The procedure to fix this issue is almost similar to the one described for fixing it on Windows XP, except for one extra step. Here’s the step-by-step process :

1> Click on Start Menu –> Go to Run Command box –> Type regedit –> This opens the registry Editor.

2> Navigate to HKEY_LOCAL_MACHINE\Software\Microsoft\MSLicensing

3> Delete all the keys under MSLicensing : both HardwareID and Store keys and their subkeys. If you are not sure how to delete the key and its subkeys, just rename them as follows : HardwareID to HardwareID-temp and Store to Store-temp.

4> Reboot the system.

5> After rebooting (ensure you are logged in as administrator), click on ‘Start‘ menu–> ‘Programs / All programs‘ –> Accessories

6> Right Click on Remote Desktop Connection and select the option “Run as Administrator“. This will recreate new Keys Hardware ID and Store under MSLicensing.

7> If you had renamed the keys and subkeys instead of deleting them, navigate to HKEY_LOCAL_MACHINE\Software\Microsoft\MSLicensing and you’ll notice the two newly folders created – HardwareID and Store. Delete the old HardwareID-temp and Store-temp and close the registry editor.

This solves the problem and you will be able to connect to remote servers using Remote Desktop Connection.

A. Numerous utilities are available for extracting the content of an
MSI file. For example, you can use Msidb.

However,
another way is to perform an administrative installation, using the /a
switch and specifying a target folder for the extraction. For example:

msiexec /a mm26_enu.msi /qb TARGETDIR=d:\temp\mmextract

These commands assume administrative rights on the PC.

To temporarily disable the PC Speaker beep:
net stop beep

To disable the PC Speaker beep for good (until you undo this setting):
sc config beep start= disabled

So, if you are bothered right now by PC Speaker beeps and want them to go away even after a reboot, run net stop beep and then run sc config beep start= disabled.

The space between start= and disabled is required.

A. As part of a deployment using Microsoft Windows Preinstallation
Environment (WinPE), you might need to partition the disk. The easiest
way to do this is to place into a file the following commands:
select disk 0
clean
create partition primary
select partition 1
assign letter=c:
active
format
exit

Then execute the commands using the Diskpart command with the the /s
parameter, as the following example shows:
diskpart /s partscript.txt
The command creates one partition with all the space; alternatively,
you can replace the “create partition primary” with “create partition
primary size=” (e.g. “create partition primary size=10000″)
to create a 10GB C: drive.

Tip: Locate this XML file and choose the right backup feature
Windows XP’s System Restore feature is an excellent first step for replacing system files Registry entries that were corrupted by a virus or bad driver. It won’t back up and replace user files, such as Favorites, or data files with extensions like .jpg or .doc. Before you use System Restore to replace the existing registry with an old one, for example, you might want to determine exactly which file types System Restore will replace and which it will ignore.
Fortunately, Windows XP stores a file named FileList.xml in which it lists all the extensions System Restore recovers. You can view the list from any Windows XP computer as long as you log in to the PC as a user with access to the system files.

To view the System Restore extension list:
1. Open Windows Explorer and select Tools | Folder Options and select the View tab.
2. Deselect the Hide Protected Operating System Files (Recommend) check box (if selected) and click OK.
3. In the resulting Warning dialog box, click OK, and then click OK to close the Folder Options dialog box.
4. Navigate to %systemroot%\system32\restore (%systemroot% is often C:\Windows) and double-click the file FileList.xml.

The mystery of the missing gigabytes will continue to baffle computer users until hard drive makers get in sync with the rest of the computer world. You’re not missing any gigabytes—it’s just a mix-up in units of measurement.

Disk capacity is measured using decimal kilobytes, megabytes, and gigabytes. In decimal units, 1KB = 1,000 bytes, 1MB = 1,000,000 bytes, and 1GB = 1,000,000,000 bytes. But for file sizes, memory, and just about everything else, we use binary kilobytes, megabytes, and gigabytes. In binary units 1KB = 1,024 bytes, 1MB = 1,048,576 bytes, and 1GB = 1,073,741,824 bytes. Looking at it another way, the decimal values are 103, 106, and 109 bytes, whereas the binary values are 210, 220, and 230 bytes.

To convert your disk’s 160 decimal GB to the units used by the rest of Windows, you have to divide by 1.073741824. The result is about 149GB—close enough to what you calculated. Sorry, there’s no missing 10GB for you to recover!
