Item 5.03 Amendments to Articles of Incorporation or Bylaws; Change in Fiscal Year.

On October 19, 2006, the Board of Directors (the “Board”) of CDW Corporation (the “Company”) approved an amendment and restatement of the Company’s bylaws (as amended and restated, the “Amended Bylaws”) to make the following changes:

	•		Section 1 of Article I has been amended to eliminate the reference to the Company’s former registered agent.

	•		Section 8 of Article III has been amended to permit the Board of Directors, consistent with the Illinois Business Corporation Act, to establish committees comprised of only one director.

	•		Section 11 of Article III has been amended to remove a reference to an equity plan that is no longer in use.

	•		Section 8 of Article IV has been amended to clarify that the Treasurer is required to provide a specified report whenever requested by any of the Chairman of the Board of Directors, the President and the Board of Directors, but is not necessarily required to give such report at each meeting of the Board of Directors.

	•		Each of Section 1 of Article IV, Section 9 of Article IV and Section 3 of Article V have been amended to clarify language or correct typographical errors.

The Amended Bylaws became effective immediately upon their adoption by the Board. The description of the amendments to the Company’s bylaws is qualified in its entirety to the full text of the Amended Bylaws, a copy of which is attached as Exhibit 3.1 to this Current Report on Form 8-K and is incorporated by reference herein.
