Misunderstanding...System Restore does not equal Registry Restore

I am not asking "how to do a system restore" that is something different, by virtue of how its done then what I'm asking...is about doing a full resistry restore from an exported and saved full registry *.reg...and then at the propitious time, importing that same *.reg back into the full registry, just as it was when the exported file was made.

I don't think it can be done, save under safemode using Dos Command. Something I am not willing to attempt at present for fear of losing the whole shebang! But may be someone has a way to share...I'm going to do some more googling on the topic.

The Kosher Solution:

I. Creating a Windows registry back up:

1. Open the Windows Registry Editor.

a. Click Start > Run on the Windows desktop.

b. Type regedit in the Open field.

c. Press Enter or click OK.

The Windows Registry Editor appears.

2. Go to the menu bar and click Registry > Export.

3. Select the directory where the registry backup will be stored (e.g. \temp folder).

4. Enter a file name for the registry backup (e.g. regback1).

5. Check and make sure that the All radio button under Export Range is selected.

6. Click Save.

7. Verify if the backup was created in the specified location in Step 5.

II. Restoring the Windows registry backup:

1. Open the Windows Registry Editor.

a. Click Start > Run on the Windows desktop.

b. Type regedit in the Open field.

c. Press Enter or click OK.

The Windows Registry Editor appears.

2. In the menu bar, click Registry > Import.

3. Select the directory where the registry backup will be imported (e.g. \temp\regback1.reg).

4. Click Open.

5. Restart Windows to begin using the restored registry.

BUT IT DOES NOT WORK THIS WAY...IT WILL QUIT IF ANY OTHER KEYS ARE OPEN...SO HOW TO KILL THOSE KEYS???
