HP is paying £40,000 for details of 100,000 of its own customers to stop them being circulated elsewhere.
The supplier is paying the money to the court handling the assets of the bankrupt Interex independent HP user group.
Interex, which had 100,000 members, went into liquidation earlier this year with debts of £2.5m after cancelling its annual HP World user conference in the US.

Its membership list was seen as a valuable commercial asset that could be used to raise funds for Interex creditors, but former Interex members were angered that their details would be disclosed to third parties.
A bidding war for the membership database started after a reseller of refurbished HP kit made an offer for the list. The database is also believed to contain the IT configuration details of members' companies.
The reseller, HP and another interested party all bid for the list and HP came in with the highest price.
HP said it bid to protect the privacy of its customers. The company staged its own user conference in Orlando, Florida, last month, to replace HP World.
