This is with Defraggler v. 2.01.239 (latest at the moment), on a fully updated
Windows XP Pro SP 3. No obvious signs of malware (AVG did not report anything,
then I switched to Security Essentials and still nothing). The machine otherwise
performs fine.
When I select Run Once or Run Every Time option from Boot Time Defrag menu, I get a
Problem message box with following contents:
Defraggler was unable to schedule the Boot Time Defrag. Please make
sure you run Defraggler with administrative privileges.
After I click OK (the only button), Defraggler crashes.
The crash is most likely a bug, but I presume there is still a problem with
registry key permissions somewhere to trigger the message.
What registry key(s) does Defraggler access
when scheduling a boot time defrag? I'd need to check their permissions.
