4191587afbf065.msu\" target=\"_blank\" rel=\"nofollow noopener noreferrer\">Windows 10 Version 1607 32-bit<\/a><\/li>\n<li><a href=\"http:\/\/download.windowsupdate.com\/d\/msdownload\/update\/software\/secu\/2017\/03\/windows10.0-kb4013429-x64_ddc8596f88577ab739cade1d365956a74598e710.msu\" target=\"_blank\" rel=\"nofollow noopener noreferrer\">Windows 10 Version 1607 64-bit<\/a><\/li>\n<\/ul>\n<p>When you click on the corresponding link, your system will download an executable file with an MSU extension.
