 Exhibit 10.20 

FORM OF 

NONCOMPETITION AGREEMENT 

This Noncompetition Agreement (this “Agreement”) is entered into effective as of
                     between CDW LLC, an Illinois limited liability company (together with its successors and assigns, the
“Company”), and                      (the “Employee”). 

WHEREAS, the Company and its subsidiaries are currently engaged in the business of marketing and selling multi-branded
information technology products (including hardware and peripherals, software and accessories) and services (including comprehensive and integrated solutions) to business, government, education and healthcare customers and consumers, it being
acknowledged that the scope of the Company’s business will evolve over time; 
 WHEREAS, the Employee
acknowledges that in the course of the Employee’s employment with the Company or its subsidiaries, the Employee has and will become familiar with trade secrets and other confidential information concerning the Company and its subsidiaries
(collectively, as further described in Section 2 below, the “Confidential Information”) and that the Employee’s services will be of special, unique and extraordinary value to the Company and its subsidiaries; 

WHEREAS, the Employee acknowledges that the Company’s Confidential Information will retain continuing vitality
throughout and beyond the restricted period described in Section 1(a) below, and that should Employee leave the Company and work for a competitor during restricted period, it would be highly likely, if not inevitable, that Employee would use or
disclose the Company’s Confidential Information, and Employee therefore agrees that the restrictions in this Agreement are necessary to protect the Company’s legitimate business interests; 

WHEREAS, the Board of Directors of the Company has approved a Compensation Protection Agreement with the Employee (the
“CPA”); and 
 WHEREAS, as a condition to the Employee being entitled to become a party to the CPA,
the Employee is required to execute this Agreement. 
 NOW, THEREFORE, in consideration of the mutual promises
and agreements contained herein, in the CPA and in the overall employment relationship between the Company and the Employee, the adequacy and sufficiency of which are hereby acknowledged, the Company and the Employee hereby agree as follows:

 1. Noncompetition; Nonsolicitation. (a) The Employee agrees that for the period commencing
on the date on which the Employee’s employment with the Company or its subsidiaries terminates for any reason (the “Termination Date”) and ending on either (i) the eighteen month anniversary of the Termination Date if the
Employee is eligible, as of the Termination Date, to receive severance payments pursuant 

 
to Section 3 of the CPA, or (ii) the twelve-month anniversary of the Termination Date if the Employee is not eligible, as of the Termination Date, to receive any such
payments, the Employee will abide by the restrictions contained in Sections 1(a)(1) and 1(a)(2). 

(1) The Employee will not except as part of his authorized duties as an employee of the Company engage in,
participate in, form, or develop any Business (as defined in Section 1(a)(3)) being conducted or planned by the Company or any of its subsidiaries as of the Termination Date in any geographic area in which the Company or any of its subsidiaries
is conducting such Business or plans to conduct such Business as of the Termination Date. The restriction contained in this Section 1(a)(1) shall apply to the Employee engaging in, participating in, forming or developing any such Business
either directly or indirectly through any person, firm, corporation, partnership or other enterprise, or as an officer, director, stockholder, partner, investor, employee or consultant thereof, or otherwise. Without limiting the foregoing
restriction, but by way of illustration of its application, the Employee will not become an officer, director, stockholder, partner, investor, employee or consultant of any of the corporations or other enterprises set forth in Schedule I hereto
(including any affiliate of such corporations or other enterprises), it being acknowledged that (i) Schedule I is only a representative list of the Company’s current competitors and is not intended to include all of the Company’s
current competitors and (ii) new competitors of the Company may emerge over time. 
 (2) The
Employee will not directly or indirectly (i) solicit any CDW Employee or otherwise induce or attempt to induce any CDW Employee to terminate or abandon his or her employment for any purpose whatsoever or (ii) in connection with any
business to which the restriction contained in Section 1(a)(l) applies, call on, service, solicit or otherwise do business with any CDW Customer or any of its subsidiaries. 

(3) For purposes of Section 1(a)(1), “Business” shall mean any business conducted or
planned by the Company or any of its subsidiaries if the Employee, while employed by the Company or any of its subsidiaries, was involved in such business or had knowledge of such business. The Employee will be deemed to have knowledge of a Business
if the Employee received or was otherwise in possession of Confidential Information (as defined in Section 2) regarding such Business. 

(4) For purposes of Section 1(a)(2), a “CDW Employee” shall include any person that was
employed by CDW or any of its subsidiaries or affiliates either: (a) at any time within three months of the prohibited contact; or (b) at any time within three months of the Termination Date. A “CDW Customer” shall include
(a) any person or entity that purchased any products or services from CDW or any of its subsidiaries or affiliates at any time within a two year period prior to Employee’s termination (for

  

 2 

 
whatever reason) from the Company or (b) any person or entity with respect to whom, at any time during the one year period prior to the Employee’s termination (for whatever reason) from
the Company, the Employee submitted or assisted with the development or submission of a presentation or proposal of any kind on behalf of the Company or any of its subsidiaries or affiliates, acquired or had access to Confidential Information or had
contact with as a result of the Employee’s employment with the Company. 
 (b) Nothing in this
Section 1 shall prohibit the Employee from being (i) a stockholder in a mutual fund or a diversified investment company or (ii) a passive owner of not more than two percent of the outstanding stock of any class of a corporation, any
securities of which are publicly traded, so long as the Employee has no active participation in the business of such corporation. 

(c) If, at any time of enforcement of this Section 1, a court holds that the restrictions stated herein are
unreasonable under circumstances then existing, the parties hereto agree that the maximum period, scope or geographical area reasonable under such circumstances shall be substituted for the stated period, scope or area and that the court shall be
allowed to revise the restrictions contained herein to cover the maximum period, scope and area permitted by law. 

(d) Because the protection of the Company’s Confidential Information requires that Employee not perform the
activities described in this Section 1 for the full amount of time provided in Section 1(a), Employee agrees that the restricted period described in Section 1(a) shall be extended for any time during which Employee breaches this
Agreement, such that Employee does not perform the proscribed activities for a time period equal to the full amount of time provided in Section 1(a). 

2. Confidentiality. The Employee shall not, at any time during the Employee’s employment with the
Company or its subsidiaries or thereafter, make use of or disclose, directly or indirectly, any (i) trade secret or other confidential or secret information of the Company or of any of its subsidiaries or (ii) other technical, business,
proprietary or financial information of the Company or of any of its subsidiaries not available to the public generally or to the competitors of the Company or to the competitors of any of its subsidiaries (the information in clauses (i) and
(ii) being collectively referred to herein as “Confidential Information”), except to the extent that such Confidential Information (a) becomes a matter of public record or is published in a newspaper, magazine or other periodical
or on electronic or other media available to the general public, other than as a result of any act or omission of the Employee, or (b) is required to be disclosed by any law, regulation or order of any court or regulatory commission, department
or agency, provided that the Employee gives prompt notice of such requirement to the Company to enable the Company to seek an appropriate protective order. Promptly following the termination of the Employee’s employment with the Company or any
of its subsidiaries, the Employee shall surrender to the Company all records, memoranda, notes, plans, reports, electronic files computer tapes and software and other documents and data which constitute Confidential Information

  

 3 

 
which the Employee may then possess or have under the Employee’s control (together with all copies thereof). Employee must return all Confidential Information to the Company, whether it is
(i) a hard copy document; (ii) on a work, home, or laptop computer; (iii) on a blackberry, PDA, iPhone, or cell phone; or (iv) on an external hard drive, thumb drive, or any other piece of external media that permits the storage
of information. 
 3. Intellectual Property. The Employee shall not, at any time, have or
claim any right, title or interest in any trade name, patent, trademark, copyright, trade secret, intellectual property, methodologies, technologies, procedures, concepts, ideas or other similar rights (collectively, “Intellectual
Property”) belonging to the Company or any of its affiliates and shall not have or claim any right, title or interest in or to any material or matter of any kind prepared for or used in connection with the business or promotion of the Company
or any of its affiliates, whether produced, prepared or published in whole or in part by the Employee or by the Company or any of its affiliates. All Intellectual Property that is conceived, devised, made, developed or perfected by the Employee,
alone or with others, during the Employee’s employment that is related in any way to the Company’s or any of its affiliates’ business or is devised, made, developed or perfected utilizing equipment or facilities of the Company or its
affiliates shall be works for hire and become the sole, absolute and exclusive property of the Company. If and to the extent that any of such Intellectual Property should be determined for any reason not to be a work for hire, the Employee hereby
assigns to the Company all of the Employee’s right, title and interest in and to such Intellectual Property. At the reasonable request and expense of the Company but without charge to the Company, whether during or at any time after the
Employee’s employment with the Company, the Employee shall cooperate fully with the Company and its affiliates in the securing of any trade name, patent, trademark, copyright or intellectual property protection or other similar rights in the
United States and in foreign countries, including without limitation, the execution and delivery of assignments, patent applications and other documents or papers. In accordance with the Illinois Employee Patent Act, 765 ILCS 1060, the Employee is
hereby notified by the Company, and understands, that the foregoing provisions do not apply to an invention for which no equipment, supplies, facilities or trade secret information of the Company or any of its affiliates was used and which was
developed entirely on the Employee’s own time, unless (i) the invention relates (A) to the business of the Company or (B) to the Company’s or any of its affiliate’s actual or demonstrably anticipated research and
development, or (ii) the invention results from any work performed by the Employee for the Company. 

4. Enforcement. The parties hereto agree that the Company and its subsidiaries would be damaged
irreparably in the event that any provision of Section 1, 2 or 3 of this Agreement were not performed in accordance with its terms or were otherwise breached and that money damages would be an inadequate remedy for any such nonperformance or
breach. Accordingly, the Company and its successors and permitted assigns shall be entitled, in addition to other rights and remedies existing in their favor, to an injunction or injunctions to prevent any breach or threatened breach of any of such
provisions and to enforce such provisions specifically (without posting a bond or other security). The Employee submits himself or herself to the personal 

 

 4 

 
jurisdiction of the courts of the State of Illinois in any action by the Company to enforce the provisions of this Agreement. Employee will reimburse the Company for all costs (including
reasonable attorneys’ fees) incurred in connection with any action to enforce this Agreement if Company prevails on any material issue involved in such dispute. 

5. Notices. All notices and other communications required or permitted hereunder shall be in writing
and shall be deemed given when (i) delivered personally or by overnight courier to the following address of the other party hereto (or such other address for such party as shall be specified by notice given pursuant to this Section) or
(ii) sent by facsimile to the following facsimile number of the other party hereto (or such other facsimile number for such party as shall be specified by notice given pursuant to this Section), with the confirmatory copy delivered by overnight

If to the Employee, to last known address of the Employee in the records of the Company. 

6. Severability. Whenever possible, each provision of this Agreement shall be interpreted in such
manner as to be effective and valid under applicable law, but if any provision of this Agreement is held to be invalid, illegal or unenforceable in any respect under applicable law or rule in any jurisdiction, such invalidity, illegality or
unenforceability shall not affect the validity, legality or enforceability of any other provision of this Agreement or the validity, legality or enforceability of such provision in any other jurisdiction, but this Agreement shall be reformed,
construed and enforced in such jurisdiction as if such invalid, illegal or unenforceable provision had never been contained herein. 

7. Entire Agreement. This Agreement constitutes the entire agreement and understanding between the
parties with respect to the subject matter hereof and supersedes and preempts any prior understandings, agreements or representations by or between the parties, written or oral, which may have related in any manner to the subject matter hereof;
provided, however, that Employee recognizes that he or she may have entered into entirely separate agreements with the Company or its subsidiaries or 

 

 5 

 
affiliates that contain restrictive covenants (such as non-competition and non-solicitation promises), and Employee agrees that he or she will be bound to both the restrictive covenants contained
in this Agreement and the restrictive covenants contained in any other agreement that he or she has signed with the Company or its subsidiaries or affiliates. 

8. Successors and Assigns. This Agreement shall be enforceable by the Employee and his heirs,
executors, administrators and legal representatives, and by the Company and its successors and assigns. In the event of the consummation of a transaction initiated by the Company involving the formation of a direct or indirect holding company of the

references to the “Company” herein shall be deemed to be references to the new holding company.

the internal laws of the State of Illinois without regard to principles of conflict of laws.

Agreement shall affect the validity, binding effect or enforceability of this Agreement.

Acknowledgment. The Employee acknowledges that the restrictions contained herein are reasonable and necessary to protect the legitimate business interests of the Company and its subsidiaries and to prevent damage or loss to the Company and
its subsidiaries. The Employee further acknowledges that adhering to the restrictions contained herein will not unduly restrict his or her post-employment opportunities or otherwise impose an undue burden upon him or her. 

12. Counterparts. This Agreement may be executed in two counterparts, each of which shall be deemed
to be an original and both of which together shall constitute one and the same instrument.
