Meltdown/Spectre: It's a vulnerability that has existed in all processors for the past 20 years. The fix isn't going to slow down your modern processors. Consumers should be aware of it, but it isn't some crazy imminent threat. There are no known exploits out in the wild at this time.
Windows 10 is already patched, as are most other devices. As always, just make sure you have your devices up-to-date. The patches aren't going to slow down your phone or modern PC. However, there have been issues with a previously released patch for older systems with AMD processors -- but Microsoft has already pulled the patch.
Here is an easy to follow explanation I got from a Cisco engineer:
"Modern processors get some of their performance by trying to guess what you’re going to ask it to do next. It predicts that you’re going to want the CPU to do a task, and gets started on it. So, by the time you ask it to do the work, it’s either already done or close to done.
The flaw is that researchers figured out how anyone can ask the processor what it has guessed you will want to do. This means that an attacker can read things in the computer’s memory that they’re not supposed to have access to. This affects places like Amazon’s EC2 or Microsoft’s Azure where they run virtual servers for many different customers on the same physical hardware."
I would have written an article on this, however, when you get into it, it's quite overwhelming, and it's already been explained so well by another trusted and experienced tech writer, Woody, who is all over the story. So, for more details and clarity, I highly recommend reading the following pieces from Computer World's Woody Leonhard:

Microsoft has released the much-anticipated Timeline feature for it's most recent preview build for Insiders. It should drastically change your workflow for the better, and increase your productivity. And, it's not a crazy complicated new thing to learn.
I have a customized Windows 10 image built using audit mode (using the copyprofile true option in the sysprep file). The image deploys as expected, and every user has the same default profile that I configured on the image. My question is this: How, post deployment, can I now create a local account that can be used to update the default profile on the fly. In other words, if I want to make a change to the default account and have it propagate to all users who log in afterwards, how do I do it?
To give some context here, I have been able to do this on my Windows 7 images (created using the same method), by doing the following:
1. I create a local user. e.g. pcadmin
2. I login as that user to create the home folder/registry settings etc
3. I can then open the registry and go to HKLM\software\microsoft\windows nt\current version\profile list
4. I find the key for my new local account and then update the path to c:\users\default
5. I restart, and when I login as the new local account, I am mapped to c:\users\default. From that point forward, any changes I make in this account (desktop icons, browsers, shortcuts etc), are made to the default account, so every user who logs in afterwards will reap the results of my changes.
Obviously I have tried the above method in Windows 10, but it doesn't seem to work for me despite many attempts. Upon changing the path in the registry, any login attempt automatically signs out immediately. Is there another way to achieve what I want in Windows 10 Professional? Or can anyone verify that this should work?
Thanks for any help you can give!
I would like to create two administrator user profiles, one with complete control and one configured with (at least) two limitations:
1) the inability to move, delete, or otherwise modify executables (or other files, as needed); plan on doing that through making the primary administrator control a given file, and then assigning lesser rights to the secondary administrator.
2) the inability to enter safe mode, modify the registry, or change the time.
I want to give the primary administrator complete rights, so if something happens backup etc. is accessible.
1) First, need to know if it is possible (and won't screw up my system).
2) If it is, can this be done safely, and through group policy?
3) Also, can both users share the same programs, file settings, etc.?
I currrently have Win 10 x64 Home, but am planning to upgrade (the free, fully functional--but nagging) Win 10 Pro to use group policy--it has it, right?
I read that older versions of Windows allowed you to create a "superuser" profile with advanced properties; if I can't do this in Windows 10, would it be advisable to go back to Win 8 (or whatever version supported that feature)?
