Want to share my experience since this issue is discussed on the internet I followed the solution I found on YouTube all offered the same solution and none work for me but..
A windows 10 machine hung on startup the window 10 startup circle stopped circling and that's it. The option to login did not shows up.
I restarted it into safe mode as soon I logged in I got the following msg “Microsoft edge can’t open with built in administrator account windows 10”
I searched on YouTube how to fix this error msg, the solutions offered was how to modify the security policy’s for the build in admin. Did not work for me.
What did work was I uninstalled the network drivers (in device manager) did a restart and the system boot was successful.
Seams that since window had an issue with the network driver it gave an error on Microsoft edge. But not sure why it include in the msg the misleading end of being relate to the built in administrator account.
Hope you may find this helpful
I changed my computer's to download Windows Updates Automatically a few months ago, but I've never really trusted it.
Today my mistrust in counting on things to happen automatically was vindicated when I manually opened Windows Update to check manually for updates and promptly got a Windows Update Error 0x80070003
Windows 7 Action Centre, set to warn me if there was a problem with Automatic Updates, reported no problems.
After fixing the problem and getting Windows Updates to work again, (the standard fixes didn't work - a hotfix needed to be installed) it's now installing about ~700MB of critical updates that it just downloaded as I type.
The moral of this post?
Don't trust automatic Windows updates! In fact, don't trust Automatic anything. Use automated updating by all means, I even encourage it to all my clients, but periodically check to ensure that whatever you've set to update automatically is in fact, updating.
According to a google search, the problem I just fixed on my Win 7 Pro 64bit system has been reported occurring on Windows 7, 8, 8.1 and Windows 10 systems during December of 2017 and January of this year. It seems to only happen on certain system configurations.
More key findings from the Spectre and Meltdown patches.
Microsoft found that users running Windows 10 on newer chips (2016-era PCs with Skylake, Kabylake or newer CPUs) should not notice any slowdowns. While there are some single-digit performance penalties, they are reflected in milliseconds.
On Windows 10, Windows 8 or Windows 7 on devices with older chips (2015-era PCs with Haswell or older CPUs), benchmark tests showed more significant penalties and users may actually notice a decrease in performance. On Windows 10, only some users should experience slowdowns, but on older versions of the operating system most users are expected to notice performance issues.
Azure cloud platform had not seen any noticeable performance impact. Some users may experience networking performance impact, but that can be addressed using the Azure Accelerated Networking feature.
Red Hat has also reported seeing measurable performance impact, ranging between 8 and 19 percent, for operations involving highly cached random memory.
Amazon said it had not observed any significant performance impact for the overwhelming majority of EC2 workloads, but some AWS customers have complained about degraded performance after the patches were applied starting with December.
Apple, which started performing tests after releasing updates in December, also said it had not seen any measurable reduction in the performance of macOS and iOS.
Google also claimed to have observed negligible impact…
