It is not official recommendation from either Citrix or Microsoft, and is only intended as a starting point for administrators to evaluate in their own staging environment. If deployed correctly, these optimizations can significantly improve the scalability and user-response of Windows 10 virtual desktops delivered using Citrix XenDesktop. Disclaimer This White paper is intended for administrators deploying Windows 10 in a XenDesktop 7.x environment. Many of the examples reference non-persistent environments, but the modifications also apply to persistent desktops. The materials in this document are provided “as is” and Citrix hereby disclaims all express or implied representations. Removing Unnecessary Windows 10 Applications Windows 10 contains many applications after a fresh installation. After installation, Windows 10 Enterprise contains over 50 applications already in my start menu, many of these are the system apps that we want to keep like PowerShell and Command Prompt, but there are many others that are unneeded, and will consume unneeded resources. Look at the Windows 10 list of default apps by running the following PowerShell command: Get-ProvisionedAppXPackage -Online|Select DisplayName www.citrix.com | Technical Note | Windows 10 Optimizations 3 Before creating a master image, the following PowerShell command can be run to cleanup all unnecessary applications. Get-AppxPackage -AllUsers | Remove-AppxPackage Scheduled Task Considerations Many of the scheduled tasks listed below were designed to enhance a persistent Operating System. Many Windows 10 instances in XenDesktop are provisioned on-the-fly and discarded upon log-off, using MCS or PVS. The scheduled tasks below may be removed. Below is a sample PowerShell script that removes all task not named Outlook or GoToMeeting. #Remove all scheduled tasks except task to pin outlook to taskbar #if -notmatch -or does not work here $schedule = New-Object -com Schedule.Service $schedule.connect() $tasks = $schedule.getfolder("\").gettasks(0) foreach ($task in ($tasks | select Name)) { if ($task -notmatch "G2MUpdateTask"){ $task2 = $task if ($task2 -notmatch "outlook"){ SchTasks /Delete /TN $($task2.name) /f } } } Microsoft Customer Experience Program Tasks Description Aggregates and uploads Application Application Telemetry information if opted-in to the Experience \ Appraiser Microsoft Customer Experience www.citrix.com | Technical Note | Windows 10 Optimizations 4 Improvement Program.

  • Attachment D to Adm. Memo No. 004 INSTRUCTIONS FOR
    Attachment D to Adm. Memo No. 004 INSTRUCTIONS FOR FORMATTING A DISKETTE Formatting is the preparation of diskettes for storage of information. There are several different versions of the format command that can be used. The version that you use depends upon the type of diskette and the type of disk drive in which the diskette is being formatted. In order for us to be able to read the Tuition Grant diskettes you send, the diskettes should be properly formatted. Below is a table that identifies the more commonly used diskette types and disk drive specifications. The correct version of the format command will appear in the row for your diskette type and drive type. The format command uses the parameter “d:” to indicate the disk drive designation. For example, your 5 ¼ drive may be the “A:” drive. Instead of typing “FORMAT D:”, replace the drive designation with “A:” and type “FORMAT A:”. To verify that the disks were formatted correctly, perform the CHKDSK command on the newly formatted diskette. The format for the CHKDSK command is “CHKDSK d:”. When the command returns the disk information, compare it to the information in the fourth column of the table that corresponds to your diskette type and disk drive.. If the “total disk space” numbers are the same, the diskette is formatted correctly. DISK TYPE DRIVE TYPE FORMAT COMMAND SPACE INFO. 5 ¼” DSDD DSDD FORMAT d: 362,496 bytes total disk space 5 ¼” DSDD HD FORMAT d: /T:40 /N:9 362,496 bytes total disk space 5 ¼” HD DSDD Cannot be formatted 5 ¼” HD HD FORMAT d: 1,213,952 bytes total disk space 3 ½” DSDD DSDD FORMAT d: 730,112 bytes total disk space 3 ½” DSDD HD FORMAT d: /T:80 /N:9 730,112 bytes total disk space 3 ½” HD DSDD Cannot be formatted 3 ½” HD HD FORMAT d: 1,457,664 bytes total disk space 3 ½” DSHD FORMAT d: 1,457,664 bytes total disk space.

Series Question: Assuming they don't want FAT32, Long Filename support, or Sockets, why should my customer upgrade to the newest ROM-DOS? Answer: Since our first FAT32 and LFN release 4.00.1091, there have been several improvements to the core ROM- DOS kernel. This core code is used primarily for our DOS 6.22 compatible compilations, and then extended in the case of a FAT32 or Long Filename build. The 4.00.1091 release is also a new code base and there will be no further upgrades to the previous DOS 6.22 code. In order to obtain new features, fixes, and support a customer must upgrade to release 4.00.1091 or greater. Along with the performance enhancements for both size and speed, several corrections have been made to the ROM-DOS kernel. These include stack and memory issues, disk access issues, and compatibility with the former market leader in DOS. Most of the ROM-DOS utilities have also been improved for size and speed, along with bug fixes. The major changes happened with the XCOPY, HIMEM, MSCDEX, CHKDSK, FDISK and FORMAT utilities. In the realm of international support, the Euro was added to the keyboard and display driver code. ROM- DOS and PC-DOS 2000 are the only non-GUI operating systems to support the Euro. Finally, new ROM-DOS utilities have been added.

    IRIS TECHNICAL BULLETIN TB-1052 Digital Video Systems Subject: Installing and Running Check Disk on XP Embedded Systems Hardware: TotalVision-TS Software: IRIS DVS XPe Ver. 11.04 and Earlier (Including FX and non-FX Units) Release Date: 12/22/08 SUMMARY IRIS DVS units initially produced prior to January 1, 2009 may not have complete support for running chkdsk.exe even though the chkdsk.exe file exist in the Windows/System32 directory. This Technical Bulletin describes how to install and run the Check Disk (ChkDsk) utility to minimize file corruption problems and potential RAW Disk failures. INSTALLING SOFTWARE Several additional files are needed to be installed on the DVS hard drive. You can get a copy of these files at the IRIS Web Service Site www.SecurityTexas.com/service. Download the “Check Disk Upgrade” package and follow the instructions in the ReadMe file of that zip file on how to upgrade the files on the DVS. Once the files are copied to the hard drive, highlight the file “EVENTVWR.MSC” and then select “File- >Pin to Start Menu” to provide an easy way to access the Event Viewer. After the required software has been installed run Windows File Explorer and select the C:\BankIRIS_NT directory. Double-click on the AUTOCHECK.REG file. Answer YES in response to the two prompts to update the registry. Expert Mode: To verify that the registry changes were done you can select “Start->Run” and type in “RegEdit.exe” to run the Registry Editor. Select the key “HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Sesion Manager”. Select the key "BootExecute".

  • External Commands
    5/22/2018 External commands External commands Previous | Content | Next External commands are known as Disk residence commands. Because they can be store with DOS directory or any disk which is used for getting these commands. Theses commands help to perform some specific task. These are stored in a secondary storage device. Some important external commands are given below- MORE MOVE FIND DOSKEY MEM FC DISKCOPY FORMAT SYS CHKDSK ATTRIB XCOPY SORT LABEL 1. MORE:-Using TYPE command we can see the content of any file. But if length of file is greater than 25 lines then remaining lines will scroll up. To overcome through this problem we uses MORE command. Using this command we can pause the display after each 25 lines. Syntax:- C:\> TYPE <File name> | MORE C:\> TYPE ROSE.TXT | MORE or C: \> DIR | MORE 2. MEM:-This command displays free and used amount of memory in the computer. Syntax:- C:\> MEM the computer will display the amount of memory. 3. SYS:- This command is used for copy system files to any disk. The disk having system files are known as Bootable Disk, which are used for booting the computer. Syntax:- C:\> SYS [Drive name] C:\> SYS A: System files transferred This command will transfer the three main system files COMMAND.COM, IO.SYS, MSDOS.SYS to the floppy disk. 4. XCOPY:- When we need to copy a directory instant of a file from one location to another the we uses xcopy command. This command is much faster than copy command. Syntax:- C:\> XCOPY < Source dirname > <Target dirname> C:\> XCOPY TC TURBOC 5.

  • Repair Your Computer in Windows Vista Or 7
    Repair your computer in Windows Vista or 7 How to use System Recovery Options for repairing Windows Vista or 7 installations Visiting www.winhelp.us adds cookies (the non-edible ones) to your device. More non-scary details are in Privacy Policy. Stay safe! When Windows is not able to start even in Safe Mode, then most probably there are some errors or missing files on your hard disk that prevent Windows Vista or 7 from starting correctly. Repair Your Computer is a set of tools for recovering from Windows such errors and it is available on Windows installation DVD. Windows 7 users can also create a System Repair Disc, or borrow one from friends - as long as the hardware architecture (32-bit/x86 or 64-bit/x64) matches. Here are some troubleshooting steps to try before using Repair Your Computer: Last Known Good Configuration often solves booting and stability problems after installing software, drivers, or messing with Registry entries. Always boot to Safe Mode at least once - this often repairs corrupted file system and essential system files. If Windows is able to boot, use System File Checker and icacls.exe to repair corrupted system files. While Windows is running, use free WhoCrashed for determining BSOD (Blue Screen Of Death) causes. Also, Reliability Monitor might reveal faulty drivers or software. System Restore can help reverting back to a state when your computer was running normally. Windows 7 user might be able to launch Repair Your Computer or Startup Repair from a hidden system partition. The two options are described later in this article.

  • Speed up Your PC: Automate Your Computer Maintenance Schedule (Provide by Microsoft)
    Speed up your PC: Automate your computer maintenance schedule (Provide by Microsoft) Most people do one of the following when their computer begins to slow down (besides get angry): Speed up their computer by buying more memory. 1. Try to tweak their computer's settings. 2. Give up. They figure that their computer is old, there's nothing else they can do, and it's probably time to buy a new computer. All these solutions can help increase PC speed. However, what's to keep your newly blazing PC from slowing down again after a couple months or years? A badly fragmented hard drive will bring even a top- of-the-line new computer to a grinding halt. One option is to create a preventive PC maintenance plan—a computer maintenance schedule that's easy to set up and put in motion so you never have to think about it again. The plan outlined in this paper uses tools that are built in to your Windows operating system, including Disk Defragmenter, so they can be run free of charge as often as you like. The following sections provide information on how to automate a maintenance schedule to help keep your PC running smoothly. These procedures differ from version to version, but overall you'll find these tasks work for Windows 7, Windows Vista, and Windows XP. Create a preventive maintenance plan for your computer When people notice their computer's performance slowing, the most common reason is the hard disk. Your computer's hard disk is a non-removable area that holds all the information available from your computer.

  • SEARCH PATH – How It’S Used
    SEARCH PATH – How it’s used: Before discussing the concept of a SEARCH PATH, there are a few things you must be familiar with. (Information on the PATH command is provided at the end of this document.) Command Processor The cmd.exe file is the command processor or command interpreter. It gets loaded into RAM when you start the computer. Its job is to process or interpret the information that you provide to it. For example, if you type a command at the command line; it reads the command and decides what to do with it. If you click on an icon on the desktop; it’s the command processor that handles your request. Some commands are built-in to the cmd.exe file. (Note: In Windows98 – the command interpreter file is command.com.) Internal Commands Commands that are loaded into memory when the computer is started are internal commands. They are always stored in memory and therefore easily accessible by the operating system. Internal commands are part of the cmd.exe (xp)/command.com (98) file. When executing an internal command, the operating system finds and executes the command in memory. External Commands Commands that are not part of the command interpreter file and that are not loaded into memory when the computer is booted are referred to as External Commands. They are physical files that can be found on the hard drive. When executing an external command, the operating system must go to the hard drive, find the command, load it into memory and then execute it. SEARCH PATH When executing any command from the command line the operating system must find the command before it can be executed.
