Chrome won't work after Windows 10 update

After a forced update on Windows 10 (to Version 10.0.17134.376) I can't access any site with Google Chrome.

Every time I try to visit a site it times out (ERR_TIMED_OUT).

Microsoft Edge (which suddenly appeared among my desktop icons) appears to work fine.

I've tried

• Restarting the computer


• Reinstalling Google Chrome


• Running the "compatibility problems" dialog on the Chrome application

Nothing has worked.

Any ideas to what I can do?

Answer

The problem

The problem has been discussed on Google Chrome's help forum:

The problem started with the April 2018 Win10 1803 Feature Update and can also happen with fresh Windows installs that use 1803. It is an (unknown) artifact of how Windows is installed or updated. The 1803 update can cause a core Windows identity service (CryptSvc) to loop endlessly and stall connections. -- https://productforums.google.com/forum/#!topic/chrome/s5S1uPI0kMc

Are you affected?

Try the following steps to see if you are affected by this problem:

1. Open Task Manager


2. Go to services


3. Find the CryptSvc service


4. Right click and restart the service

Can you browse sites with Google Chrome now? If so, you are affected and this is only a temporary fix.

Permanent solution

There are a lot of suggestions for solutions around (just google chrome CryptSvc fix)

The simplest fix (that worked for me) came from the Microsoft Forum.

(I have slightly altered the solution for easier understanding.)

1. Run regedit


2. Go to HKEY_CURRENT_USER\Software\Microsoft\SystemCertificates\Root


3. Right click "ProtectedRoots" and click "Permissions"


4. Select your user account and tick "Allow Full Control"


5. Take a backup of Root by right clicking and click export, and save it somewhere


6. Open Task Mananger and stop the "Cryptographic Service"


7. Delete the Software\Microsoft\SystemCertificates\Root registry entry


8. Restart Windows
