Operating Systems





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.

What is the best/recommended way to partition a laptop for Windows 10 pro?  I was just going to create 1 big partition for the sake of simplicity.  Since it is not a server, and just a production laptop, and can be re-imaged,  I am not concerned too much with separating user data/ OS system files between partitions.  I am just curious as to what is the "official" recommended best practice.

How to restore a file in C:\Windows\System32 folder?

"ddkfglmon.dll"  file in "C:\Windows\System32" folder got corrupted. How to fix this?

I have 2 database files on a Windows 2008R2 server that I am unable to delete/rename/move/copy
They are database files ( primary data file and transaction log file) that are replaced each night from a fresh database backup.

This process has been operating successfully, nightly, for years, managed by a job scheduler. All of a sudden the OS is denying the scheduler (and me) access at the file system level. I am able to move/copy/rename/delete other files in the same folder. I am the domain administrator & server administrator.

I have detached the files from SQL server and dropped the database. I have taken ownership of the folder and each of the files, but the response when I try to delete them is that the OS continues to want permission from <me> to allow <me> to delete the files(s), same for both (see the pic). There is adequate space on the volume to carry out all these tasks normally.

I suspect, there may have been contention, around midnight, when the hosting provider does system-wide backups of VMs, which has altered the attributes of the files somehow.

I would appreciate your insight into this strange issue. Thanks in advance.
Cisco IP Phone 7941 still trying to upgrade.

Physically took phone to TFTP Server and uploaded current OS software to the phone.

Everthing in Call Manager looks good.

Cleared port security on the switch.

Phone daisy chained to PC.

PC has good Internet/Network connectivity.
Running Windows 10 Home (up to date) 64bit OS. Recently purchased/installed Paperport 14. Initially running fine. Now Paperport will not load. When I start the program, the Paperport screen appears for a few seconds then closes. The program will not start. I have reinstalled after doing a thorough uninstall, I have also tried many solutions suggested but with no success. Assistance would be appreciated.
I have recently installed Hyper-V Server 2016 on a Dell Poweredge T640.
This was on a new machine, with no other OS etc installed. I used an ISO burned to a DVD to install.
This is my first time working with Hyper-V.

The installation seemed to work fine. After installation, I used the sconfig utility to set up the network.
I have used a static IP address and the correct gateway & subnet mask settings. However, I can't ping anything from the server (nor can I ping the server from anywhere else).
I have disabled the firewall - using netsh advfirewall set allprofiles state off - on the Hyper-V Server installation.
I have enabled ping in sconfig under Configure Remote Management

I have tested the physical LAN cable by plugging another computer into it - it works fine.

I haven't proceeded with any VM installation as I thought I should get this sorted out first. Am I missing something? Shouldn't I be able to ping my gateway at this stage? I have read about Virtual Switches, but I shouldn't need one to ping my gateway, should I?

Thanks in advance for any help!

*** I forgot to mention:

When I use Network Settings in the Sconfig program, my adapter is listed as: Remote NDIS Compatible Device. Is this the problem?

Hi Team, Any idea please about the issue Outlook can't dowload the adresse Book ( online and offline ),

This is actually the first time I've encountered not being able to burn a duplicate of an OS DVD.I have our original from Dell OS DVD for Windows Server 2016 and I want to burn a copy of it, to leave with the server at our datacenter.  I couldn't, because the blank DVD's I have are 4.85GB, but the OS DVD from Dell has 7.53GB data. How'd they do that and how can I burn a spare copy of it?
I need to install a hyperv VM.  The OS has been copied to a folder on the host server. It is not an ISO image. I can't see how to install the OS on a VM using this folder.

I have a laptop with a local account. I changed the name of the local user account from user_name to firstname_lastname and that was all fine.

When I re-started, the new username came up as the login name.

However, I noticed that when I sent a print job, the print job is  listed as the older user_name not the new one.

Also, if I do ctrl + alt + del to change the password, it says "change password for user_name" not the new firstname_lastname

It seems like the only changes have been superficial, but underneath, the account settings have remained as the old user account details on the laptop.

What do I have to do to make sure that the account name change is reflected right the way through the OS?

Many thanks, experts, in advance for advice.

I would like to get a file sharing web app (running as a Docker container) operating called 'YouTransfer'. It fits what we need as a firm for a simple drag and drop document sharer with clients over the web (from our own private network) instead of large attachments being emailed. Basic details of the product are here, alond with the most basic setup instructions: http://www.youtransfer.io/

I've setup VMware's Photon OS, and as far as I can see I have got the YouTransfer container running within the Docker container environment. The bit I'm stumped on is setting up the folder locations for where the files are stored. This is probably my ignorance in the syntax for detailing paths under a Linux OS, but the specific part I don't get I've emboldened below (and tried everything I can think of to get it working):

docker run -d
-v [path_to_upload_folder]:/opt/youtransfer/uploads
-v [path_to_config_folder]:/opt/youtransfer/config

-p 80:5000

I would hope this is a simple one that someone can help me with!

Many thanks :-)
I believe Windows latest update caused sleep mode to reboot the computer.  I'm on OS Build 17134.48 which introduces "task view" among other things.  Has anyone see this issue?  Also, I'm trying to revert back using a Windows recovery point.  This never shows more than one recovery point.  How do I enable more or older recovery points?  Also, remind me how to uninstall this new Windows feature update.
Is there a way to wipe a Macbook clean without removing the OS or is that not a concern...that is, can you simply download an OS for free?  Basically I want to get a Macbook ready for a new user.
Failure with TimeMachine backups. OS Problem?

I had an external disk fail to complete the Time Machine backup with no error message, that I can find. I eventually started afresh using Disk Utility. BUT it still failed!

On another front, I have been told I should re-install the underlying OS on my machine, which I am afraid to do without a current backup!

I do use Cloud based Carbonite, but do not feel safe until I have a hard external backup disk.

The reason I was advised to re-install my OS was that while using Finder, incrementing through my pictures, sometimes the cursor jumps to the end of the list. I did try some small instruction on Mac start-up, if I recall, that involved holding down certain keys.

There was a second instruction, but I sadly can on longer find that post.

So, the last suggestion was to re-install the underlying OS. And it seems I am there right now.

Can anyone suggest a nest step for me?

I can not make a current backup of my machine.

Hi Team,

We use USB Buffalo DVD drives in our environment on our Wyse THIN OS 3040 devices. We also installed latest driver on citrix servers, still when we try to connect to citrix session it showing an error in device manager as STATUS _DEVICE_POWER_FAILURE(This device cannot start. Code10). Tried installing latest drivers but still problem remains same.

Is there something i am missing, or any other driver need to be installed? Can someone help me here.

Thanks in advance, your help is much appreciated.
Windows 10 hangs at blue cursor circle. At first, I knew this to be the 1803 update, and did a system restore and shut off all pending updates. However, now anything that installs updates (Adobe, autodesk, etc) gives me the blue hanging circle of death on a black screen. How can I fix this permanently?

I have tried start up repair, installed new Windows from scratch. Nothing seems to fix this issue.

SOMETIMES, if I restart the PC while pressing Shift+F8, it boots normally.

what are all the ways to find pdf files

I am asking someone to search their computer(s) for me to find pdf files
This was setup in the past but the person that set it up is no longer with us and since we have upgraded the OS  to 2012 R2 and it was setup on 2003 TS. We got rid of the 32003 and added 2 new terminal servers with 2012 R2

We need to setup the following for users,,,,, Multiple users that log into one just one account and from that account they have access to their emails through a drop down tag, the dropdown has all of their names on it. When they choose their name it will pop up and ask them for a password

So basically we need an icon setup on the terminal server so that once the users login with the same single account, they can then click on the mail icon and see there name and select it to and have it prompt them for their password to their email account in exchange.

Does anyone know the steps on how we can set this up?

We have ESXi 5.5 on which I want to automate the deployment of an OS (W10), I created a VM which should boot from a DVD automatically.
It does that, but not before I do 2 manual actions (see screenshot below). How do I configure the VM to do this automatically?
This worked fine with normal BIOS but since I have set it to EFI, it does not work anymore.

Note: first time it should boot from DVD, but only first time (since after that it should load the OS which is being installed):

Good day-
I have an Ntfs volume from a failed server 2003 (not a typo). The volume was RAID1 and a member file server.

Ntfs permissions are keeping me from accessing previous versions - although I can see the previous versions thru explorer.

Any tools you can think of or am I dreaming?
can an installed .exe file on windows os see all my key strokes
I have a custom made .exe file that appears to me to run correctly
but may have additional secret permissions

by installing any program

Best Solution for Upgrading Windows 7 (Of all different versions) to Windows 10 Education.

Unfortunately we don't have a server were we can remotely connect to do have an image pushed down so I think we are just gunna have to go to each device and install Windows 10 manually that way.

But I wanted to reach out to you all and see if there was a better solution. Work smarter not harder!

Our goals are to: Upgrade Windows 7 (Of all different versions) to Windows 10 Education. With no data loss. We do have a way for users to back up their documents but that doesn't stop them from saving stuff to the desktop.

We would also like a custom image where the license key is already in the image. (Not sure how to do that. We do have a volume licensing agreement so one key can be used on X amount of devices)

And lastly is there a way to have certain programs pre-installed already like Microsoft Office 2016 in the image or no?

Thanks so much for taking the time to read all this.
What are the steps to directly upgrade Windows 8.1 to Windows 10 so that all programs, user accounts, and customizations will remain in place after the upgrade to Windows 10 completes?

Is this as easy as downloading the Windows 10 ISO file into Windows 8.1 and then running the Windows 10 setup file within the Windows 8.1 OS and following the prompts to upgrade?
Every time i capture a new image via Windows Deployment Services it asks me for what Administrator password will be set during deployment.
After the image is uploaded to MyImageGroup, i then export it as a custom image and import it into Deployment Workbench as an operating system and then set up a task sequence.
If I look at the properties of the task sequence and click on edit unattend.xml from the OS info tab, the password is set correctly.
I have confirmed this by opening the file from d:\deployment share\control\1030\unattend.xml
When i deploy the image, and reboot the PC after deployment, the local Administrator account is set to a password I used to use a long time ago and not what I set during capture.
Where else would it be pulling the old password in from?
I do update the deployment share each time I add / amend something
Hi - I just formatted the hard disk and reinstalled MAC OS High Sierra for the purpose of setting up Bootcamp.
