XP Lite тебе в помощь - думаю, его там можно удалить как какой-нибудь компонент, типа как "Восстановление системы".

Проверить самому нет возможности - пишу с ноутбука, на котором Windows 7.

Нашел еще несколько способов:

How can I disable EFS on Computers Running Windows XP or Windows Server 2003?

The following procedure will show you how to use Group Policy to disable EFS on computers running Windows XP and Windows Server 2003.

1. Open the GPO that you want to edit. You can use Active Directory Users and Computers or the GPMC to edit the GPO.
2. In the Group Policy Object Editor, expand Computer Configuration, expand Windows Settings, expand Security Settings, expand Public Key Policies, and then click Encrypting File System.
3. Right-click Encrypting File System, and then click Properties.
4. Clear the Allow users to encrypt files using Encrypting File System (EFS) check box, and then click OK.

1. Hold down the Windows key and press R.

2. Type regedit and click OK.

3. Click the plus sign next to HKEY_LOCAL_MACHINE
then SYSTEM
then CurrentControlSet
then Control
then click FileSystem.

5. Right-click the NtfsDisableEncryption entry and click Modify.

6. To disable EFS set the Value data to 1. (To enable EFS again, set the Value data to 0 or delete NftsDisableEncrpytion)

XP - Encrypting File System
I about killed myself trying to find any info about where and why this
was disabled. Found it - finally.

If the machine is a stand-alone machine, then you may have to add the
"EfsConfiguration" key below as stated by MS.

The "LastGoodEfsConfiguration" key seems to be part of the policies
mentioned below. It simply reflects the value set under the policies
key listed at the bottom. I deleted it several times w/o incident (it
just reappeared after reboot).

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\EFS]
"EfsConfiguration"=dword:00000000
"LastGoodEfsConfiguration"=dword:00000000

Change dword value to 1 to disable and 0 to enable.


If there are policies set for your computer (usually part of domain),
then you will need to enable/disable it here:

[HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows
NT\CurrentVersion\EFS]
"EfsConfiguration"=dword:00000000

Change dword value to 1 to disable and 0 to enable.
