Посмотри в этом файле должен быть список стандартных портов

Там я не нашел, служба обновлений называется wuauserv. погуглил по этой службе, но ничего не нашел. А может блокироваться из-за того что у меня на роутере настоена блокировка по маске сайтов? Где можно посмотреть ссылку по которой windows лезет обновляться?

закрыл все порты кроме http,ftp,pop, smtp

А какие IP адреса у серверов обновлений Microsoft?

А какой протокол используется для загрузки?

Запускаю Центр обновления и свойства сетевого подключения.
В свойствах сетевого подключения трафик мизерный, а занятое пространство диска C увеличивается на гигабайты.

это гугл знает, само собой не ты единственный с таким типом подключения. а откуда уверенность, что windows update вообще работает

Configure the firewall to allow communication for the HTTP and HTTPS ports used by the WSUS server. By default, a WSUS server that is configured for the default Web site uses port 80 for HTTP and port 443 for HTTPS. By default, the WSUS server uses port 8530 for HTTP and port 8531 for HTTPS if it is using the WSUS custom Web site. For more information, see How to Determine the Port Settings Used by WSUS.

Question

We have a secured environment setup and we want to only allow windows updates in that machine. Can you please let me know what ports and IP address range we need to allow.

All replies

If there is a corporate firewall between WSUS and the Internet, you might have to configure that firewall to ensure WSUS can obtain updates. To obtain updates from Microsoft Update, the WSUS server uses port 443 for HTTPS protocol. Although most of corporate firewalls allow this type of traffic, there are some companies that restrict Internet access from the servers due the company’s security policies. if your company restricts access, you need to obtain authorization to allow Internet access from WSUS to the following list of URLs:

• Proposed as answer by Marcin Policht MVP Tuesday, February 25, 2020 11:43 AM

Windows Update requires TCP port 80, 443, and 49152-65535.

The IP address for the Windows Update web site constantly changes and it is not a fixed address. Also, there is no official publication of the IP addresses. We normally advise against defining IP addresses on the firewall for this purpose. Instead, we suggest either allowing all outbound connections to http & https ports or defining the DNS addresses as permitted destinations for traffic via the firewall.

For up-to-date information about the IP’s being used by Windows Update, use the DNS system, as this is the only reliable up to date source of information. If you use DNS, make sure the following destination hosts are specified:

Also check this similar case for a hint, the proposed reply is worthwhile to trying.

Windows Update: FAQ

Note: If you’re looking for Microsoft Office update info, see Install Office updates.

In Windows 10, you decide when and how to get the latest updates to keep your device running smoothly and securely. When you update, you’ll get the latest fixes and security improvements, helping your device run efficiently and stay protected. In most cases, restarting your device completes the update. Make sure your device is plugged in when you know updates will be installed.

If other questions come up when you update Windows 10, here are some other areas that might interest you:

When you only want info about updating Windows 10, you’ll find answers to many of your questions here:

When the Windows 10 May 2020 Update is ready for your device, it will be available to download and install from the Windows Update page in Settings. Choose a time that works best for you to download the update. You’ll then need to restart your device and complete the installation. After that, your device will be running Windows 10, version 2004.

To manually check for the latest recommended updates, select Start > Settings > Update & Security > Windows Update > Windows Update .

To get help updating to the latest version of Windows 10, go to the Microsoft software download page and download the Update Assistant.

Some updates may not be available on all devices at the same time—we’re making sure updates are ready and compatible.

To stay up to date, select Start > Settings > Update & Security > Windows Update > Windows Update , and then select Check for updates.

If a feature update is available for your device, it will appear separately on the Windows Update page. To install it, select Download and install now.

Here are a few things you can try if you’re having trouble installing updates:

Make sure that your device is connected to the internet. Downloading updates requires an internet connection.

If you’re connected the internet, try to install the updates manually. Select Start > Settings > Update & Security > Windows Update > Windows Update , and then view available updates.
Check for updates

Run the Windows Update Troubleshooter. Select Start > Settings > Update & Security > Troubleshoot . Under Get up and running, select Windows Update.

The time required to download updates primarily depends on internet connection speed, network settings, and update size. Make sure your device is plugged in and connected to the internet to download updates faster.

You can’t stop updates entirely—because they help keep your device safe and secure, updates will eventually need to be installed and downloaded, regardless of your update settings. Here’s how to temporarily pause updates from being downloaded and installed. Note that after the pause limit is reached, you’ll need to install the latest updates before you can pause updates again.

In the Windows 10 November 2019 Update (version 1909) or later, or in Windows version 1809 for Pro or Enterprise, select Start > Settings > Update & Security > Windows Update . Then choose one of the following options:

Select Pause updates for 7 days.

Select Advanced options. Then, in the Pause updates section, select the drop-down menu and specify a date for updates to resume.

To finish installing an update, your device will need to restart. Windows will try to restart your device when you’re not using it. If it can’t, you’ll be asked to schedule the restart for a more convenient time. Or, you can schedule anytime by following these steps:

Select Start > Settings > Update & Security > Windows Update > Windows Update .

Select Schedule the restart and choose a time that’s convenient for you.

You can set active hours to make sure automatic restarts for updates only happen when you’re not using your device. Learn about active hours for Windows 10.

Try deleting files you don’t need, uninstalling apps you don’t use, or moving files to another drive like an external USB drive or OneDrive. For more tips on freeing up disk space, see Free up drive space in Windows 10.

We recommend keeping devices like laptops and tablets plugged in when you’re not using them. This way, if updates are installed outside active hours, your device will have enough power to complete the installation. Windows updates don’t consume more battery than other typical system processes.

An update history is available so you can see which updates were installed, and when. You can also use this list to remove specific updates, although we don’t recommend this unless it’s necessary.

Select Start > Settings > Update & Security > Windows Update > Windows Update > View update history .

For more info about what’s included in updates for Windows 10, see Windows 10 update history.

We don’t recommend that you remove any installed updates. However, if you must remove an update, you can do so in update history.

Select Start > Settings > Update & Security > Windows Update > View update history > Uninstall updates.

Select the update you want to remove, then select Uninstall.

Feature updates are typically released twice per year and include new functionality and capabilities as well as potential fixes and security updates. Quality updates are more frequent and mainly include small fixes and security updates. Windows is designed to deliver both kinds of updates to devices through Windows Update.

To double check that your device is up to date, open Settings > Update & Security > Windows Update and see your update status and available updates.

To find which version of Windows you’re running, see Which version of Windows operating system am I running?

Reserved storage is not automatically turned on by Windows in any update scenarios. It is only turned on for new devices with the Windows 10 May 2019 Update (version 1903) or later preinstalled, or devices on which a clean install was performed.

Note: If you’re looking for Microsoft Office update info, see Install Office updates.

The best way to keep Windows 8.1 up to date is to turn on automatic updates. With automatic updates, you don’t have to search for updates online or worry about missing critical fixes or device drivers for your PC. Instead, Windows Update automatically installs important updates as they become available.

To turn on automatic updates:

Open Windows Update by swiping in from the right edge of the screen (or, if you’re using a mouse, pointing to the lower-right corner of the screen and moving the mouse pointer up), select Settings > Change PC settings > Update and recovery > Windows Update. If you want to check for updates manually, select Check now.

Select Choose how updates get installed, and then, under Important updates, select Install updates automatically (recommended).

Under Recommended updates, select Give me recommended updates the same way I receive important updates.

Under Microsoft Update, select Give me updates for other Microsoft products when I update Windows, and then select Apply.
