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,

When working with the terminal on a MAC OS X system, the "open" command, offers the option "-R" to only show a file or directory in finder but not open the file.

As far as I tried the "start" analogue at the Windows command line, there isn't such an option. How can I accomplish this?

Best Regards

WordPress Tutorial 2: Terminology
WordPress Tutorial 2: Terminology

An important part of learning any new piece of software is understanding the terminology it uses. Thankfully WordPress uses fairly simple names for everything that make it easy to start using the software.

A computer with multiple OS-es my family uses crashed, when you start up it looks like this, cannot load grub:This is how it looks if you try to boot hard drive
If I start the computer with a GParted bootable disk, the file systems are there, and GParted can acccess them:
File systems are there
I can start up this computer fine using an Ubuntu 15 DVD for booting, but I cannot see the hard drive, either file systems.

I would like to make a backup copy of important files from this drive, before experimenting with re-installing grub or a new OS. If I remove the hard drive and connect it through USB to another computer running Fedora Linux, I don't seem to be able to mount the hard drive either as an external drive, because I don't see it as a drive.
Connected as external drive to another computer
How would I mount this on any Ubuntu or Fedora computer so that I would have access to the files?
(Preferably by booting from DVD on this computer.) Thanks.

I have Dell Optiplex 3050 with a 256GB SSD.

I want to create an image of this PC so I can the restore that image onto a few more PCs of the same make & model.

This is the first SSD i've needed to create an image of. I booted up off my Macrium boot USB, opened up Reflect but it doesn't see the SSD.

I'm guessing the SSD won't be seen as it needs a running OS to recognise & read it, is that correct? If it is, how can I create an image of an SSD? Is it possible?

From what I understand, I can create a clone of the disk, but to apply the clone, I have to remove the SSDs from the other PCs, put them in USB caddies and apply the clone image that way.

Does that sound right?

for deployment of windows 10 through system center configuration manager, i read in some articles that MDK is integrated with SCCM

which i think is windows  ADK ? am i correct.

Does SCCM use USMT to do so which is part of MDK?

my question is:

A)if i want to deploy windows image or OS  i can directly do it from SCCM  distribution point or application  so  why use Microsoft deployment kit

B)and if i want to deploy the image to let us say 100 computers, how long it should take through SCCM

Hi,

I plan moving 2 VMs, one 2003 and one XP (Virtual Machine) to a newer ESXi Host.

Because the HAL will change, I will need to reactive the XP / 2003. I assume we can activate the OS ? Anyone have tried an activation recently ?

I'm aware of all the issues running old OS in the network, but it's for an really old apps, internet is blocked and it's backup properly.

Thanks,

I have a server 201 vm residing on a 48 drive SAN that is RAID 10. I am wondering if it is worth configuring the vm OS disk for mirroring? What is everyone's thoughts on doing this? any benefit/drawbacks?

Hello all,

I have a 10 TB GDrive external hard drive that I am trying to use to back up my Mac Pro OS drive. The external drive is formatted as exFAT and is accessible on a Windows 7 machine but not on the Mac Pro regardless of whether using a USB or thunderbolt cable. The drive powers on completely when the cable is connected but I can't see the external drive in Finder or on the Desktop. It also does not come up in the Disc Utility.  

Thanks for your help with the above situation.

Hi Guys
I have been tasked to migrate our SHA-1 Certs to SHA-2 on the CA Servers on our network. However, is there a PowerShell script that can extract SHA-1 information from each of the servers in the estate telling what the certificate is being for?

We have hundreds of servers and want to avoid logging onto each one to try and identify what the certificate is being used for.

I don't want to be migrating the SHA-2 certificate onto the CAs and then everything (Server, OS, Application, Process) breaking because it relies on SHA-1 certs.

Hi all,

I've installed Mac OS Sierra on a VMWare Workstation 12 PC. The install seemed to go ok, and VMWare Tools was installed ok as well.

But when I tried to take a snapshot, VMWare Workstation crashed. And it seems painfully slow, and accessing peripherals like printers and DVD-Drive seems a bit wonky as well.

Are there settings that I'm missing?

Thanks in advance.

Thanks for your time and expertise.
Here's my scenario:  I have an old Server 2008 R2 Enterprise host with four VMs.  Two of the VMs are recent installs and they are running server 2012 R2 Standard.  The two recent installs (the server 2012 R2 Standard vms) need to be activated.  
My question is if I upgrade the host OS to 2008 R2 Datacenter or 2012 R2 Datacenter will this process active the two unlicensed vms, or do I have to purchase licenses for these vms separtely.
Your recommendations and advise are greatly appreciated.

A customer of mine has a malware infested Windows 10 OS and would like me to reload the Win 10 OS so that all applications and data that are currently installed will remain in place.

How can this be done?

I typically configured my spinning hard drives for the OS and Data files as Raid 1. If something happened then I just swapped out the drive and kept working.

When I got the SSD drive for the OS I could only afford the one drive. Now the prices have come down and I was thinking of again using Raid 1, for availability.

Talking with Samsung Tech Support they said that it would work but that they don't recommend it due to the fact that it would shorten the life of the SSD.

Having just had the drive fail and while waiting for the replacement I am thinking of getting my system up with a new SSD and when the replacement ships putting it in a Raid 1 set.

Recommendations?

Thanks,

Steve

My OS is win 10 pro 64 bit and I have a LG MS323 phone which I am trying to setup in iTunes.  I downloaded the latest version, and it did not install the phone.  On researching around I saw that i should try the version 12.1 , so I uninstalled all previous versions of iTunes using the software Revo Uninstaller and then downloaded the 12.1 and installed.  The installation went thru but when I tried to load it I got the error as in the attached file, that there was a library already created in a previous version.  But I thought that the Revo would have deleted 'everything' from iTunes and will not leave any traces any where.
Can the experts please suggest a solution to this problem. Thank u.

I have removed virus infected hard drives from Windows 10 laptops and have connected them as secondary hard drives to another Windows 10 desktop.

 The malware, spyware, adware, and viruses have been removed from these previously infected Win 10 hard drives. Now when these hard drives are scanned there are no threats detected.

Please provide me with the instructions for using AutoRuns.exe to analyze the startup items for these offline Windows 10 hard drives.

 What is the correct syntax for running the SFC command to repair the Windows 10 operating system on these slaved Windows 10 hard drives? I would like to make sure that any additional OS damage or corruption is also repaired.

 When I run the SFC command within a Windows 10 OS I use the following syntax:

 SFC /scannow

 Please provide me with the correct syntax for running the SFC command within Windows 10 for Windows 10 hard drives that are connected as secondary drives.

My OS is win 10 Prof 64 bit and I have the latest version of iTunes.  I also bought a new pc micro usb cable as I think the old was a cheap one and could be the cause.  But with the new cable, the phone which is a LG Model MS323 does not show in iTunes.  My mobile carrier is ultramobile which is a subset of Metro PCS.  
Hope the experts please let me know how to fix this problem.  Thank u

My OS is win 10 Pro 64 bit.  I bought a new Micro USB Charger/Sync cable because my mobile LG phone would no show up on iTunes despite having the latest copy.  Then while researcing one of the solutions was that possibly the drivers are out of date, and this should be the first port of call.
      Is there any free utility for me to scan my pc to see if all my windows 10 drivers are uptodate or not and then go to the particular site and update the driver.  Thank u

We have a server which we have taken out of operation that we would like to install Windows 2016 onto.

The server is the Proliant ML370 G6 and it has a quad port NC375i NIC installed.

We have the OS installed OK but the NIC drivers listed from HP only show upto Windows 2012.

If we try to install those it complains that we are running windows 10 and fails to install.

Does anyone know of a way in which we can get drivers to work with Windows 2016 server, as we would prefer to use this over 2012 if at all possible.

Any suggestions or advice much appreciated.

Many thanks

i am tasked with turning over machines from user to user until they are no longer functional.

i was curious about best practices for switching a machine from 1 user to another.
> is there a way to retain important information from the previous user
> is resetting the machine completely always the best option
> is there anything else that should be done in addition to resetting the machine to make sure it runs at its max potential (besides OS updates )

the majority of machines i work with are windows machines running win 10 pro although i do work on macbooks & imacs as well (some on siearra and some on el capitan)

Hi Guys,

i wanted to purchase an Intel Compute Stick to run a some basics, powerpoint, VNC software, AV. nothing intense!

i wanted it to be windows 10 pro but none of the sticks come pre-installed with it. you can purchase an upgrade through the Windows App store but reading online many people have had issues with this. and also many people have had issues with the stick breaking and then having to re-purchase the licence for the 10 upgrade on the replacement unit due to no product key being given.

so does anyone have hands on experience with upgrading these to 10 pro? are they reliable?

does anyone know an alternative which would also run windows 10 pro out the box?

what do i need the stick for: to plug into a monitor and be used as a display board. need to be able to remotely connect to this on our domain to up-date the slideshow or information being displayed.

all help appreciated,

Peggiegreg
