You cannot turn off the Undo or Redo commands, nor can you change the maximum number of actions Word stores in the Undo or Redo stacks (limited by resources and document size)(maximum document size of 32 megabytes without graphics).

NOTE: If you are experiencing out-of-memory or slow-performance problems, be sure to rule out other Word or system operations as the cause.

Under Protect document for, click Forms.

Click OK.

NOTE: If you do not actually want to protect your document as a form, click Unprotect Document on the Tools menu.
