3. By default, standard users cannot install device. When you know certain plug and play devices will be used in your environment, you can preload the device so that users can use the devices. The main task for this exercise is as follows: Install a device into the protected store. Task 1: Install a device into the protected store 1. Log on to LON-CL2 as Adatum\Administrator. 2. Open an elevated command prompt. 3. At the command prompt, type pnputil –a “E:\Labfiles\Mod03\Intellipoint\ipoint\setup64\files \driver\point64\point64.inf”, and then press Enter. 4. Check the list of installed OEM device by typing pnputil –e, and then press Enter. . Install a device 1. Start Computer Management and click the Device Manager node. 2. Expand Keyboards, and update the Standard PS/2 Keyboard driver to the PC/AT Enhanced PS/2 3. Reboot the computer when prompted. Task 2: Uninstall a device driver 1. Log on to LON-CL2 as Adatum\Administrator. 2. Start Computer Management, and click the Device Manager node. 3. Expand Keyboards, uninstall the PC/AT Enhanced PS/2 Keyboard (101/102 Key) driver. 4. Restart the computer when prompted. 5. Log on to LON-CL2 as Adatum\Administrator. 6. Start Computer Management, and click the Device Manager node. 7. Verify you have successfully uninstalled the PC/AT Enhanced PS/2 Keyboard (101/102 Key) driver. 8. Close Computer Management.

Task 1: Identifiying the Fregmentation of a Disk and Ways to Prevent it
The Fregmentation a disk occurs when the Windows I/O Manager saves a file in noncontiguous areas.
This causes the Fregmentation of an availble free space in the disk. This haens due to the following
reason:

1. The number of files increases over a period of time. Therefore. the contiguous file space decreases
   with time.This leads to the Fregmentation of files.
2. The deletion and extension of file result in the Fregmentation of a disk. This forces the I/O Manager
   to save the remainder of the file in a noncontiguous area.
3. Over a period of time. the contiguous free space decreases. This leads to the Fregmentation of a
   newly-stored content.

The Fregmentation of a disk degrades the performance of the Windows system. This is because the read/write
heads are not able to access the noncontiguous blocks quickly

Task 2: Identifying Disk Quotas and Methods for Managing Disk Quotas

A disk quota is a method to limit the amount of space for each user on a volume. This heips in distributing
the disk space for multiple users in a uniform manner. you can ailocate the user based on the role and usage
requirements of the user. The disk quota can also be used to track and restrict the disk consumption. You can
enable quotas on any NTFS-Formatted volume, including local volumes, network volumes, and a removable storage.

The followin methods are used for managing disk quotas:
1. FSUTIL: You canmanage quotas by using the fsutil quota command from the command prompt.
2. Group Policy: You can manage quotas by local or domain-based Group-Policy Object (GPOs). You can
   use the Administrative Templates, System, and Disk Quotas section in (GPOs). The following setting are
   available within GPO tomanage disk quotas:
   . Enable disk quotas.
   . Enforce the disk quota limit.
   . Specify a defauit quota limiy and a warning level.
   . Log an event whan the quota limit is exceeded.
   . Log an event whan the quota warning level is ecvvded.
   . Apply a policy to a removable media device.
3. Disk Properties User interface (UI): You can manage quotas by the Quota tab in properties of a
   selected disk. You can the UI to configure the same settings that are available to the disk Quota
   GPO. Additionally. you can manage.

Task 3: Identifying VHDs and Their Formats

You can present a portion of a hard drive as independentto the Windows operating system by using VHDs.
Windows operation systems can mount VHDs directiy. The Microsoft VHD file format is a virtual hard disk
that is encapsulated in a single file. the VHD can host built-in file systems and supportstandrd
disk operations. Windows supports the following vitual disk formats:
1. VHD: This format supports upto 2 terabytes of storage.
2. VHDX: This format supports virtual disks larger than 2 terabytes, with a maximum limit of 64 terabvtes.

Task 4: Identifying the Tools to Manage a VHD

Windows provides multiple disk management tools. such as the Disk Management console, the Windows PowerShell 3.0
Storege module, and the diskpart command-link tools allow you to create, attach, and detach VHDs.

Task 5: Identifying the Tasks that can be Performed by using the Tools to Manage a VHD

The following tasks can be performed by using the tools to manage a VHD:
1. Create: you can create a new VHD by using the VHD management tools. You can specify the type and size of the VHD.
   It can be initiallzed ans formatted like a normal hard disk. you can also create one or more partition n
   in the VHD. Thereafter. you can format each partition by using any file system, such as NTFS.
2. Attach: you can activate a VHD by attaching the VHD to the host computer. Once the VHD is attached, it
   will appear on the host computer as a local hard disk drive.
3. Detach: you can stop a VHD by detaching the VHD from the host computer. the VHD will not appear in
   the host computer. Once the VHD is detached. it can be copied to other locations.
