1.Adjust the Internet Bandwidth Settings:

Since windows 10, with the aid of  using default ,reserves 20% of the Internet bandwidth for the system applications and its operating system, you can’t browse or surf on the Internet with 100% Internet connection. This solution speeds up the dropping Internet speed by trimming down the bandwidth which is reserved for Windows 10 and system applications. Follow the step-by-step guide to tackle slow Internet after Windows 10 Update.

Step 1. Press Windows shortcut keys Windows + R to open Run dialog box.

Step 2. Type gpedit.msc and then hit OK.

Step 3. Give permissions. A pop-up window will open with title of Group Policy.

Step 4. Click on Computer Configuration on the right side of the window.

Step 5. Navigate to: Administrative Templates >Network >Qos Packet Scheduler >Limit reservable bandwidth.

Step 6. Click on Enable.

Step 7. Change the Value from 20 to 0.

Step 8. Apply and after which click OK.

2.Uninstall

The maximum apparent solution to this problem is uninstalling the update itself. Since the new Windows 10 update is causing trouble, the easiest thing to do is to uninstall it and hold off updating your operating system until a newer update is released. Once uninstalled, Windows users have reported that the issues they are facing decease to exist.

        The procedure of uninstalling a Windows 10 update is pretty simple. Open Settings then click Update & Security. A window will appear from which you should choose Windows Update and then View update history. Select Uninstall Updates. You have successfully uninstalled the present update that was downloaded and it should, hopefully, fix your internet problem.

3. Disable Updates

Windows has an option called ‘Peer to Peer Updates’ which can be useful for those who are too busy to download Updates and keep their system up-to-date. However, for some, it can wreak havoc. Since these updates download automatically without informing the user, they use 90 percent of the internet bandwidth causing your internet connection to be slow during this Windows 10 update.

           The apparent solution is turning these Peer to Peer Updates off by doing the following. Go to Settings and then Update & Security. Choose the first option called ‘Windows Update’. Click Advanced Options. Select Delivery Optimization. Now, turn Allow Downloads from other PC(s) OFF. This will disable future automatic updates.

4.Update Your Network Drivers:

Some unexpected driver errors may happen when upgrade to new Windows OS. Outdated, missing or incorrect network drivers may result in limiting internet speed. To rule out that possibility, you might as well turn to a professional driver updater utility tool, like Driver Talent, which is able to match the compatible drivers for your computer and download them automatically within two minutes. All the drivers are collected from the official source (original manufacturers and Microsoft) and they are safe and well tested.

5. Disable the firewall:

Windows 10 has an excellent feature which is a built-in firewall. Firewalls are integral for the security of your malware, however, sometimes, firewalls can slow down your Internet speeds and can be the culprit of limiting your bandwidth.

           Many people criticize this option, but it seems to work for multiple users. Windows 10 has excellent features; it is a built-in firewall. A firewall is an indispensable part of malware security. However, sometimes a firewall may slow down the Internet speed and may be the culprit in limiting bandwidth. You can test the theory by disabling the firewall, and if it speeds up, you only need to switch to a third-party firewall instead of the built-in Windows 10 firewall.
