Important This section, method, or task contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs. For more information about how to back up and restore the registry, click the following article number to view the article in the Microsoft Knowledge Base:

1. Determine whether the required entry is located in the Windows registry. To do this, follow these steps:
1. Click Start, click Run, type regedit.exe, and then click OK.
2. In Registry Editor, locate and then click the following registry key:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\CONTROL\CLASS\{4D36E967-E325-11CE-BFC1-08002BE10318}
3. In the right pane, locate UpperFilters, and then make sure that the Data value is set to PartMgr.
4. If this entry does not exist, exit Registry Editor, and then go to step 2. If the entry does exist, exit Registry Editor.

2. Click Start, click Run, type cmd.exe, and then click OK.
3. At the command prompt, type the following text on one line, and then press ENTER:
reg add HKEY_LOCAL_MACHINE\SYSTEM\CURRENTCONTROLSET\CONTROL\CLASS\{4D36E967-E325-11CE-BFC1-08002BE10318} /v UPPERFILTERS /t REG_MULTI_SZ /d PartMgr /f
You receive the following message in the Command Prompt window:
The Operation Completed successfully
4. Restart the computer.

In my case I did not have the correct registry entry and had to follow Step 2. Luckily it worked.

 

Pete, does that mean my beta version will be inoperative after that date?
