I am trying to learn how to make my own os from osdev's wiki, but somewhere there it says that I have to use the grub-mkrescue command. I was doing some research around internet to understand what does that command do and found in the grub official documentation this sentence:
The program grub-mkrescue generates a bootable GRUB rescue image
What is a rescue image?
A rescue image can be used to restore your computer to a previous point in time. grub-mkrescue generates one of these rescue images. They're useful to have so that you have different restore points that you can go back to, or as a backup in case your hard drive goes bad. See this article for more info.

This just started to show up on my Windows10 machine. No browser is open. The down arrow includes a "feedback" option that goes to a .cn website. (I don't understand mandarin!) Right clicking does nothing.
How do I make this go away? Is this machine infected?
This is probably something that got install with another package. They often have a checkbox that says install(some crap) and we just click accept without noticing that small checkbox.
You can probably find out what it is by screening trough your running process. Find and destroy that executable. check your mscongif as well.
and you should probably get an Anti Virus.

what's the matter with it? Windows10
sometimes , I open my computer(laptop),the application's icon will be strange,just like,the picture below.
but once i fresh the desktop them may be normal. if i continue freshing,them may be abnormal instead.
and my source manager will can not open just like the third picture below.
I had already tried to solve this problem but it didn't work.
who knows the problem?
I am so sorry that i don't have 10 reputation point to post image
I think i know what you mean. I think all your desktop icons are a white. It's usually fixed by using CCleaner which can be downloaded here: https://www.piriform.com/ccleaner/download
And you also need around 1 gigabyte of free data on your C:\ drive. If the problem still persists then i recommend you to clean the icon cache:

A friend of mine factory reset her computer on Windows 10, and lost an important document, so I'm wondering if there is a way for her to get it back, any help is useful.
I realize that a factory reset sets the computer back to it's original state of when it was first purchased, but I'm just curious if there are any free or cheap options available, besides going to a recover specialist.
Any advice would be nice - thanks!
Download the free version of Piriform Recuva. It is something I have used before for basic file recovery, and I don't know of a simpler GUI tool for Windows. Simply follow the instructions of this tutorial, or search for a simple video tutorial on YouTube if that is insufficient.
To maximize your chances of recovery reduce the amount of writes to the drive- setting it to read-only for example. Avoiding doing anything else while you attempt to recover the files is critical, newer files may silently destroy whatever is left of the older data. If at all possible you should attempt to boot from a drive or disk that doesn't contain the erased data, but if that is not possible/not something you know how to do then you may still be able to recover the data by booting the computer normally.

I was trying to install a virtual machine on my Mac, and I followed the directions in an article from Digital Trends. I have since found additional resources, which have made me concerned about a step in the original instructions that said to type this into the Mac terminal:
curl -s https://raw.github.com/xdissent/ievms/master/ievms.sh | bash
I initially trusted this code because I thought Digital Trends was safe, but is this code safe?
You're running whatever the contents of that URL are as your current user.
For certain definitions of safe, sure, this is fine, as it won't influence other users of your machine. I'd still take a look at the code in the URL to see if it's doing something you'd approve of doing yourself.
In your specific case, it appears to be a boring install of Microsoft binaries, so if you trust Microsoft to not do anything stupid/dangerous to your machine (I don't), you're likely fine.

Is it 100% safe to move the pagefile.sys file from c: to another drive on Windows Server 2008? We are getting low on C: space and need to move it off, but not if there is any risk. This is a production web server and (other than a quick reboot) downtime is not acceptable, as you can imagine :)
I dont think this is a good place for such questions, its a programming related site,
I can give you a hint that this should be OK, It will even speed up you paging file, some reference below (I was actually reading it recently :) ):
http://lifehacker.com/5426041/understanding-the-windows-pagefile-and-why-you-shouldnt-disable-it
following part:
What you should actually do is move your pagefile to a completely
different physical drive to split up the workload.
but confirm it with some windows admin experts
