Operating systems perform basic tasks, such as recognizing input from the keyboard, sending output to the display screen, keeping track of files and directories on the disk, and controlling peripheral devices such as disk drives and printers. For large systems, the operating system makes sure that different programs and users running at the same time do not interfere with each other. The operating system is also responsible for security, ensuring that unauthorized users do not access the system. Operating systems provide a software platform on top of which other programs, called application programs, can run.

Hi, Experts, I have an .exe application on my computer which have an OS of Windows 10 pro. I need to run this app automatically while restarting my computer. What I meant to say here is that while my computer is waiting for my password to open it, the .exe file should run a head. It won't work while I'm  tried to set on Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run. Is there any other solution to achieve this goal?

I get a black screen when I am trying to install Manjaro 17 from USB onto my Asus tower, G20aj Processor Intel® Core™ i5-4460 CPU @ 3.20GHz, 3201 Mhz, 4 Core(s), 4 Logical Processor(s). . ( had the same issue in Ubuntu, but thought the different loader Manjaro and Arch might make a difference but it hasn’t.)  The problem seems to lie with the Asus video drivers as I can install just fine on my Alienware/Dell and my HP Spectre.
On the Ubuntu side I found posts talking about some commands to run to get around this issue like aspci and quiet splash, etc. I am not sure where to enter commands or how.  

What I have been doing is boot the computer with install USB and go to the Manjaro OS install line press “e” and then go to the line beginning “Linux/boot/vmlinux-$2” at the end of that line place my commands like  acpi_enforce_resources=lax acpi_osi=Linux acpi_osi=’!Windows 2012’ acpi=force pcie_aspm=force
and then hit F10?

Nothing seems to work.  I have been working on the Manjaro forum but have come to a bit of deadend.

A client is saying they have malware on their Mac and want to reinstall the OS.  I've read through this a bit https://support.apple.com/en-us/HT208496 and it doesn't seem to say anything about malware issues.

My question is: Is it better to reinstall Mac OS to clear up malware issues or erase then restore to factory settings?

Are there other things I should be aware of when performing such a task for this macbook?

How do I remoive AD from Server 2012 R2 Esentials server.

I spun up a VM of this OS to figure out how to do it, and while MS support say yes, I am hitting the wall.

Running DCPROMO says - use server manager to remove AD Services
Server Manager > Roles and Features > remove AD - reports cert services needs to be removed
Server Manager > Roles and Features > remove certficate services reports an error, but there isnt any error description.

CompTIA Security+

Learn the essential functions of CompTIA Security+, which establishes the core knowledge required of any cybersecurity role and leads professionals into intermediate-level cybersecurity jobs.

This affects Macs in our environment running OS Sierra, and Microsoft Office 2016.  The users are using Microsoft Word, and in their Word documents they embed images by dragging the image from the desktop and onto the document; they then resize the image and position it where they want, in the document.

The issue is that after saving the document - at some point later, they open the document and find the images are gone, replaced with a empty frame that has a red X, and text that reads: The image part with relationship ID rld8 was not found in the file.

I've searched for possible answers and most Microsoft articles at answers.microsoft.com address a similar issue in Powerpoint and say that it is a problem that affected specific versions of Word for Mac; we're on a later version and the problem persists.

Hi, I recently took over a network with Mac laptops running Mac OS Yosemite, the laptops were part of a Windows Domain had have some administrative lock down settings. We were provided admin privileges so we removed them from the Domain, although we are the computer admins many settings in system preferences are locked out. It seems to me the previous tech support company used some type of lock down policy to prevent even local administrators to make any changes.  Unfortunately  the previous company won't cooperate passing down info other than providing the admin password.

Does anyone know of a way to "unlock" the settings in system preferences?

Windows laptop versus MacBook?

I am a Mac user and love certain features of the Mac. But I also love the incredibly low prices of a Windows Acer laptop.

There is one KEY FEATURE of the Mac that would make the high cost worth me staying on the Mac platform. Key Word Search!

When I try to search on Windows, you better hurry up and wait. When I use Finder, I nearly instantly get a list of files with the search word found in the filename or inside the file (GREP).

I consider this a life-saving feature that lets me find long-lost files, often when I have no idea (or interest in knowing) the physical location of the file.

Can Windows match this awesome power the Mac OS gives me to peruse my files?

Thanks.

See: https://www.kernel.org/doc/Documentation/filesystems/vfs.txt

Dentries live in RAM and are never saved to disc:

A directory is also a file (special file). The contents of a directory consists of:

.           inode-number-current-directory
..          inode-number-parent-directory
filename_1  inode-number-A   
filename_2  inode-number-B
et cetera...

Open in new window


Usually this data is stored in data block(s). I say "usually" because some systems may store this in the directory's inode (< 60 bytes). But usually the data is stored in data block(s). If you make an empty directory, then the contents are:

.           inode-number-current-directory
..          inode-number-parent-directory

Open in new window


Usually you will see something like this:

Blocks: 8

Open in new window


8*512=4096 bytes. So 4096 bytes in the form of data blocks are allocated on disk. A dentry is just a directory entry, so:

filename_1  inode-number-A

Open in new window


So dentries are stored on disk. Then how I have to see this sentence?

Dentries live in RAM and are never saved to disc:

If they would only live in RAM, then you will lose all your dentries if the computer restarts? And why they are not stored on disc/disk? A directory usually just shows 8 blocks, this means that it is stored on disk.

Do I make a mistake here or what's behind it?

I'm having an issue where we cannot get any repair methods to work at all. We had a RAID 5 failure with Disk 1 failing and Disk 0 forcing itself offline. I forced Disk 0 online and then replaced Disk 1 with a new disk and allowed it to rebuild. However, the OS (Windows Server 2012 R2 Datacenter) became corrupted. Anytime I load the OS, I get a Boot Data Configuration error 0x00000f

I tried running all sorts of bcdedit and bcdboot style commands to try to fix the boot files. via cmd line with the recovery DVD. Literally, nothing we tried working. It became a frustrating experience.

We turned to DPM 1801 which has a System State backup. We wanted to restore with that. However the wbadmin start systemstaterecovery didn't work because "its not supported in WinRE environment". If I try wbadmin start sysrecovery, it tells me it can't find the backup. Do I have to blow up the OS, re-install the OS, and then run the restore? Sounds redundant.

I am building an encoding server in Amazon Linux. This is typically build using Mac OS X.

I have one more step, and that is to install "HTTPLiveStreamingTools368.dmg".

What is the simplest method to install an .DMG file typically used on Mac OSX to be installed on Linux?

Thanks for your assistance and suggestions.

I have an early 2008 Mac Pro tower w/4 internal drives configured with El Capitan plus a Bootcamp "Win7 installation" on a separate internal drive.

I want to install a new Win7 partition while maintaining my existing Win7 installation on its separate drive.

Thus, I will end up with 2 BootCamp Win7 partitions, one new and the other old and a bit corrupted.

My purpose is to create a Fresh Win7 installation to which I can easily copy and install some Docs & Applications from my existing over-taxed Win7.

Where do I begin? I assume I need to create a new Bootcamp partition on my Mac OS drive (currently a single partition) or on a separate drive.

Just not sure of the best way to go about that without screwing up either my Mac OS or existing Win7 installation.

Thanks for the help

The device, \Device\Harddisk2\DR2, is not ready for access yet.
 The device, \...\DR4, is not ready for access yet.

No issues with the VMs. Curious what this means and how to resolve. Ive seen volumes are missing to the VMs at a OS level think they are connecting to physical storage. not sure at this point.
